The little girl who receives Andy’s toys in Toy Story 3 is Bonnie.
Andy is preparing to leave for college, and his mother mistakenly places the bag containing his toys with items headed for donation. After the toys escape Sunnyside Daycare, Andy ultimately gives them to Bonnie, a young girl who lives nearby. Before leaving, he introduces each toy to her and watches as she begins to play with them.
Bonnie is not Andy’s sister Molly, another child connected to the Davis family. Molly is Andy’s younger sister, while Bonnie is a new owner who appears prominently at the end of the film. Bonnie’s mother works at Sunnyside Daycare, which helps connect Bonnie to the story earlier in the film.
Bonnie returns in Toy Story 4. On her first day of kindergarten, she makes Forky from a plastic spork and craft materials, giving the toys a new adventure. Her name is therefore tied not only to Andy’s farewell, but also to the franchise’s next generation of play.
