Drawn from the popular animated television series, the Clubhouse books follow Caillou as he continues to explore the world around him and gain a better understanding of his environment. Caillou prepares for a shopping trip with Mommy and finds so many distractions that they may never leave the house. When they're finally ready, the rain has stopped, and to Caillou's delight there are lots of puddles to splash in on the way to the store.
