Callie the Caterpillar is a happy, friendly little bug with a very large problem: Callie is afraid of the dark. Her fear of the dark has not been a problem before because she lives under a large floodlight. However, when Callie discovers she must spin a cocoon (and everyone knows cocoons do not have nightlights ), Callie embarks on a quest to learn how to conquer her fears. With the help of her two friends, Mrs. Goat and Mouse, Callie learns a bit about courage, a little about what she was created to do, and a lot about friendship.
