Kristoff is the tritagonist of Disney's 2013 animated feature film, Frozen. He is a Sámi ice harvester who later becomes the travel companion and love interest of Princess Anna, during the events of her quest to find Elsa the Snow Queen.
Kristoff was orphaned at a young age and placed in an orphanage thereafter. He was nevertheless too adventurous and free-spirited to be contained in such a facility; he spent a majority of his time sneaking out and exploring the wilderness around him. With a fascination of ice, Kristoff also occupied his time by tagging behind Arendelle's team of ice harvesters to observe their ethics in hopes of garnering their skill and eventually becoming an ice harvester, himself.
Kristoff is always accompanied by his reindeer, Sven — his pet, best friend, and business partner. The two met during Kristoff's childhood as an orphan, wherein during which, he found and rescued the reindeer fawn. Since then, the two became inseparable and built a relationship akin to that of two brothers. Kristoff's care for Sven was so great that he eventually began living by the philosophy that "reindeer are better than people", to which Sven would agree. Furthermore, although Sven cannot speak, both he and Kristoff have a mutual understanding of one another. So much so, that Kristoff has a habit to literally voice Sven's thoughts in a gruff, goofy, exaggerated tone. Sven doesn't seem to mind, and the voice overs are surprisingly accurate. Not only does this act as a quirk, but as a way for Kristoff to guide his actions with a moral compass, as he uses Sven's selflessness to convince him to do the right thing, should he feel reluctant.
- Kristoff is a true outdoorsman. He lives high up in the mountains where he harvests ice and sells it to the kingdom of Arendelle. Rough around the edges, Kristoff's the strong, no-nonsense type, who follows his own set of rules. He may seem like a loner, but he always has his best friend by his side—a loyal and extremely mangy reindeer named Sven.
During his first proper introduction in the film, Kristoff is presented as a miserly loner, with a lack of respect for those around him—specifically in terms of personal boundaries and sensitivity. This is a direct result of growing up with a family of mythical creatures and wildlife, as opposed to other humans. Though his upbringing included a large family and at least one close friend, Kristoff tends to look out, mostly, for himself and can be rather selfish from time to time because of this, with his focus primarily on his ice business and life upon the mountains. The ice harvester spent a large portion of his early life in the mountains because of this, becoming an individualist and avid survivor in the wilderness, and constantly proving himself to be self-reliant and efficient when facing various perils throughout the course of the original film.
In spite of his loner nature, and dislike for society, Kristoff has a loving heart, and at his core, is rather harmless, innocent, and protective. This is first evidenced by his relationship with Sven, whom he treats as his pet and closest friend, and is shown to value the reindeer's life above his own several times. Kristoff's inner softness and loving aura is further emphasized by his family, the trolls, who reveal Kristoff to be (despite his various flaws and shortcomings) sensitive and sweet when given the same treatment, which he proves through his friendship and eventual relationship with Anna.
Through Anna, Kristoff is shown to be loving, respectful, and completely selfless and sacrificial. Eventually falling for the princess' fun-loving nature, selflessness, and persistence, Kristoff allows himself to open up to the world around him, revealing himself to be rather bashful and quirky, mirroring Anna's personality. Also as a result of his love for Anna, Kristoff is willing to risk his own life and happiness, without hesitation, all in hopes of the former's own happiness. This ties into a pivotal line featured in the film: "Love is putting someone else's needs before yours..."; which was directly used to reference Kristoff's willingness to conceal his affections for Anna, for the sake of the princess' possible future with another. As mentioned, he mirrors Anna in his quirkiness, best evidenced by his relationship with Sven, as the two have been shown to nonchalantly share food, "sing" duets, and engage in "conversations"—a further example of his peculiar traits.
Quite notably, however—midst a cast of colorful and larger-than-life characters in a world to match—Kristoff appears to be more of a straight man, reacting to the mystical situations he and the other characters encounter with a generally down-to-earth viewpoint. Though not a pessimist, he acts more of a realist, though his care for others ultimately leads him to perform death-defying acts for the greater good.
