This is a wonderful, colorful tale about a little boy named Zachary who loves to sleep with his favorite blankie and his favorite thumb in his mouth. One night, he decides to take his thumb out of his mouth and leave his bedroom for a magical world filled with animals and green forests and blue seas. He looks to see which animals suck their thumbs like him only to discover that many animals do not even have thumbs. He finally realizes all the important things he does with his thumbs and fingers besides sucking on them in his mouth. It's a great excuse for parents to act out the characters of the various animals while reading aloud.
