Finn wishes for a human world, Len wishes for a cartoon world. When the two boys find out about each other (and realize how amazing it is that they look alike!) they decide to switch lives for a day. But once they do, they only cause more trouble. Will they be able to fix things up? Or will they stay in the opposite's worlds forever?

When Bubblegum mistaken the virus circuit as a chip for the Finn-bot 3000, It exploded and everyone in the land became robots, Even Finn and Jake.
