Caillou Plays the Drums - Clementine's big brother Billy has a new drum set and is having lots of fun playing as loud as he can. He won't let Clementine and Caillou play his drums though, because he says they're not grown up enough. The two friends set out to prove him wrong, and once they put on their 'grownup costumes' he finally relents and lets them play. Caillou pretends he's a rock and roll drummer playing a big drum solo! Caillou's Marching Band - Caillou and his friends are very excited when a real marching band goes by the playschool. They decide they want to be in a marching band too. The kids find some makeshift instruments in the classroom, and Emma makes them matching band hats. After a shaky start, Caillou leads the others by beating on his drum and they march around the schoolyard like a real marching band. Caillou Sings - The playschool is having a talent show and Caillou wants to sing a song, but Clementine beats him to the punch, picking the exact song he wanted to sing. When it turns out she's having trouble remembering all the words, Caillou suggests they work together and the resulting song-and-dance routine is the hit of the show!
