Wahoo Cray lives in a zoo. His father is an animal wrangler, so he's grown up with all manner of gators, snakes, parrots, rats, monkeys, snappers, and more in his backyard. The critters he can handle.  His father is the unpredictable one.

Mrs. Bunny Starch, the most feared biology teacher ever, was last seen during a field trip to Black Vine Swamp. The school’s headmaster and the police seem to have accepted the sketchy, unsigned note explaining that her absence is due to a “family emergency.” There’s no real evidence of foul play. But still, Nick and Marta don’t buy it. Something weird is definitely going on.
