Pearl is getting ready for her slumber party, but Mr. Krabs' meddling in the party preparations is getting out of control. Pearl kicks him out of the house, so Mr. Krabs decides to stay at SpongeBob's house. There, SpongeBob puts on a movie that shows girls having a slumber party and inviting their gangster boyfriends, who begin vandalizing the house. Mr. Krabs is horrified by this, and as a result, he destroys SpongeBob's television with a bat. He then explains to SpongeBob his concern that this will happen to his house and sends SpongeBob to spy on Pearl and her friends. Meanwhile, a teenage female sponge named Girly Teengirl from Farawayville who looks like SpongeBob arrives at Mr. Krabs and Pearl's house, asking to get in. However, Pearl thinks she is SpongeBob, and she and her friends attack the girl, who runs home crying. At the time, Mr. Krabs and SpongeBob pretend to be pizza deliverers while SpongeBob calls Girly Teengirl ugly.
Unfortunately, SpongeBob is caught during the scuffle and is left behind as Mr. Krabs flees. As a result, he had been turned into a pizza by the girls and sent back to Mr. Krabs, telling him that he failed the plan.SpongeBob later sneaks back in as a piano repairman, but Pearl and her friends already know his tricks and dropped a piano on him. He left and tried to tell Mr. Krabs to not spy on her again, but Mr. Krabs said that if he doesn't go to Pearl's party, then he is fired. Upset, SpongeBob goes back to Mr. Krabs' house and begs Pearl to stay at her party. Pearl is convinced, but he falls into Krabs' root beer cellar while trying to prove in ten seconds that he is fun enough for the party. SpongeBob absorbs all of Mr. Krabs' root beer to prove that he can be fun, while in hindsight ruining Mr. Krabs' house and putting Pearl and her friends in peril. Mr. Krabs arrives at his destroyed house, and he blames Pearl for its destruction and trusting her. Pearl is enraged with Mr. Krabs for blaming her and sending SpongeBob to spy on her and her friends and claims that Mr. Krabs is the only one at fault for ruining the party.
As punishment for ruining her party, Pearl steals all his money and uses it to host a private beach party at Goo Lagoon, where Mr. Krabs and SpongeBob are the only ones not allowed entry. The episode ends with SpongeBob offering a cup of root beer to Mr. Krabs to cheer him up, which does not help at all.
