Following a particularly messy case, the Super Sleuths find that their scooters need a good cleaning. With the scooters out of commission for the time being, Pooh and Tigger substitute bicycles. Both are very fast on them, but Darby's still using training wheels. She'd like to be able to go as fast as the others, but is scared that she's going to fall. Turtle Comes Out of His Shell: Turtle decides that the doesn't need his shell anymore-- it's only getting in his way. He calls upon the Super Sleuths to help him find fun new shell-free activities to do. When he finds that he can no longer hug Porcupine, he begins to wonder if his decision might have been a rash one.
