What does Jessi from Toy Story look like?

There's no character named "Jessi" in the Toy Story franchise. Perhaps you're thinking of Jessie, the cowgirl doll who is Woody's best friend and a major character in Toy Story 2?

Jessie is a red-haired, rosy-cheeked cowgirl doll. She has big brown eyes, a warm smile, and wears a pink and yellow dress with a red bandana around her neck. She also has a trusty sidekick, a horse named Bullseye.

Is there anything else you'd like to know about Jessie?
