Come and join Caillou's party where he tries his hand at puppet theater and being a magician. One day at the park, he accidentally breaks Clementine's bucket, so Caillou offers his bucket to replace the broken one, and they all work together to build a sand castle. When Leo trips and falls, Caillou is worried that it may have been his fault. But Leo explains it was because he hadn't tied his shoelaces and Caillou feels much better.
