Show and Tell - Caillou has to decide on a nice surprise to bring to playschool for Show and Tell. The only problem is, he can't decide between his toy dinosaur Rexy, his kite, or his toy firetruck. However, when Rosie proves to be the best at surprising everyone, Caillou decides to bring his little sister for Show and Tell. Caillou the Magician - Grandma shows Caillou a simple magic trick, which makes him decide to be a magician. After finding a suitable costume, he practices a new trick - making Rosie disappear! When the time comes to show Mommy and Daddy their trick, Caillou finds that making Rosie reappear might be a challenge, especially when Gilbert gets in the way! Caillou's Castle - Caillou wants to play castles and dragons, even though Gilbert isn't very keen on playing the dragon. Mommy asks him to share and play nicely with his sister, so Caillou and Rosie build their very own castle out of empty cardboard boxes. When Gilbert doesn't want to be the dragon, Mommy and Daddy volunteer for the part and everyone has lots of fun playing make believe.