In Frozen Fever, Kristoff's softer side is shown to have grown, and become a more prominent aspect of his personality. With Anna's sister, Elsa, he is shown to be fairly laid-back, comforting, and encouraging, looking on the brighter side of a situation, no matter the level of importance. Nevertheless, he is still shown to become flustered around Anna, as a result of his affections for her.
Kristoff's build is a distinct variation on most male leads in Disney animated features (Hans is a perfect example of the traditional stature). On the flip side, Kristoff has broad shoulders and a muscular build. His build is a realistic consequence of his rough life as a mountain-dwelling ice harvester.
Kristoff is rugged and 21 years old, the same age as Elsa, at the time of the movie. Like the sisters, he has blond hair (more golden than Anna's strawberry-blonde hair, but not as pale as Elsa's platinum blonde hair) which is later described as "unmanly" by the trolls (in the song "Fixer Upper"). He also has light brown eyes and fair skin with a few freckles across his nose. His nose is quite big and his cheeks tend to redden a lot, because of the cold weather.
At the beginning of the film (when he is a child), his outfit consists of a royal purple long-sleeved shirt, dark trousers, and a purple sash. When we next see him as an adult, he is wearing a thick dark tunic with a fur-lined burgundy dark crimson collar and a blue patch on his right elbow, a burgundy sash tied around his waist, a dark blue long-sleeved undershirt, olive mittens, thick dark trousers, a dark bobble-hat (which he later gives to Anna when she is freezing to death) and fur-lined dark brown boots with pointed toes. At the end of the film, he wears pretty much the same outfit, minus the thick tunic and gloves, because it has become much warmer.
- “Cuties... I'm gonna keep you!”
- ―Bulda upon adopting Kristoff and Sven
As an 8-year old orphan, Kristoff is first seen attending a session of ice harvesting amongst a group of burly harvesters. Accompanied and assisted by Sven, Kristoff watches intently as the elders go about their work for the day. By night, Kristoff manages to obtain his own, small block of ice, much to his pride, and follows behind the harvesters as they make their leave from the mountains.
Meanwhile, an accident has occurred at the castle of Arendelle. Princess Elsa (born with power over ice and snow) has accidentally struck her sister, Anna, in the head with her magic. Unconscious, Anna is taken into the care of her parents, King Agnarr and Queen Iduna, and rushed to a legendary valley populated by a colony of trolls. During their trip, the horses of Agnarr and Iduna rush passed Kristoff, while leaving a peculiar trail of ice. Curious, Kristoff and Sven follow the royal family, arrive in the valley, and watch in hiding as their business unfolds. While covered, they are discovered by a female troll named Bulda. Bulda instantly takes a liking to Kristoff and Sven and decides to adopt them.
In the following years, Kristoff is raised under the loving and supportive care of the trolls. Thirteen years after his adoption, Kristoff has since become a professional ice harvester, seen selling ice alongside Sven in Arendelle's village square.
- “The only one crazy enough to be out in this storm is you, dear. [Krisotff enters the room] ...You and this fellow.”
- ―Oaken to Anna.
