Jessie (Joan Cusack) entered the world of Toy Story in Toy Story 2.
Jessie was a toy created based on a television program called Woody’s Roundup that starred Woody, Jessie, Stinky Pete the Prospector (Kelsey Grammer), and Bullseye.
Maybe the puppets are based on real people, like maybe Jessie was based on the creator’s daughter or something of that nature.
We could see the inspiration for the toy Jessie’s story in a movie.
