Turtles of Grayskull[]
Upon learning that something had activated the paradimensional alarm, Teela and Roboto rush to Man-At-Arms' workshop to inform him and He-Man. The disruption point is the Swamp of Gangoon and He-Man takes Moss Man and Ram Man with him to investigate. When they do not return, Teela, Man-At-Arms and Roboto head to the swamp to find them. They are set upon by Mousers and Mouse-Jaw. Just as the robotic horde is about to overwhelm them, the Turtles arrive to lend a hand. After defeating the Mousers and trapping Mouse-Jaw, the group goes back to the Palace of Eternos. There, Michelangelo introduces the Eternians to pizza, while Donatello outfits Teela and Man-At-Arms with new shell armor. By The Power of PIZZA!
