Cappy (referred as Crappy by Mario) is a character from the recently released Nintendo Switch game Super Mario Odyssey. In SMG4, he appears in Stupid Mario Odyssey. Mario had lost his original hat so he went to the store to find a new one and came across an identical hat which turned out to be Cappy. Throughout the video, Mario is helping Cappy get back home while fighting monsters such as dinosaurs along the way. He reappears in Stupid Mario Odyssey 2 to save his sister Tiara.
