Oh, Bother! Someone's Messy! — Betty G. Birney

This is one of the appealing titles in a special Pooh series that addresses -- and resolves -- simple childhood problems. This time the problem is Roo's messy room. Roo thinks cleaning things up is just too much trouble. But one day his mud pies get too messy, and no one will come over to play. Roo is about to change his ways -- thanks to the help of a few loving friends.
