Gary the Gadget Guy discovers his long lost uncle's mansion has appeared in the Forest, and he wants us to help find his great uncle, Gariwald VIII. Gary leads ghost hunters into the mansion. They discover the Ghost Lab and Gariwald as a ghost. Gary discovers that his great uncle didn't pass away and become a ghost, but rather became one on purpose, using his Ghostamatron. Penguins soon started to use Gariwald's invention to transform themselves into ghosts to haunt the island.
