Luigi's is thrilled to find out he's won a new mansion (but also confused as he never entered a competition to win one). After sharing the news to Mario and his friends they agree to go to his new house so they can throw a party for him. When Luigi arrives he finds the mansion to be much spookier than he was expecting. It get's even scarier when he finds actual ghosts in the house. He is saved by Professor E. Gadd who informs Luigi that the Mansion is haunted and his friends and brother have been kidnapped by King Boo. It's up to Luigi to save the day. Just one problem, he's terrified of ghosts!
