It's a beautiful night to camp underneath the stars. After learning that Grandpa took Daddy on a camping trip when Daddy was Caillou's age, Grandpa and Caillou set up a tent in the garden. Then, while Caillou and his family are at his grandparents' house, everyone marvels at the beautiful nighttime sky. This gives Grandpa the perfect opportunity to let Caillou use his telescope. Plus, watch Caillou and his friends take a nature hike through the woods, go on a class trip to a butterfly conservatory, and lots more fun.
