SpongeBob, Jimmy, Timmy and B.O.B. build a rocket to go to the moon after being annoyed by Sheen and the others too much. However, thanks to a miscalculation made by Jimmy (who later says he "Forgot to carry the two"), they end up on top of a building with a cat named Max trying to catch birds for food. Meanwhile, Sheen and the others deal with the booby traps in SpongeBob, Jimmy, Timmy and B.O.B.'s HQ while trying to "borrow" their TV. When SpongeBob, Jimmy, Timmy and B.O.B. return and discover this occurring, Timmy wishes up a hammer for SpongeBob, who declares "Operation: Hammerhead" in retaliation.
