Bo Peep’s shepherdess figurine in Pixar’s Toy Story films is made from porcelain.
Bo Peep is based on the traditional nursery-rhyme character Little Bo-Peep, but Pixar reimagines her as a porcelain lamp figurine who can move independently when humans are absent. Her delicate material is part of her visual identity and helps distinguish her from mass-produced plastic action figures such as Buzz Lightyear.
Bo Peep appears as Woody’s close friend in the first two Toy Story films. She is absent from most of Toy Story 3, with the story explaining that she was given away before the events of that film. Toy Story 4 later reveals her life as a “lost toy” and develops her into a more independent adventurer.
Porcelain is sometimes confused with ceramic, because porcelain is a type of ceramic material. The more specific canonical answer for Bo Peep’s figurine is porcelain, not ordinary ceramic or plastic.
