He is the most competent of Bonnie's toys. He first meets Woody when Bonnie was play tea party with them and later helps Woody get back to Sunnyside. He was later being played with by Andy and Bonnie and the other toys and was used as a horse for Buzz Lightyear while Jessie was riding Bullseye. He was last seen when Woody introduces him to Buzz, Jessie, Hamm, Rex, Bullseye, Slinky Dog, Mr and Mrs Potato head. In credits, he was seen hanging out with Andy's toys in Bonnie's room, while Buzz and Jessie were dancing.
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 then informs the cowboy about how dangerous Lotso is at Sunnyside Daycare and helps Woody escape from Bonnie's house to rescue his friends.
In 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 Daycare 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.
From Official Website:
- "Saddle up for fun and let Buttercup lead your child away on a magical adventure! This cuddly unicorn features velvety-soft, snow-covered fur with sparkly gold and pink accents. He sports a signature mythical golden horn and a fun-to-comb mane and tail. Buttercup's durably plastic eyes are both charming and scratch-resistant. Hypo-allergenic. Ages 3 and up."
- At one point in the movie, Buttercup calls Mr. Pricklepants "Baron Von Shush." This is because Mr. Pricklepants kept cutting Woody off by shushing him. To which Buttercup replies, "The guy's just asking a question!"
- Buttercup was originally going to be part of Lotso's Gang as seen in some Toy Story 3 concept sketches.
