Master Shake (a milkshake that enjoys slacking off), Frylock (a pack of fries who is the teams voice of reason), and Meatwad (an infantile, shape-shifting meatball who is always curious) are fast food items that live New Jersey. One day, Shake buys an exercising machine called the Insane-O-Flex that, in actuality, is a piece of equipment that could pose a threat to the world. When their neighbor Carl tries it out, he finds himself stuck to it, and the machine morphs into a rampaging robot that buffs him up. With a villainous watermelon heading to Earth to claim it, as well as the evil Plutonians, the Force must team up with the Cybernetic Ghost of Christmas Past, and two bumbling aliens, to make sure no harm comes to Jersey.
