Grandpa tells Caillou about the time he went camping with Caillou's daddy a long time ago. Caillou wants to go camping with Grandpa too, so they set up the tent in the backyard. That night, Caillou and Grandpa cook marshmallows and look up at the stars. When it's time to sleep, Caillou finds it too noisy and a bit scary. The next morning, Mommy is very surprised by where she finds the campers.
