Anybody Home?

Polly 'Possum is looking for a new home to raise her expected babies. Along the way, she meets a wide variety of diurnal and nocturnal animals. She learns how they build and live in webs, nests, hives, shells, burrows, lodges, dens, caves, dreys, and even hollows. While those homes are perfect for those animals, they aren't right for her. How does Polly find a home and will she find it in time?
