Caillou and his daddy arrive at that park and Caillou goes to the playground and pretends that he is on train. Then, Clementine shows up and wants to go down the slide. Caillou slides down one of the small tubes, but Clementine wanted him to go down the big slide. Caillou doesn't want to, so he convinces Clementine to continue playing train with him. Soon, Clementine wants him to go down the slide. Caillou tries not to be afraid, but once he gets to the top he is very scared and tells his daddy to come up with him. Daddy convinces Caillou to slide and they go down together. Clementine isn't impressed that Caillou was so scared. So Caillou goes down the slide alone. It is then time to go home, but Caillou asks his daddy if he can do it on more time. Caillou ends up having so much time that he ends up sliding many times before he and Clementine are finally ready to go.