On the night of Princess Elsa's coronation as queen, her powers over ice and snow are revealed to the public. Stunned by the revelation, the people call Elsa out as a "monster", prompting her to leave the kingdom. During her escape, Elsa accidentally plunges Arendelle and its surrounding territory into an eternal winter. She retreats to the North Mountain, and area Kristoff is near. As the storm covers the land, Kristoff and Sven travel to Wandering Oaken's Trading Post and Sauna for supplies and carrots. Inside, he encounters an adult Princess Anna, who is in search for Elsa. When asked by the shop's owner, Oaken, about the peculiar weather, Kristoff nonchalantly notes it to be coming from the North Mountain. Enticed, Anna attempts to gain further information from the mountain man, but during the interaction between him and Oaken, the prices for Kristoff's mountain gear are revealed to have been piked, due to the supply and demand issue stemmed from the unexpected winter. Kristoff makes the poor choice of calling Oaken a "crook" in response and is thrown out of the establishment immediately. Despite his lack of goods, Kristoff and Sven retire to a nearby barn to rest of the night. After a lullaby to welcome sleep, the duo is visited by Anna. The princess asks Kristoff to escort her to the North Mountain, though Kristoff refuses. Anna then reveals to have purchased the material Kristoff wanted from Oaken and demands that the mountain man complies with her request in gratitude for her services, additionally claiming to know the secret to stopping the winter. With his business in peril, Kristoff assent to Anna's proposal, and he, Sven, and the princess set off that night, per the latter's orders.
- “Hold up! We're coming!”
- ―Kristoff agreeing to aid Anna, despite having the chance to back out
As the travel begins, Kristoff inquires Elsa's reasoning behind freezing the entire kingdom. He's incredulous at Anna falling for Hans and wanting to marry him within hours of meeting him. The conversation is cut short when a pack of hungry wolves attacks them. They manage to evade the wolves by jumping over a chasm, but the sled is lost, plummeting to the bottom of the cliff, along with the supplies. After taking a few moments to recover from the scare, and after seeing the trouble she's caused, Anna offers recovery for the lost sled and supplies, in addition to continuing her search alone, in hopes of saving Kristoff and Sven from any further turmoil. As she prepares to leave, Sven urges Kristoff to continue aiding her, though the mountain man expresses apprehensions in fear of further danger. However, knowing Anna would die on her travels should she endure them alone, Kristoff makes the decision to continue forth, by her side, to help aid and protect the princess throughout the remainder of the journey, much to Sven's delight.
The following day, the group comes across a talking snowman named Olaf, who dreams of experiencing summer. Knowing the consequences of this dreams, Kristoff sadistically shows the desire to reveal exactly what happens to snow during the summer season, but a protective Anna prevents him from doing so. Olaf's dream aside, the snowman also knows the location of the Snow Queen and offers himself as the group's guide, to which Anna and Kristoff accept. After a bit of travel, the group finally arrives at the Ice Palace, leaving Kristoff in awe at the beauty ice is capable of forming. In spite of this, Kristoff is forced to remain outside per Anna's wishes, as she wouldn't want Elsa to cause more havoc at the sight of a man by the former's side (referring to the debacle with Hans). Kristoff expressed grief over the matter, but eventually abides and waits patiently outside alongside Olaf. Kristoff enters the ice palace upon hearing a commotion, which appears to have resulted in Anna being struck in the heart. Kristoff remains by her side as Elsa orders the group to leave, which Kristoff tries to oblige to out of fear, though Anna refuses to leave the palace without her sister.
This forces Elsa to create a giant snow monster named Marshmallow to forcefully throw the group out. Kristoff simply accepts Marshmallow's rudeness, but Anna retaliates by throwing a snowball at the beast, which immediately angers him. Kristoff and Anna rush down the mountain while being hotly pursued by Marshmallow. Throughout the chase, Kristoff continuously goes out of his way to protect Anna, proving his selflessness, and is evidently highly impressed by her self-sufficiency against the snow beast. Once they reach the cliff of a mountain, the ice harvester creates a snow anchor for the two to safely travel down, though Marshmallow grabs hold of the rope and slowly pulls them to their doom. Kristoff tries to free Anna but is briefly knocked unconscious in the process, leaving Anna to save them both by cutting the rope with Kristoff's knife.
The two land safely on a blanket of snow below, and are reunited by Olaf and Sven. After Kristoff assists Anna in getting back onto her feet, the two share a loving glance in mutual gratitude for their previous actions. Unfortunately, this is short lived, as Anna starts to panic over Elsa's refusal to cooperate, with the storm still going strong. She couples her anxiety with the fact that the blizzard will result in the failure of Kristoff's ice business, to which the latter replies by calmly assuring his ice business is no longer a priority. Just then, Kristoff notices Anna's hair beginning to turn white and deduces that the phenomenon is due to Elsa striking Anna in the heart. Fortunately, Kristoff believes he has a solution, and leads the gang to the Valley of the Living Rock, where the trolls reside.
