Growing up is not so tough — especially with a friend like Caillou (pronounced KY-YOO), a lovable four-year-old who has a unique way of relating to the world. Based on a series of best-selling Canadian children's books, Caillou demonstrates how the first experiences of life, from going to the park to understanding one's own family, can be perceived with wonder and a sense of discovery. Blending animation and live-action segments with humor, kid logic and imagination, Caillou helps preschoolers make sense of the world. The stories address real problems and conflicts typical to a young child's development. Through it all, Caillou remains an irresistible little boy in a very big world, with whom every young child and parent can identify.
