There's a disturbing scene in The Amazing World of Gumball which has Gumball and Darwin taking a serum that mutates their bodies. The result of it causes Darwin's body to mutate into a strange tree with mushrooms sprouting out of it. In the same episode, the titular character sells one of the student's parents to a clown which proceeds to turn the kid's parents into balloon animals.
