When Leo forgets his brand new toy dinosaur in the park, Daddy and Caillou go looking for it, with no success. So Caillou, with Mommy's help, puts up a Lost and Found Poster, and then, finds 'Dino' at the Park Office Lost and Found! When the washing machine needs fixing, Caillou ends up helping Bob the repairman. Inspired, Caillou helps Dad hammer a nail and glue the leg onto a wobbly stool too! Caillou accompanies Grandma to the Senior's residence where he finds out 'driving' the meal cart is more fun than driving his toy truck. Caillou even helps push Mrs. Wilson around in her wheelchair, proving to be the best driver she's ever had! When Sarah asks to borrow Caillou's wagon for her new paper route, Caillou offers to help too! Caillou, with Daddy's help, learns about getting up early, folding the papers and delivering them too. When Mom drives Sarah to her skating lesson, Caillou decides he wants to take skating lessons too!
