He then decides to teach them a lesson. Just when he thinks his plan worked, Four Tooth finds himself in danger! Will his friends help him or is this the end of Four Tooth? Inspired by the Chinese idiom, 狐假虎威(hu jia hu wei) which is often used to describe people who bully others by boasting of their powerful connections, The Hyena and the Monster gives interesting twist to this idiom, and teaches young readers essential lessons about friendship.
