S2·E38 Drum Di Drum

Nick and Sally are trying to make some music, but they need drums. What about the drums in your ears? asks the Cat. Drums in ears?? Dr. Giggles will teach them all about it! By shrinking down super small, they go inside Thing One's ear to explore. They get to the ear drum and learn that it's not for making sounds, but for catching them! Back at home they play their music, and thank their ear drums for being able to hear it!
