But a hat named Cappy grabs a piece, and he flies to Mario to team up with him. Cappy uses the piece to look like Mario's old cap. The two go and collect Power Moons, and in the Cascade Kingdom, they find a ship, named "Odyssey," making it work with Power Moons. The two climb aboard and chase Bowser, as they travel to various kingdoms. They fight bosses along the way and collect Power Moons to reach more areas.
