In it, someone unknown to me used the Dragon Balls to summon the One Ring from Lord of the Rings into a Mario Kart game, and suddenly Waluigi, Mario, Wario, and several others which I am currently having problems identifying since dreams disappear from memory so quickly got into a comical chase scene (with vehicles and Mario Kart power-ups) all trying to collect the ring and flee the stage with it. I think Wario won, but only because he had it when I woke up.
It was hilarious.
