The Mooninite's steal a giant orange check from Ignignokt's Uncle Cliff and got to Earth to spend it. They stop by the Teens' house to get their check cashed, but because the Teens have so little money, the Mooninites got to a convenience store with Shake and Meatwad to get it cashed. Even though the store manager says they don't cash checks, especially not those kind, the group keeps trying to get him to cash it. But is it really a check or is it something else?
