Overview
Kyle is a police officer and Maddy's ex-boyfriend. He first runs into Maddy at a party at the water park that she co-owns with her stepfather, Chet. After a swarm of piranhas attack Maddy and Shelby, Kyle, Maddy and Barry report the situation to Mr. Goodman, who explains to them that the piranhas are entering the park via underground water pipes. It is later revealed that Kyle is actually working for Chet and is ordered to keep Maddy quiet about Chet's plans.