- “Kristoff's home!”
Along the way, Kristoff's appears to have abolished his defenses and starts to open up to Anna by revealing his past, including how he and Sven were lonely orphans until they were taken in by their adoptive family, which Anna is touched by. Though he loves his family, Kristoff warns Anna that they can be rather overbearing, stubborn, and loud at times, to which Anna responds by claiming they sound wonderful. With his insecurities somewhat lowered, Kristoff introduces Anna and Olaf to his family, who are currently dormant as rocks. Anna and Olaf assume Kristoff is mentally unstable, and make an attempt to leave until the rocks finally reveal themselves to be sentient trolls. A warm reunion follows, as Grand Pabbie, who Kristoff is searching for to help Anna, is said to be asleep. The trolls then notice Anna standing by, and Bulda immediately assumes her to be Kristoff's girlfriend. The two deny any romance, but Bulda and the trolls try to convince them otherwise, telling them they're meant for each other. They arrange an entire wedding, but before it is complete, Anna nearly faints and loses balance, with Kristoff catching her in his arms and anxiously informing the trolls she's freezing cold. Pabbie, although he is powerful, is unable to heal her, and he tells them that unless Anna can perform an act of true love, she'll freeze and die. Bulda believes the act of true love would perhaps be "true love's kiss," which prompts Kristoff to take Anna back to Arendelle so she may receive a kiss from Hans, her supposed true love.
Race Back to Arendelle
- “No, Sven, we're not going back! She's with her true love!”
Once they enter the kingdom and the castle gates, Kristoff escorts Anna to the care of the royal staff. Now that she has returned to her royal care, as well as her true love, Kristoff feels his time of usefulness to Anna has reached its limit, and sadly takes his leave from Arendelle with Sven by his side. Unbeknownst to him, Hans doesn't really love Anna, as he was only using her to become the king of Arendelle, thus denying her a kiss and leaving her to die in a locked room within the castle. Afterward, Olaf, who got separated from the group during their arrival in the city, finds Anna lying in the library freezing, and starts a fire to lessen her curse until an alternative plan comes to mind. Meanwhile, Kristoff and Sven continue their travels into the mountain, though the latter suddenly takes a stand and pressures Kristoff to return. Kristoff's insecurities drive him to refuse when suddenly, a giant snowstorm (created by a frightened Elsa) begins to form around the castle.
Kristoff and Sven presume Anna to be in danger and rush off together to rescue her. From the castle, Olaf is able to witness the duo making their return and informs Anna. Kristoff's heroism and devotion lead Anna to believe that the former is the one she must kiss, as it is he who truly loves and cares for her. With this new spark of motivation, Anna and Olaf exit the castle and enter the fjords, just as Kristoff and Sven enter the icy platform, themselves; due to the blinding whiteout of a storm, however, each party has a difficult time reaching the other. Before long, the storm becomes deadly, creating cracks in the icy surface, revealing freezing waters. Sven tries to narrowly escape the hazards, but falls into the water and apparently drowns. Kristoff looks on in horror, but Sven survived and makes his way to safety before urging Kristoff to push forward.
At one point, the blizzard comes to a sudden standstill, clearing the pathway for the lone Kristoff. He is soon able to spot Anna and rushes to her across the fjord. As Anna weakly tries to meet him halfway, she notices Hans and Elsa not too far, where the evil prince is seconds away from murdering the Snow Queen with his sword. Sacrificing her life for her sister, Anna takes one final look at Kristoff before leaping to the rescue, putting herself between Elsa and Hans, and freezing to death seconds before the sword hits her. The sword shatters against Anna's frozen hand, and Hans is knocked out from the impact just before Elsa realizes what happened. She tearfully mourns her sister, as Kristoff, Sven, and Olaf, who have just arrived, watch sadly from a short distance.
