My teacher is a Monster! No I Am Not

A young boy named Bobby has the worst teacher. She's loud, she yells, and if you throw paper airplanes, she won't allow you to enjoy recess. She is a monster! Luckily, Bobby can go to his favorite spot in the park on weekends to play. Until one day... he finds his teacher there! Over the course of one day, Bobby learns that monsters are not always what they seem.
