Three times, Finn attempts to experience the "cool" and "important" dream again because the Cosmic Owl is there. In " Frost & Fire," the Cosmic Owl appears in Finn's dreams, foretelling his inevitable break-up with Flame Princess. At first, he is disappointed that he and Prismo could not play board games like they planned to, but he does join Jake and Prismo in the pool party. He also appears in " Jake the Dog," visiting his friend Prismo in the Time Room inside the Multiverse while Jake is making his wish. The Cosmic Owl also appears in " The Lich," where he is seen in Finn's dream on a television screen, indicating that Finn is in a "premonition dream." The owl is also featured prominently on the episode's title card. He appears in " The New Frontier" at the end of Jake's " croak dream," and Finn and Jake's later conversation suggests that it is well known that the Cosmic Owl is supposed to show up in croak dreams. It is stated that the Why-wolves, if not stopped, would ravage the world and overpopulate until the Cosmic Owl would be forced to intervene by devouring them all, as is the course of nature. The Cosmic Owl again appears in the episode " Donny" as a drawing made by the Why-Wolf. When Ice King asks why people do not like him, the Cosmic Owl answers, "You're a sociopath." Ice king does not care and calls him a big nerd.

The owl first appears in " Prisoners of Love" in Ice King's Imagination Zone, after Ice King is knocked out by Finn.
