"Harvey is two years old. He has green eyes, red hair, and lots of freckles. Harvey likes to laugh, run, and play. Harvey can be stubborn when he wants his way. Mommy and Daddy say that sometimes Harvey is a monster." Monster Tails is the beginning of a series that focuses on the poor choices that toddlers tend to make in the "terrible twos" years when temper tantrums abound. Harvey is a typical 2-year-old who handles a simple need much differently than that of his older family members. As Harvey's behavior escalates, he transforms from a stubborn little boy into a ferocious little monster. At the end of the book, Harvey must make the right choice in order to solve his problem. Consequently, the reader gets to enjoy seeing him transform back into his toddler boy self after his behavior improves. This book invites not only comedy but may also be used as an educational tool for young children in how to handle their daily struggles. Parents and children alike should enjoy watching Harvey take form as he learns from his choices and how his behavior can be applied to real everyday life.
