Zookeeper Fred loves snakes, but his favorite is a tiny green snake named Vern. Vern is sneaky and constantly tries to hide in Fred's lunch. When Vern gets loose in the zoo and lands atop a boy's head, it's trouble! A few citizens demand that all the snakes must go, and the Mayor closes the zoo until City Council decides what to do. Is Vern a menace? Are the snakes a danger to society, or are they a valuable resource for everyone? And who gets to decide? The Questioneers need all their talents to help Zookeeper Fred, but in the end, it's Aaron's art that leads the way.
