Luigi decides to go swimming, and jumps off of the Tree Fort and into the pond. After swimming for a little bit, LuigiMario112 wrings him out and takes him back into the house and puts him in the Tunnel of Time, which will make time go backwards and cause Luigi to be dry again.
Mario wakes up, and sees Jack Skellington dancing. After a conversation, Mario takes Jack to meet Luigi, but Luigi is scared of him. Jack tells Luigi that if he thinks he is scary, he doesn't want to see his girlfriend, Sally, who was kidnapped. Jack shows them a plan that he made on how to defeat the person who kidnapped her, Bowser. Mario doesn't like the plan and comes up with a new one, but Bowser listens in on them.
However, Jack fell asleep while Mario was talking, and out of frustration, Mario throws him into the washing machine. They leave him behind, but Bowser shows up and kidnaps Jack too.
In the living room, Mario and Luigi are playing Super Paper Mario. Bowser arrives with Jack in his bag, and Mario, Luigi, and Bowser then fight. Mario uses his special move, gets a huge boxing glove, and then punches Bowser away with it. Then Luigi uses his special move, Irish dancing. Bowser claims it didn't hurt, and uses his special move, fire breath, which both the Bros. dodge. Mario rescues Jack, and then Luigi claims to have found Sally, but it turns out to be Toad. Jack realizes that Bowser never kidnapped Sally at all, and realizes that she was back at Halloweentown the whole time. He bids the Bros. farewell and leaves saying he hopes to see them again, but is shot down by someone behind a bush. Four years pass, and the Mario Bros. never find Jack.
