Slug wants to fly, but the idea of being ’born again’ as a butterfly frightens him. Like many other caterpillars, he wants to live his way. He is deceived into going to the center of the tree where disobedient caterpillars indulge in worldly activities.
Grunt, a crow, is flying with a gang. He wants to be accepted and look cool. The gang hunt foolish caterpillars who leave the safety of their leaves and go to the center of the tree. Grunt meets Grace who teaches him the gospel and leads him to forgiveness. Slug eventually learns to trust and obey and is born again as a butterfly.
This book teaches children to grasp and accept that God has a special purpose for every life, and true happiness is found in living His plan.
