It is Halloween at the Tipton. When looking for Arwin, Zack and Cody accidentally release a robot Frankenstein monster (created by Arwin), who is almost an exact replica of Arwin. The employees think 'Arwinstein' is Arwin in his costume for Halloween. Meanwhile, London is hosting a Halloween party at the Tipton, which has a costume contest, and the winner gets diamonds. Arwinstein shows up at the party and becomes the winner of London's costume contest. Soon, Arwinstein kidnaps Carey and everyone finds out that Arwinstein is a monster.
