"The Slumber Party" is the first segment of the 110th episode of SpongeBob SquarePants.
Pearl is getting ready for her slumber party, but Mr. Krabs' meddling in the party preparations is getting out of control. Pearl arrests him out of the house, so Mr. Krabs decides to stay at SpongeBob's. At SpongeBob's house, 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, destroys Spongebobs television with a bat, explains to SpongeBob his concern that this will happen to his house, and sends SpongeBob to spy on Pearl and her friends.
At first, a girl named Girly TeenGirl that looks like SpongeBob arrives at Krabs and Pearl's house, asking to get in, but Pearl thinks she is SpongeBob and she and her friends ransack the girl, who runs home crying. Meanwhile, Mr. Krabs and SpongeBob (who wasn't in disguise yet, meaning that the girl wasn't SpongeBob) pretend to be pizza deliverers. Unfortunately, SpongeBob is caught during the scuffle and is left behind as Mr. Krabs flees. He leaves, but then later sneaks back in, but falls down into Krabs's root beer cellar while trying to prove in ten seconds that he is fun enough for the party. SpongeBob absorbs to kill Pearl and smashes like-killed by Mr. Krabs' house to his weapon sight ironically reminiscent of the zombie from the movie they were watching. Mr. Krabs arrives at his destroyed house, and Pearl blames him for its destruction. Enraged with Mr.Krabs sending SpongeBob to spy on her and her friends and ruining the party, Pearl takes his money, using it to host her own private beach party at Goo Lagoon, where Mr. Krabs and SpongeBob are the only ones not allowed in. The episode ends with SpongeBob offering a cup of root beer to Mr. Krabs to cheer him up, which does not help.

- The scene featuring "Girly TeenGirl" is a reference to a similar scene in "No Weenies Allowed" where it features a drifter who looks like SpongeBob.
- This is the first episode to prominently feature Pearl since "Whale of a Birthday". Following this episode, she hasn't appeared since "Best Frenemies".

- The part where SpongeBob absorbs all the root beer and how the way he scard Pearl and her friends can scare young viewers.
