What could be more boring for a little kid than being stuck in the house on a rainy day with nothing to do? Luckily Caillou has a very inventive friend, Julie, who helps open up his world by introducing him and the audience to the joys of reading books. Caillou and his friends Sarah, Clementine, Leo and his best friend Gilbert the Cat, all participate in the adventure by bringing their favorite books to the stage. Everything from a Joke Book, to the ABC's, to a Pirate Adventure and much more, all come out of the Giant Magical Book that Julie brings with her. Along with learning that reading is fun, the audience gets to sing, dance and participate in every aspect of this fast paced production.
