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. An hourglass is a reminder of how he defended the treasure in King Tut's tomb from raiders. A long white scarf inspires the story about Grandpa's dogfight with the notorious Red Baron, the great First World War fighter pilot. A coconut shell heralds the story about his encounter with a nasty Tyrannosaurus Rex. 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? How can his grandpa convince him that all you need to do is believe and a dream can be turned into something real?
