The speedy super-villain CHAUNCEY THE CHEETAH is loose on PARADISE ISLAND! However, WONDER WOMAN'S SUPER-PET, JUMPA THE KANGA, isn't worried. This blazing-fast bouncer is the quickest critter on Earth. Or is she? When CHAUNCEY challenges JUMPA to a race, the kangaroo must prove her swiftness and her cleverness. But this criminal cat is chasing more than bragging rights. She's seeking JUMPA'S tiara as top prize. If JUMPA doesn't have a few tricks in her pouch, she might lose in more ways than one.
