The Grinch Meets His Max / Halfway Home To Malamaroo - S1.E20

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 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 crazy when he never finishes what he starts -- including his trip home!
