Plump the Cow, Baby Bear and Willy the Worry Worm may only be animals, but they learn lessons just like any person--even if it means a few disappointments, briar scratches, or frights along the way. All God's Creatures Great and Very Small uses even God's smallest creations--like the nervous Willy the Worry Worm--to teach about the world he made and why it's important to help others, obey our parents, and be thankful.
