What is the name of the toy modeled after a potato in the Toy Story films?

The potato-shaped toy in the Toy Story films is Mr. Potato Head.

Mr. Potato Head is a Hasbro toy made from a potato-shaped body with detachable facial features and accessories. Pixar adapted the toy as a sarcastic, impatient character who can remove and replace parts of his face and body for comic effect.

In the films, Mr. Potato Head is married to Mrs. Potato Head and is part of Andy’s original group of toys. He often reacts skeptically to Woody’s plans, but he repeatedly participates in the group’s efforts to help one another. His removable parts are used for jokes and action scenes, including disguises and physical mishaps.

The character’s name refers to the commercial toy brand, not to a generic potato character invented for the film. Mr. Potato Head appeared in the original Toy Story and continued as a supporting character throughout the main series.
