Roo can't seem to teach Lumpy to ski, so he calls the Super Sleuths for help. The Sleuths come up with a number of ideas that seem to be helpful at first, but Lumpy still fails when it comes to skiing. Lumpy is ready to give up, but then his Mama Heffalump appears and urges him to wear his scarf. Lumpy gets the idea that it's a magic scarf that will help him to be a great skier. Darby's Squirmy Worms: When Rabbit discovers that his garden is full of worms, he treats them as a hostile invasion force. He calls the Super Sleuths to remove them. The Sleuths agree, even though they aren't sure just what harm the worms are to Rabbit's garden. When they succeed in removing them, Rabbit's garden only seems to get worse and they realize they'll have to think, think, think harder to solve the problem.
