Charm and Dirty Bird are two characters from the Zoom Boom book series. Their names are quite the opposite of their character. Charm is very messy; whereas, Dirty Bird is very tidy. However, although they are different, they are still good friends. Be Tidy, or Not?, is a book that allows the readers to understand and appreciate the differences in their friends. It teaches children not to judge the differences, but to accept people as they are, allowing them to be tidy, or not.

At a young age, Big Man's parents had taught him about Jesus and told him to tell his friends about their adventures. Every day at Golden Gate Training school someone meets the true Savior for the first time. By the time Big Man finishes his stories, everyone's eyes are always wide open, and their ice-cream cones are always melted. They end up wanting to know more about the "Savior," the hero in Big Man's stories who always comes to rescue him and his family from the enemy.
