In the land of Animalia, every kind of animal has its town-and incredible music. But the beat takes a dangerous turn when the famous Eight Cool Cats are kidnapped by a sneaky dog manager named Ruffa Puffertwight. Ruffa has a big problem: he wants to win the brand-new Super Band Competition in Birdheights, where mixed-animal bands aren't allowed. His "brilliant" (and terrible) idea? Kidnap the cats' mothers with sleepy-time milk and force the kittens to hide in dog costumes so they can play in his not-so-great dog band.Now the Cool Cats are stuck on a wild road trip to the contest, trying to hide their secret tails, dodge disaster, and figure out how to save their mommies. With every song they play, the risk of being found out grows, and so does the chance to turn Ruffa's scheme upside down.
