WHEN ARTHUR AND D.W. travel to New York City with their parents, they visit the Statue of Liberty, a museum, and they even see a Broadway show! But D.W. is most excited about visiting Mary Moo-Cow Palace with her Mary Moo-Cow doll. When D.W. doesn’t follow her parents’ rule and goes off by herself, the family must find her. Luckily, Arthur knows just where to find D.W.—Mary Moo-Cow Palace, of course!
