When Mario is about to face off against King Boo and reclaim Cappy, whom the ghost king stole, he notices Gadd in a painting. He is freed from the painting when King Boo is defeated, and he stays around the mansion after that point to run his minigame, 'Boohunter', in which the player catches ghosts using a new Poltergust model in a Luigi's Mansion-esque challenge.

The scooter is red and has roller blades, as well as a nozzle similar to the Poltergust 5000 that serves as a rocket thruster to boost it forward.
