Pranks a Lot: SpongeBob and Patrick invest in some magic “invisible spray” at the local prank shop. They strip down and spray themselves – the stuff really works! They go on a major pranking spree, hitting just about everyone in town and getting away with it. It’s finally Mr. Krabs that figures them out and he puts a floodlight on them for the whole town to see. Suddenly the joke is on Patrick and SpongeBob-they have no clothes on!
