Charlie loves when Grandpa comes to babysit because he always brings his magical imagination. Grandpa was a magician who knows the most amazing tricks; he can pull a rabbit from a hat and make a coin disappear. But what Charlie loves most are his wonderful adventure stories, and they all begin with something his grandfather has saved in his Magic Story Chest. Charlie's parents, though, aren't too sure they like Grandpa's stories and warn Charlie that they're just 'tall tales.' What is Charlie to believe?
