Caillou, Rosie and Mom are having fun at the park when the ice-cream man comes around. Caillou wants an ice-cream but the ice-cream man leaves before he can get there. Caillou is very frustrated and complains to Dad when they get home. Dad has an idea and Caillou cools off by riding his bicycle. When Caillou rings his bicycle bell, Dad suggests Caillou be the ice-cream man! Caillou is delighted by the idea. Soon, lots of “customers” join him in the kitchen to get one of his unique ice-cream creations.
