After SpongeBob, Patrick, and Sandy are banned from playing pirate outside, they decide to turn their cabin into a pirate ship. SpongeBob pretends to be a jellyfish for research purposes.
Counselor Squidward is determined for his cabin to win the annual camp art competition. The Kamp Koral campers befriend a cute cow with a big appetite.
It's the annual foam-fisted all-camp karate battle, and SpongeBob trains to beat the butt-kicking Sandy. It's the hottest day of summer, but there's only one AC in the whole camp.
