Things that go bump in the night, and others that light up the sky, are on everyone’s mind today. A family corn roast dinner at Grandma and Grandpa’s under the star-studded sky prompts Grandpa to bring out his telescope and introduce Caillou to the constellations, planets, and moon. But fun turns to fear at bedtime when Caillou decides that a monster is lurking in his room. Maybe he’s picked up the puppets’ jitters; their own night under the stars convinces Rexy that a monster’s hovering over them! All’s well when Mom and Dad unmask Caillou’s monster as a tree branch on the window, and Rexy’s one-eyed monster turns out to be the shimmering moon! Puppet segment: Teddy and Rexy get left outside by mistake, and mistakes a moon for a monster and tries to run from it - until Gilbert comes along and corrects them, then take them indoors. “Star Light, Star Bright” Caillou's grandma is making her special top potato sald which Caillou says it's "Yummy!" Caillou's family looks up at the beautiful night sky. It reminds his daddy of when he used to look for shooting stars. Caillou really wants to see a shooting star for himself. While Caillou and his daddy look at the moon and several star constallations, Caillou tries being patient to watch a shooting star going by. “Caillou in Space” Leo has brought a new toy rocket, and he and Caillou pretend to be astronauts traveling to the moon. Caillou's daddy reads in the newspaper that a new planetarium is opening, and they're holding a contest for the best space costume.
