"The Powerpuff Girls are going to the zoo. They are on a field trip with their class. But uh-oh... Mojo Jojo is there, too! He wants to steal a rar white tiger. Can Blossom, Bubbles, and Buttercup stop him?"--cover.
Halloween is here, and Blossom, Bubbles, and Buttercup can't wait to dress up and go trick-or-treating! When they hear the legend of the Shadow, a creepy creature that lives in a haunted house outside Townsville, the Girls know what they have to do -- kick some monster butt!
When a squirrel in the Girls' backyard gets an accidental dose of Chemical X, he becomes their new best friend/pet/mascot/partner in crime-fighting. The Girls are just crazy about the new member of their team, but will he miss his old nut-gathering ways too much to stick around?.
