The Mutant Coyotes are a species of coyotes that appear during a flashback in the Adventure Time: Distant Lands episode, "Obsidian". In the episode, a young Marceline spots a child coyote and begins to pet it, referring to it as a puppy. Once her mom sees its disfigured face, she kicked it to the side, which angers an older coyote that was watching from a ledge. It howls and begins to attack, but Marceline sucks its soul out. The younger coyote is seen curling up beside its soul-sucked companion before the scene changes.