However, Anna's sacrifice was an act of true love (for her sister), and she is soon revived from her death, much to everyone's complete joy. Along with Anna's revival comes the entire kingdom's thawing when Elsa realizes she needs to harness the power of love to end the eternal winter. As Hans awakens, Kristoff's ready to beat him up for what he did. But Anna stops him, and punches Hans herself, knocking him overboard. Afterward, the two sisters solidify their reunion with a hug, and in during which, Anna looks lovingly, and appreciatively, to Kristoff.
Following Arendelle's restoration, a celebration is held by Elsa in the castle courtyard. Before attending, Anna takes a blindfolded Kristoff to the docks, where she surprises him with a brand-new sled and lute. Taken aback out of modesty, Kristoff tries to deny the offer, but Anna insists, announcing that Elsa has dubbed Kristoff Arendelle's official Ice Master and Deliverer. An elated Kristoff twirls Anna in his arms, and awkwardly asks permission to bestow a kiss of gratitude. Anna accepts, and the two share a romantic moment, initiating a budding relationship.
Kristoff is last seen joining Elsa, Anna, Olaf, and Sven in the castle courtyard, where citizens of the kingdom gather to embrace the return of their queen by enjoying a newly-created ice skating rink.
Following the events of the film, Kristoff and Sven have become welcomed members of Anna and Elsa's extended family. On one particular day, Anna's 19th birthday arrives, and both Kristoff and Sven are enlisted to assist Elsa and Olaf in making preparations.
As Elsa prepares the cake in the castle courtyard, Kristoff and Sven handle the decorations, notably the banner. Though Elsa feels anxious about the event, the perfectionist inside of her causing distress, Kristoff serves as a token of optimism and reassures the Snow Queen that all is well. Eventually, it is time to awaken Anna, and Kristoff is left in charge to ensure the festivities and decorations remain intact during Elsa's absence. After the Snow Queen's departure, Kristoff, Olaf, and Sven eventually fall asleep as they await the queen and princess' return, only to be awakened by miniature baby snowmen known as Snowgies, who immediately begin causing mayhem around the courtyard.
Flustered, Kristoff immediately takes action, with Sven and Olaf following behind. However, the Snowgies prove to be elusive, and they soon spot the birthday cake, instantly marking it as their delectable target. Noticing this, Kristoff ensures the cake remains in piece, but as the day goes along and more Snowgies randomly appear, the decorations are individually ruined. Even so, by the time Anna and Elsa arrive, the Snowgies have been tamed and the decorations restored as the surprise party kicks off. Kristoff greets Anna with a soft smile and wishes her a happy birthday, as well as excitingly proclaiming his love for her before the cake is distributed by Sven.
At the end of the short, Kristoff, Sven, and Olaf travel to the North Mountain to move the Snowgies in with Marshmallow in Elsa's ice palace.
Kristoff plays a supporting role in the LEGO parody special. This version of Kristoff is somewhat pompous and pretentious as he repeatedly tries to impress Anna and Elsa with his survival skills, only to fail and end up humiliated in the process. He tends to be the butt of many jokes as a result of this.
An emoticon version of Kristoff appeared in the Frozen and Frozen Fever entries of the As Told by Emoji short series.
Taking place two years after the events of the film, and approximately a year before the first Dark Curse, Kristoff and Anna are engaged to be married.
After discovering their parents were heading off to a land known as Mist Haven for an unspecified reason involving Elsa, Anna boards a ship heading for the mysterious land alone, leaving Kristoff behind to both keep Elsa company and keep her distracted. After searching for Anna for a short while, Elsa confronts Kristoff and Sven on her whereabouts. Kristoff attempts to hold the fort, but Elsa eventually realizes the truth and heads out to Arendelle's port in order to stop her sister from journeying off alone. Kristoff follows behind, but by the time they arrive, Anna has already departed.
