Cosmic Owl

Cosmic Owl is a creature that appeared in "Prisoners of Love" in Ice King's Imagination Zone, when he was knocked out by Finn. When Ice King contemplates why people do not like him, the Cosmic Owl answers, "You're a sociopath." It is unknown if the owl is evil, good, or neutral.

The Cosmic Owl then makes an appearance in the episode "Donny" as a drawing. The Cosmic Owl will eat the Why-wolves once their population grows.

In the episode "The real you" the Cosmic Owl seems to be carved into the chairs in the library.

Trivia

 * The Cosmic Owl's design is based on the lighting above a urinal at Cartoon Network Studios.
 * In the episode "Donny," the Why-Wolves reveal this owl to be the "Cosmic Owl," which is destined to someday devour them.
 * It is possible that the Cosmic Owl is the 'god' of The Land of Ooo, and has the sole purpose of keeping balance. This would explain why he would eat the Why-Wolves if their population grew.
 * His voice resembles the voice of Dr. Phil McGraw.
 * In the episode "The Real You", in the top rail of the library chair there was a graven image of an owl with emerald eyes, possibly the Cosmic Owl. This may suggest that the Cosmic Owl is a god of knowledge.
