Wayne Manor has been overrun! There are penguins in the tub and bunnies in the bedroom, penguins in the freezer and bunnies in the fridge, penguins and bunnies everywhere - they've even driven the bats out of the Batcave! Poor Robin is caught in the middle of the bunny-penguin turf war and has to figure out how everyone can live together peacefully! (PS. Did we mention the penguins and bunnies?)
