Mama Bear is all set to give the tree house a good spring-cleaning. Papa Bear, Brother Bear, and Sister Bear all offer to help. They start to clean the house from top to bottom, collecting things for a yard sale along the way. A cracked lamp, a split bat, a broken fishing pole, a torn teddy bear, and other tattered things are all to be put on sale. But each tattered thing seems to be someone's favorite! Perhaps spring-cleaning will have to wait until next year.
