SpongeBob goes on his early litter patrol when he catches The Strangler. After he calls the police, The Strangler (disguised with a fake mustache) decides to be SpongeBob's bodyguard. After three parties at SpongeBob's house, The Strangler tries to strangle SpongeBob, but never gets the chance to be alone.
SpongeBob and Patrick buy a prank called Invisible Spray. After taunting each other with the spray, they run out and decide to haunt Bikini Bottom while being invisible, preferably being ghosts. But with their last victim Mr. Krab, he washes them out with water and exposes them nude to the whole Krusty Krab, embarrassing them.
