| Character Information
Mushroom is a minor character in The Amazing World of Gumball. Like Hot Dog Guy, he usually appears in the background of the school cafeteria, usually sitting around other background characters. His first appearance was in "The Third." He also appeared in "The Flower" behind Gumball before Carrie takes him to her house. He also appeared in "The Name" in the cafeteria once again. Then, he appears in "The Extras," which is his first speaking role in the show. He's seen singing angrily along with the other background characters towards Gumball and Darwin.
Mushroom has a tan cap with white spots, and a purple colored stem in Seasons 1 and 2. In Season 3, he has a pink cap with white spots, and a tan stem, with pink hands and legs. However, he reverted to his old design in "The Mirror", but got his new design back as of "The Butterfly".
