"Foodfight!" takes place in the supermarket at night when the kights go out and all the people leave. Then, magically, the grocery store transforms into a city: the boxes become buildings, the asles turn into streets. The Chinese food aisle becomes China Town, the Italian food aisle becoming Venice, and so on. Then out from every door of this 'marketropolis' comes two types of characters: ones you already know - some of the most famous characters in the world, like Mr. Clean, Charlie the Tuna, the Energizer Bunny and more; and ones you are going to meet, and the actual stars of the movie. These include Dex Dogtective (Charlie Sheen), the super sleuth and the head of the USDA (United Supermarket Defense Association); Daredevil Dan (Wayne Brady), the world's worst flying squirrel stuntman; the sweet and lovable Sunshine Goodness (Hilary Duff); and the villainess and the seductive Lady X (Eva Longoria). They all hang out at the Copa-Banana, the hottest nightclub in town (in the produce section of course). However, all's well until Brand X moves into town and its avil LADY X and her minions try to take over.

The only way to stop them is...yes...A Foodfight!
