The Fungal Forest is a place in the magical world of Wonderland in Lewis Carroll's Alice in Wonderland. In Carroll's story, Alice meets the Caterpillar there. In Beyond the Kingdoms, Alex, Conner, the Tin Woodman, Peter Pan, Mother Goose, and Lester travel into the story in order to stop the Masked Man. Like Alice, they meet the hookah smoking Caterpillar in the forest of mushrooms, who (in very riddled terms) tells them where to go.
