S4·E24 Caillou's Castle
Aired March 10, 2006
Synopsis
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.
