Today is full of adventure! Caillou, Daddy, and Rosie take the car to the carwash, which is scary for Rosie at first. But big brother Caillou explains everything to his sister, who winds up liking the carwash too! Caillou, Rosie, and their babysitter Julie travel to a bunch of pretend far away places like the desert, a big mountain, and even waterfalls in the tropical forest. Caillou doesn't go to school yet but he really wants to ride on the school bus that stops outside his house every morning. When Dad takes him to see the bus from close up, the driver offers to take Caillou with the other children the next day. On another day, Caillou and his family have a wonderful day out at a theme park. Caillou and Dad go on the thrilling Niagara River Ride, they all go on a Ferris wheel and for a special treat they have cotton candy for dessert. When the house wakes up late, it's a mad rush to get Mommy off to work. Later, when Caillou goes for a walk with Daddy he meets all kinds of people doing all kinds of jobs--and he gets to try being a mailman, a sanitation engineer and a policeman for himself.
