18. Horton Has a Hit When Yertle the Turtle hears Horton the Elephant singing a lullaby to Morton the Elephant Bird, he knows that Horton has what it takes to make it to the top (and to take Yertle with him). Horton must leave the suddenly popular Morton and his new 'friends' in the care of his Uncle Norton as he goes on tour. Is all the fame and fortune worth it? 19. The Birthday Moose Thidwick the Moose is so excited. It's his birthday, and just like every other year, the Birthday Bird will take him (and all of the other birthday celebrants) to Katroo for a huge party. But when word comes that the Birthday Bird is unable to make it this year, Thidwick decides to take charge and lead everyone to Katroo himself... disguised as the Birthday Bird! 20. The Grinch Meets His Max / Halfway Home To Malamaroo The Cat in the Hat has left Little Cats A, B and C alone with a nifty storytelling machine, and when they insert a backscratcher, they hear the story of how The Grinch and his dog, Max, came to be friends when the Grinch has a very irritating itch on his back. When they insert a half-eaten cake, they are told the story of Alvin, an alien from Malamaroo. Alvin is as sweet as can be, but he drives Jane, Junior and Thidwick the Moose crazy when he never finishes what he starts including his trip home! 21 The Cat in the Hat Takes A Nap 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 (all but Sarah), but he's actually just sleepy. We also see what our friends in the Wubbulous World dream about. 22 The Cat in the Hat Cleans Up His Act In the very messy Cat's Playhouse, when the Cat in the Hat loses his bow tie, it's cleaning time! That is, if he and the Little Cats ever get around to it... In the Wubbulous World, we meet Matthew Katroom, who battles his messy room. And Yertle the Turtle sells Jane Kangaroo a new kind of mess-free Turtle Tree, that doesn't drop any leaves.