Sometimes during Anna's quest in the Enchanted Forest, Elsa begins to feel worried for her sister's safety. Kristoff, however, is confident that Anna will be fine. When one of the scouts reported that Hans and his twelve brothers are approaching Arendelle from the Southern Mountains, Kristoff offers to sneak into the mountains to spy on them, only for Elsa to insist that, as the ruling Queen of Arendelle, she should handle the situation herself. Nevertheless, Kristoff decides to go against her decision and sneak into the Southern Mountains with Sven. He managed to find their campsite and eavesdrop on the princes' new plan to take over Arendelle. He returns to Elsa and informed her that they are planning to use a special urn that can trap people like Elsa with magical powers. He suggested having a few soldiers accompanied him to the North Valley to find and destroy the urn before Hans and his brothers find it first. On Elsa's insistent, he should take only her. They travel to the North Valley, where the urn is hidden in a cave. Upon finding it, Hans and three of his brothers arrived and surround them. Hans holds Kristoff hostage and demands Elsa to surrender the urn. Elsa eventually gives Hans the urn and tells Kristoff to go find Anna and save Arendelle. As he's held captive by one of Hans' brothers, Kristoff could only watch as the evil prince uncaps the urn and pours out a living white liquid substance that will supposedly trap Elsa. However, instead of latching onto Elsa, the liquid moves to an isolated spot next to her and morphs into the Snow Queen. Kristoff and Elsa watch as the Snow Queen turns Hans into an ice statue, as the result of his insult in calling Elsa a monster, while his brothers flee the scene. Though the Snow Queen is wary of Kristoff, Elsa convinced her that he is her ally.
Prior to Anna's return from the Enchanted Forest, Kristoff tries to get a moody Sven to eat his carrots. Exasperated, he wonders out loud what's wrong with him. Anna then appears at the stable's doorway, having returned from her trip through her temporary control of Rumplestiltskin's dagger, and suggest that the reindeer probably missed her. Overjoyed by her return, Kristoff embraces Anna in a hug and they share a kiss.
Later, Anna was discussing with Kristoff about her introduction to the Snow Queen, Ingrid, revealed to be her and Elsa's aunt. Though doubtful about Ingrid's family ties, since she isn't found in any of the family portraits or records. Unbeknown to both, the suspicions are correct. After Anna is released from Ingrid's magic spell, where she unexpectedly imprisoned Elsa in the urn while blinded by her anger, the Snow Queen furiously moves to choke her only to be stopped by an intervening Kristoff, armed with his ice pick. Kristoff and Anna can only stand idly by as Ingrid, after being consumed with disgust and remarks how the two are looking at her like a monster, turns the couple into frozen statues as Arendelle itself also ices over.
30 years after being frozen in a state of suspended animation, Kristoff, Anna, and the kingdom of Arendelle finally thawed out as the result of Ingrid casting her Spell of Shattered Sight in Storybrooke. While they were discussing on rescuing Elsa from Rumplestiltskin, they were confronted by an unfrozen Hans and his brothers, who had just declared Arendelle as his kingdom. Feigning that Anna had dethroned her sister, Hans had the couple arrested for treason, but Kristoff and Anna, after pretending they surrender, managed to fight their way out and escape.
