Cowbella does not want to go to sleep because she is worried that everyone is having fun without her after bedtime. When the Pajanimals visit Mr. Moon, he takes them around town to show Cowbella that everyone is sleeping safe and sound in their beds, and she sees that she is not missing out on anything at all. And it is learned that sleep allows the Pajanimals to regain their energy so they can have fun tomorrow! This interactive lift-the-flap book includes flaps on every spread and is perfect for little hands!
