Today Kit and Pup are exploring the opposites Light and Dark. They start by going camping. Pup is trying to sleep in the dark but excitable Kit keeps turning on the light. Kit and Pup then try to find as many light and dark places as they can. In the live-action investigation, Kit and Pup help the little investigators make shadows using torchlight. And in the stop-motion moment a young investigator is blowing out birthday candles, causing the room to go dark.
