He wears lederhosen and usually views himself as a thespian. Mr. Pricklepants was made in Germany and is from the Waldfreunde collection of premium imported plush toys like Sonic the Hedgehog is from Japan. He is the de facto leader of Bonnie's toys and takes playtime as a job in acting. He warns Woody of how dangerous Lotso is and helps him get back to Sunnyside Daycare. In the credits, Mr. Pricklepants welcomes Woody and his friends to Bonnie's house and is seen playing Romeo in a version of Romeo and Juliet with one of the Alien toys as Juliet.
Mr. Pricklepants is a thespian hedgehog in lederhosen who says that he's "trying to stay in character," even when Woody tried inquiring as to his whereabouts. As Bonnie began playtime with her toys, she spits a jellybean onto Mr. Pricklepants in response to one of Woody's automated voices mentioning poison. Once Bonnie went to sleep, her toys helped Woody chart a path to Andy's house. But when he mentions passing a message to his fellow toys at Sunnyside Daycare, Bonnie's toys become alarmed and ask how he escaped. Mr. Pricklepants describes Sunnyside as "a place of ruin and despair, ruled by an evil bear who smells of strawberries." He points out Chuckles to testify. Despite their warnings that it's too dangerous to return to Sunnyside, Woody went anyway and rescued his friends. The next day, Woody returns to Bonnie's house with his friends, having been donated by Andy. When Andy leaves, Mr. Pricklepants is seen talking with Hamm.
In the end credits, he plays Romeo, alongside an Alien who is playing Juliet.
Mr. Pricklepants is first seen numbering the Aliens 1, 2 and 3 for an upcoming play that he is planning for his vacation plans. He can be seen portraying the humuhumunukunukuapua'a when Mrs. Potato Head shows Barbie and Ken the state bird and fish. He later serves as a waiter when Barbie and Ken are having their "dinner,"
Mr. Pricklepants is seen watching Woody attacking Mini Buzz and looking at the plan to get the real Buzz back. Mr. Pricklepants suggested acting their way into Poultry Palace, until the real Buzz showed up, having escaped via the drive-through.
He also appeared in Partysaurus Rex, although he didn't speak.
He is one of the toys that Bonnie brings on her road trip. When Bonnie's mom's car breaks down near the Sleep Well motel, Mr. Pricklepants tells the toys that the roadside motel is a perfect location for a horror movie. This is his first leading role in the Toy Story franchise.
