"Stay Cool" is the 51st episode of Season 2 of Kick Buttowski: Suburban Daredevil.
Kick and Brianna break Dad’s air conditioner on the hottest day of the year, but Brad is blamed and grounded for the whole summer. Kick and Brianna agree to keep their blunder a secret as Kick has a whole summer of stunts planned and Brianna plans to go to Camp Sometimes for the summer, but Kick struggles with the mounting guilt.
In the end, Kick confesses that it was he who broke it, much to Harold, Brianna and Brad's shock. Harold apologizes to Brad and Kick is punished by having to pedal a bike to power a fan in order to keep Harold and Brad cool (but the punishment is for lying as opposed to actually breaking the air conditioner; the air conditioner breaks because it's simply the cheapest model known to man, and is Harold to blame).
As Kick endures his punishment, Brianna throws the last of her stuff on top of the camp car, and leaves for Camp Sometimes. Kick says nothing ever happens to Brianna, but a banana peel on the road (the same one that Brianna throws out of her window earlier in the episode) makes the car slip, which results in her stuff falling off and ending up in the jaws of the alligator from "A Cousin Kyle Christmas". The camper car obliviously continues on its journey as the episode ends.
