This papercraft is Buttercup, one of the toys owned by Bonnie that appears in Disney's computer-animated adventure buddy comedy film Toy Story 3 and Toy Story Toons, created by Luisifer Chavez-Calderon. The size of finished model is about 260 (H) x 82 (W) x 260 (D) mm.
Buttercup is a white unicorn with a golden horn, mane, tail, hooves, and two pink hearts on his nostrils. Although his feminine appearance would suggest that he is female, Buttercup is actually a male unicorn.
Buttercup first appears in Bonnie's room when he meets Woody. He and Trixie welcome the cowboy nicely while Mr. Pricklepants shushes all of them. After their playtime with Bonnie, Buttercup and the others see Woody trying to leave. Woody explains that he already belongs to someone named Andy. After Woody mentions that Bonnie found him atSunnyside Daycare, Mr. Pricklepants and Buttercup inform Woody that Lotso runs Sunnyside like a prison. After hearing this, Woody returns to Sunnyside to rescue his friends.
After Andy donates his toys to Bonnie, Buttercup is seen giving Buzz a ride on his back. When Andy leaves, Buttercup is seen talking with Bullseye.
During the end credits, he is shown becoming close friends with Hamm, as the two are seen standing side-by-side when Woody reads his friends a message from Sunnyside written by Ken, when they watch an Alien and Mr. Pricklepants perform their rendition of Shakespeare's Romeo and Juliet, and when they enjoy watching Buzz and Jessie perform a paso doble.
