Caillou and the family are at Grandma & Grandpa's for an evening corn roast. Everyone marvels at the night sky full of stars-which gives Grandpa the perfect opportunity to bring out his telescope & introduce Caillou to the constellations. // The house wakes up late, and that means it's mad rush to get off to work and off to childcare. When Caillou doesn't want daddy to go to work, dad decides to show Caillou lots of people at work in their neighbourhood. Caillou meets all kinds of people doing all kinds of jobs. The best part? When he makes the light and siren go off in the police car! // It's time for Gilbert's annual visit to the Vet. Gilbert instinctively know where he's heading. He hates riding in the car, so Caillou does his best to comfort him-with near-disastrous results! Things only get worse when Gilbert confronts a dog in the waiting room. The Vet suggests that Caillou could comfort him when he gets his shot. That wasn't so bad, was it? MEOW! // When Caillou plays astronauts with Leo he upsets Rosie. Meanwhile, Grandpa discovers a new panetarium is opening and there's a prize for the best space costume. Caillou is thrilled when the winner turns out to be…a surprise!
