Two Headed Duck

The Two-Headed Ducks are animals that appear outside of the Tree Fort in the "Adventure Time Theme Song" and in various episodes. It may have been mutated by The Great Mushroom War that befell the post-apocalyptic Land of Ooo.

One can also be seen in the episode "The Witch's Garden" outside of the Tree Fort and in "Her Parents," multiple two-headed ducks appear, suggesting they are a species. Because two-headed ducks can only be seen around the Tree Fort, it can be assumed that they live there or have a nest somewhere nearby. It seems to only be seen in the background. It is also seen in "Holly Jolly Secrets Part II," during the annual party Finn and Jake host. Jake is seen holding it.
