Character
Cosmic Owl
Cosmic Owl in Adventure Time: Fionna and Cake (2023), played by Frank Collison.
The Cosmic Owl is a cosmic entity known to the inhabitants of Ooo for appearing in Premonition dreams. He seemed to have a young, rural-type accent at first, but spoke with a voice like that of an elderly man from "Jake the Dog" onward. Initially mysterious, the episode "Hoots" revealed that he was a lonely individual.
