The episode begins with Pearl being dropped off to her house by her boyfriend. She is excited while going home as she is excited to go to the party tonight, but when Mr. Krabs hears this, he says that since he is going to play cards with his friends, she is going to have Squidward babysit her, much to her dismay.
Squidward arrives to babysit Pearl as if he babysits her, he can have one shift per week without SpongeBob. Squidward tries to babysit Pearl, but she leaves while he is demonstrating what they could do. He goes upstairs to see what Pearl is doing, but gets scared when he sees that Pearl made a "R.I.P. Squidward" model while she was pretending to do arts and crafts.
After getting Squidward out of her hair, Pearl goes through a secret entrance in her room to hop in Dylan's boat to go to the party. Squidward goes back inside the room to check on Pearl but thinks that she ripped her neck after seeing that what looked like Pearl was actually her head made out of crafts. After seeing Pearl going away with Dylan after falling into the secret entrance, Squidward follows them with his recumbent bicycle.
Pearl enjoys the party with her friends until Squidward arrives and tries to get her back. Dylan tells her to forget Squidward and go breaching, so she decides to do that. However, she ends up getting stuck on the shore, and everyone at the party escapes. Squidward ends up saving her, and the two ride home. The episode ends with Squidward and Pearl deciding to prank Dylan by mailing SpongeBob to him, as the episode ends.
