This takes place Season 1 EP. 9

Chris says Harold, Geoff, and Bridgette are the hunters for the Killer Bass, and would be using blue paint balls for hunting and Owen, Beth, Lashawna, Kaleb, and Lindsay are the hunters for the Screaming Gophers and would be using orange paintballs for hunting. Everyone else are dressed as "deer" with paper antlers that the hunters are shooting with paintballs for "hunting". Kaleb went off by himself to find a person as a deer to shoot with his paintball gun and that's where he found Cody by himself. Cody was dressed as a deer with the paper antlers.

(P.S. you have a crush on him & this is a BL story)
