"Just Desserts" Arthur has a hard time resisting sweets, and one evening his overindulgence wins him an upset stomach and a series of rather "Grimm" dreams_ starring Mr. Ratburn as a child-eating witch, the Tibbles as seven dwarves, and a fearsome giant made entirely of food! "The Big Dig" Arthur and D.W. used to love it when Grandpa Dave came to visit _ but now he only wants to sleep and play checkers. Then one day Grandpa Dave shares a secret map, and Arthur and D.W. hunt for a buried treasure and discover some family history.
