In the Cat's Playhouse, Terrence McBird is cranky because he refuses to take a "cat nap." Will the Cat, Sam-I-Am and the Little Cats be able to help? In the Wubbulous World, Sarah Hall-Small encounters the scary-looking Yapper-Nap, who frightens everyone in Seussville, but he's actually just sleepy. We also see what our friends in the Wubbulous World dream about.
