When he first appeared, Stinky Pete was initially a kind, wise, well-spoken, and grandfatherly mentor-like character, giving support and advice to Woody, Jessie, and Bullseye throughout the first half of the film. After he met Jessie and Bullseye, Stinky Pete befriended them while they waited for Woody. However, Al learned that the museum wanted the entire Woody's Roundup Gang toys and went to collect them all, so Stinky Pete had to wait. Stinky Pete found this to be good news, if kids didn't want him, they can't have him once they change their minds. Since Al was grown up, he planned to sell Stinky Pete to a toy museum in Tokyo.

He was later sold to Al McWhiggin, who never took him out of the box for unknown reasons, which made him even more insane and angrier. Stinky Pete was never bought or played with by a child and spent a lifetime on a dime-store shelf, watching every other toy be sold to their new owners, which caused him to grow bitter, selfish, and angry.
