Turtles of Grayskull[]
After He-Man, Ram Man and Moss Man go missing in the Swamp of Gangoon, Man-At-Arms, Teela and Roboto investigate. Though Roboto’s scanners show no sign of their missing comrades, they do pick up strange signals which he guesses might be an unidentified life form. Man-At-Arms discovers a strange purple substance dripping nearby, wondering aloud as to the origin of what appears to be some sort of cross-dimensional mutagen. Teela suddenly shouts at her father to look out and he moves quickly as the mutated Trap Jaw lunges at him. Roboto says that the being matches the strange signal, but he is not Trap Jaw. He is now Mouse-Jaw, and he is accompanied by a horde of Mousers. Just when the heroes are about to be overwhelmed, the Ninja Turtles arrive. The Mousers are defeated and Mouse-Jaw is captured.
