Mortimer Mouse needs a new house -- a house that's not so cold, cramped, and dark. Where can he go? He sees a huge tree covered with twinkling lights. And next to the tree, a mouse-size house. And inside the house, a wee wooden manger just Mortimer's size. But statue people seem to already live there! One by one, Mortimer lugs and tugs the statues out of the house -- only to find them all put back in their places each evening! What is Mortimer to do?
