Uncle amiibo is a sapient robotic character who debuts in Super Mario Odyssey. He travels with Hint Toad and provides exclusive abilities for amiibo in the game. He is always found near Odyssey's landing ground. He provides the locations of the Power Moons that the amiibo find, or provides a costume if certain amiibo are scanned. After using an amiibo to find a Power Moon, Mario must wait five minutes to retrieve the hint.
Mario is able to stand on Uncle amiibo just as on a platform, instead of bouncing on him repeatedly as it happens when Mario jumps on any other character.
