Joe and Blue teach the viewers about observing things carefully to learn more about them. For example, we look carefully at a duck to figure out what it's doing. They play a game called Mystery Box with Shovel, Pail, and Gopher. Later, we end up in a game show where observing things carefully could earn us big prizes, or not.
