The next time we see the ghost, he's using his abilities to talk to the player next door. He wants to know if you're a ghost, and if you came with a water gun. Uh-oh. The water gun? Nope, it's just a toy. The player next to the ghost asks if the ghost can talk, and the ghost says he can. The two of them are going to have a three-man team-up to kill another team, and then they'll have a final duel.
