Vampires and werewolves and zombies - oh my! It's a monster invasion, and the stinky-smelling creatures are destroying Wally's peaceful little town. They scare the kids, knock over the lampposts, and make a mess of everything. And no one can stop them - until, fed up, Wally says the magic word, "Please." Learning good manners has never been as monstrously fun!
