Little Beaver is feeling scared ... his big front tooth is loose and feels as if it might fall out! How can he be a beaver without his big front tooth? Worried that he may not even be a beaver at all, Little Beaver heads off in search of his true identity, meeting LOTS of different animals along the way. "Am I a muskrat?" he asks and the Muskrat answers "No" - muskrats eat fish whereas Little Beaver eats bark. Maybe he's a porcupine? Or a woodchuck? In the end, it takes the kind words of Wise Old Beaver for Little Beaver to discover who he truly is and that losing your teeth is simply part and parcel of growing up!
