Just Desserts & The Big Dig

Just Desserts: Arthur has a stomachache after eating too many sweets and has dreams involving fairy tales made famous by the Brothers Grimm. Mr. Ratburn the Witch says "I'm melting" like the Wicked Witch of the West from The Wizard of Oz in 1939.
The Big Dig: Arthur and D.W. don't want to spend time with Grandpa Dave because all he does is play checkers and sleep. He tells them about a buried family treasure, but the two do not want to wait up for him so they take the map and look for the treasure themselves.
