Curious George Goes to a Chocolate Factory 

George is monkeying around—and having a delicious adventure!   When George and the man with the yellow hat stop to shop at a chocolate factory store, George becomes curious about how the chocolates are made. Though he begins to follow the factory tour, soon he is off to investigate on his own…   “The only predictable thing about that dynamic monkey, Curious George, is his unpredictability.”—The New York Times