After escaping the castle, Kristoff and Anna decide to go to the pirate Blackbeard to look for the wishing star. When they get to Blackbeard, they say they will pay for the wishing star in his weight in gold. Hans and his brothers suddenly appear and tell Anna and Kristoff that the whole thing was a setup. Hans then had the two tied up and placed in a large trunk, where he had them toss overboard at the bottom of a spot in the sea called Poseidon's Boneyard, where Anna and Elsa's parent died several years prior. Though the trunk is filling up with water fast, Kristoff managed to free himself and Anna from the binds. Thinking this is the end for them, Anna begins reciting her marriage vows to him. He assures her that they will marry once they escape. With the trunk almost completely filled up with water, they proclaim their love for each other and prepare to meet their fate. Fortunately, through Elsa wishing that she could know what happened to her sister and that she could see her again, the trunk they're in are magically transported to Storybrooke. After reuniting with Elsa, and meeting Emma Swan, the group head to the sheriff's office. Finally, the inhabitants of Storybrooke brace themselves as the curse falls upon the town and begins to take its effect. Although Anna, Elsa, and Emma will be immune to the curse, Kristoff, after trying to resist, looks at Anna one last time before he's affected.
Later, an affected Regina, in her Evil Queen attire, arrived at the sheriff's station originally hunting down Emma but finds Kristoff, Anna, Mary Margaret and David instead. Before she duels with Mary Margaret, Regina teleported Anna and Kristoff to the beachfront. Frustrated, Kristoff gives up on the current situation and attempt to swim back to Arendelle, only to be knocked out by Anna using the bottle that contains her mother's message. The message Anna found would eventually convince Ingrid to end the curse, but at the expense of her own life.
With Ingrid now dead, Kristoff, Anna, and Elsa return home. After returning to their kingdom and reclaiming it from Hans, Anna and Kristoff eventually got married.
Kristoff plays a central role in the book series. In the first installment, Journey To The Lights, he takes Anna and Elsa to the Crystal Ceremony, an annual event held by the trolls in which Grand Pabbie grants crystals to the deserving younger trolls. Kristoff considers this particular ceremony to be fairly special, compared to the others, due to the fact that his close friend, Little Rock, is being honored. Little Rock once saved Kristoff's life—in the past, some of the younger trolls made a sandwich for Kristoff, not knowing the ingredients they used were poisonous to humans. Little Rock was able to identify the hazard and smacked the food away before Kristoff could consume it.
The story also reveals that Kristoff tends to celebrate his mother's birthday by picking flowers and singing songs.
Kristoff and Anna are the focus of Anna Is Our Babysitter, where Grand Pabbie and the trolls must leave the Valley of the Living Rock for a congress of magic, leaving the infant trolls in the hands of Kristoff and Anna.
In Spring Fever, it is learned that Kristoff has had a lingering dream of competing against fellow ice harvesters in the annual "Ice Games", which acts as an Olympic-esque event for ice harvesters, and their families. Unfortunately, only humans can participate, and since Kristoff's only friends were Sven and the trolls, he was repeatedly ineligible to participate. Upon hearing this, however, Anna and Elsa volunteer to join Kristoff's team, to finally bring his dream to fruition.
Kristoff makes various, special appearances at the Disney theme parks, though he is currently unavailable for meet-and-greets. When asked about him, Anna and Elsa mention that he is back in Arendelle.
Kristoff also appears in Frozen: Live at the Hyperion.
On July 5, 2014, Kristoff made his Disney theme park debut at Disney's Hollywood Studios during the Frozen Summer Fun event. Here, Kristoff appears in the Frozen Royal Welcome introductory parade, the Frozen Sing Along show (where the story of the film is told with live accompaniment in the form of Kristoff, Anna, and Elsa) and the finale fireworks display. He appears during identical events in Disneyland Paris.
During these events, the ice harvester also appears during A Frozen Holiday Wish show, serving as the host alongside Anna, Elsa, and Olaf.
In Tokyo Disneyland, Kristoff appears during the 2016 parade for Anna and Elsa's Frozen Fantasy, featured on his own float—shared with Anna and Sven—modeled after the sleigh Anna gifted him with at the end of the film.
In France, Kristoff appears in Disney Dreams!.
In the China park, Kristoff's likeness appears on the Frozen mosaic mural inside of the Enchanted Storybook Castle. He also makes an appearance during the Frozen Sing-Along Celebration show in the Fantasyland theater.
