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.

In addition, he also built two machines to help give him the edge in the Spikers League, one being a rocket-powered scooter and the other being a backpack with several mechanical hands. 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. The backpack resembles F.L.U.D.D.'s head, and its arms resemble the following; a blue pair of scissor blades, a green glove, a red boxing glove, a mechanical claw hand, and a head almost identical to F.L.U.D.D.
