"Caillou Plays the Drums" - Caillou is over at Clementine's house playing dress-up. Suddenly, he hears a loud banging sound. Clementine explains that it's her brother Billy playing the drums. She and Caillou head over to his room to check it out. Billy explains to Caillou that he's learning how to play the drums so he can be in a rock band. Caillou notices pictures of rockers on the wall of Billy's room and comments on their funny clothing. Billy, though, doesn't think the clothes are funny, but Clementine admits to Caillou that she finds them funny too. They ask Billy if it would be possible for them to try out the drums. He says that they can't --- they're too little, and drums are for grown-ups, not for little children. Caillou and Clementine aren't happy with this dismissal. They don't think they're that little and they decide that they need to do something to show Billy that they're old enough to play the drums. They decide to make Billy a snack. They get him a sandwich and milk and Clementine has her Mom cut the crusts off the bread, as she knows Billy doesn't like them. They take the snack to Billy. He thanks them for it, but still won't let them play the drums. Their next idea is to dress up as adults, using clothing from Clementine's dress-up chest. Billy, naturally, doesn't believe that they're actually grown-ups, but, apparently amused, he does give in. Clementine says that Caillou can go first, since dressing up was his idea. Billy shows him three different types of drums ---a bass drum, a snare drum and a cymbal. Caillou really enjoys the sound of the cymbal. He fantasizes that he's playing on-stage as part of a real rock band. Mommy arrives to pick Caillou up. He's still dressed in his "grown-up" clothes and tells her that he's all grown-up.
