Meet the Garbage Pail Kids-Adam Bomb, Babbling Brooke, Brainy Janey, Cranky Frankie, Handy Sandy, Junkfood John, Luke Puke, Nervous Rex, Rob Slob, and Wacky Jackie. You may think they're gross and weird and slobby and strange, but they're not bad kids-they just don't know any better. Even though they all live together in one big tumbledown house and have as much fun as they can while trying to survive Smellville Middle School, they are pretty "normal"...

After being put back to sleep and abandoned in an old museum, Slappy is brought to life by a curious girl on a school trip. Out for revenge, Slappy uses his powers to raise an army of creatures from the exhibits. But when the museum closes, Slappy and his new friends are locked inside with Arragatis, an ancient mummy with his own plan for revenge. It's dummy versus mummy as Slappy faces his most dangerous and frightening opponent yet! Can Slappy defeat...
