The Stabbingtons appear to be twins, both having red hair, light blue eyes, big noses, big jaws, muscular bodies and the same height. Their haircuts are almost similar (their fringes are combed in different directions), their skin tone the same, both have red cheeks, noses and ears, big eyebrows and dark rings underneath their eyes. They have scars too, both underneath their mouths. Sideburns has a slightly curved one on the right side of his face. Patchy has a vertical one on the left side of his face. Sideburns wears a sleeveless green shirt, his weapon is a long sword on his back, has sideburns and his ears are edgier. Patchy wears a dark, sleeveless shirt similar to his brothers but wearing a long-sleeved shirt underneath, has a big knife, round ears, and an eye patch on the left eye.
The Stabbington Brothers are first seen with Flynn, heading for the castle to steal a royal crown that belongs to the missing princess. The brothers hoist Flynn down with a rope to retrieve it, but he gives them away. The three obtain it successfully, but the guards rush for them and a chase begins. When the trio reaches a dead-end, the brothers will only let Flynn go first if they have that satchel that holds the crown. Although they had the satchel, Flynn betrays them and was able to grab the satchel from under their noses, much to their anger. Stranded, the brothers are arrested but roam along with the guards as prisoners in chains. While at the Pub Thug where Flynn and his new allies Rapunzel and Pascal are located, the two escape and then try to catch Flynn as he escapes. However, they are overwhelmed by the collapsing river water built up by the dam, which is destroyed in the process where Maximus attempts to apprehend Flynn.
They survive the chaos, exiting the Pub's secret passage. The two stumble upon a woman, Mother Gothel. She strikes a deal with the two and reveals the secret of Rapunzel's hair, which they find more valuable than the crown. After Rapunzel and Flynn enjoy a romantic evening watching the lanterns, Flynn spots the brothers and brings the satchel to them in the hopes that they will leave Rapunzel and him in peace. The brothers, however, point out to Flynn that they are aware of Rapunzel's hair, and want her instead of the crown. The brothers render Flynn unconscious and tie him up to their boat, pushing it back into the sea to sail back towards the kingdom. Cleverly, through Mother Gothel's commands, the brothers made it seem as if Flynn was escaping with the crown, having Rapunzel believe he was abandoning her, trading her and her magic hair for the crown.
The brothers confront Rapunzel and tell her just that, breaking the girl's heart. They then prepare to kidnap her, planning to use her magic hair to make a fortune. However, Mother Gothel betrays them and knocks the duo out with a branch, making it seem as if she was rescuing Rapunzel as her entire plan was to keep Rapunzel with her, hidden away in their tower in the forest. Offscreen, the brothers are arrested and taken to the prisons along with Flynn. They are last seen in their prison cell as Flynn is being escorted to his execution. In fury, Flynn grabs one of them and demands to know what happened to Rapunzel and how they knew about her hair. They fearfully tell Flynn that an old lady was behind it all. They aren't seen for the remainder of the film.
The Stabbington Brothers make a small cameo in Tangled Ever After where Rapunzel and Eugene (Flynn Rider) wed. They are seen at the very end, weeping as Rapunzel and Eugene share their first kiss as a married couple. This scene in the short shows heavy signs of reformation as the brothers were not only invited to the wedding by Rapunzel and Eugene but also showed genuine happiness for the loving couple.
The Stabbington Brothers (revealed to be named Sideburns and Patchy) appear in the episode "Cassandra v. Eugene". Taking place before the events of Tangled: Ever After, the brothers manage to escape their cell and seek revenge against Flynn. They kidnap Rider and Rapunzel's lady-in-waiting Cassandra to use as "human shields" as they make their way out of the dungeons. They are confronted by the guards, and during the confrontation, the brothers learn that Cassandra is the daughter of the captain. Sideburns threatens to kill Cassandra should the captain refuse to stand down, allowing the brothers to escape with both Cassandra and Eugene still in their grasps. Once they're in the clear, Patchy prepares to kill the captives, though Sideburns decides to keep Cassandra alive to use as leverage against the captain. Nevertheless, the brothers are equally ready to exact vengeance on Flynn right then and there, but they were distracted long enough for Cassandra to knock them unconscious. By the time they awaken, the guards are on the scene, and Eugene and Cassandra have already made it to safety. The brothers are then taken into custody once more.
The Stabbington Brothers appear in the Flynn's Tangled Tales short "Barrel Blast" on the Tangled blu-ray.
Emoticon versions of the Stabbington Brothers briefly appeared in the Tangled entry of the As Told by Emoji short series.
The brothers make a brief cameo appearance, chasing Rapunzel, in the 2015 rendition of World of Color, during the celebration of Disney animated feature films.
- Although both characters are credited, Patchy has no actual lines of dialogue in the film.
- In Disney Enchanted Tales, it's revealed that Flynn was the one who approached the brothers to join him on the Crown theft-and that he had preconceived on how he'd get rid of them. However, whether this game is completely canon is still questionable.