- Ice Harvesting is a seasonal occupation that does best during the summer months; men who take up such jobs often have problems finding enough money to live on during their 'off' season. It is implied that Kristoff has no permanent place of residence and is financially challenged. A line from Disney on Ice Presents Frozen, where Kristoff says he comes from "nowhere in particular" suggests this. Additionally, in original drafts, Kristoff only helped Anna out because of the money.
- Across Europe, there are stories of Changelings and Fetches - when Trolls steal a human child and replace them, sometimes with fairies, and sometimes a log of enchanted wood that becomes 'sick' and dies. The stories include that the Trolls were particularly attracted to blond hair and beauty, and often treated the stolen child as one of their own. In return, they gave the child (sometimes the Changeling; sometimes the Fetch) gifts such as strength, stamina, or an affinity for the wild. This is very similar to what happened to Kristoff, which would make him a Fetch (the stolen child).
- Kristen seems to be based on Robber Girl from the original story "The Snow Queen". In the original story, his pet's name is Bae instead of Sven.
- According to the director/writer Jennifer Lee, Kristoff is 21, the same age as Elsa.
- It should be noted that Kristoff's current design is much like an early design for Flynn Rider from Tangled, known as "Bear Flynn" or "Bastion". That design was bulky, largely built, and that version of Flynn Rider was sweet and charming. Later, Flynn became suave and dashing, while Kristoff is sweet and introverted, but both are of the Loner archetype.
- Both Kristoff's voice actor (Jonathan Groff) and Elsa's voice actress (Idina Menzel) have portrayed recurring characters on the FOX television series Glee. Groff played Jesse St. James, a love interest to the character of Rachel Berry. Menzel played Rachel's mother, and the vocal coach of Jesse's Glee Club, Vocal Adrenaline.
- Although it was not mentioned in the film, Kristoff's last name, Bjorgman, was confirmed in the Essential Guide. In Scandinavian, 'Bjorg' means 'help' or 'salvation'.
- Due to time, a scene featuring Kristoff climbing, using his pickaxe all over the mountain cliffs, was deleted.
- Apparently, Kristoff does not have very good hygiene; in one of his voice-overs for Sven, "Sven" admits Kristoff does not smell better than a reindeer. Also, the trolls mention in the song "Fixer Upper" that "though we know he washes well, he always ends up sort of smelly" and how he "tinkles in the woods" and "has a couple of bugs." He also shares carrots with Sven, allowing Sven to take a bite, then taking a bite himself - when he is seen briefly in Arendelle with Sven, Sven takes the whole carrot in his mouth, but Kristoff tells him to share. Sven then spits part of the carrot out (now saliva-covered), and Kristoff takes a bite from it.
- According to the book Olaf and Sven on Thin Ice, Kristoff once fell into the frozen lake trying to go get ice when he was younger. After this, the other ice harvesters called him Icicle.
- Kristoff 'dubs' Sven saying "People will beat you and hurt you and cheat you; every one of them's bad, except you." Sven seems to agree. This strongly suggests that Kristoff has had some very bad experiences with other humans.
- In the credits of Frozen, there is a disclaimer which states that Kristoff's views are his own views and do not represent the views of the filmmakers or The Walt Disney Company as inferred from when he asks Anna, "What if you hate the way he eats? What if you hate the way he picks his nose?" Anna counters, "Excuse me, sir, he is a prince!" Kristoff's response is "All men do it." The disclaimer reads as follows: "The views and opinions by Kristoff in the film that all men eat their boogers are solely his own and do not necessarily reflect the views or opinions of The Walt Disney Company or the filmmakers. Neither The Walt Disney Company nor the filmmakers make any representation of the accuracy of any such views and opinions."
- Kristoff's involvement in the film's opening was used to connect his story and ties with Anna early in the film, as it was her actions (accidentally becoming injured and having to visit the trolls) that led to Kristoff finding a permanent family. This would later reciprocate with Kristoff aiding Anna in her quest to rekindle her bond with Elsa.
