The Goo Monster leaves the Rickless Universe via the dying powers of a portal gun. It arrives in a parallel universe and violently kills its fun-loving Rick. The Goo Monster is apparently able to move through universes, as it follows the dead-Rick’s Morty and kills him, too. It is not known what happens to the Goo Monster at this.
