At the Krusty Krab, Pearl runs in crying so profusely that her tears begin literally flooding the restaurant. Mr. Krabs asks her what's wrong, and she explains that her prom date has just dumped her, and the prom is tomorrow night. Mr. Krabs suggests taking himself, but she starts crying, causing an earthquake. He then suggest he takes Squidward or one of the restaurant's customers to the prom, but she continues crying, which causes the earthquake to become worse. Ultimately, he chooses that SpongeBob should be the one that has to go with her. Pearl doesn't want to be embarrassed by SpongeBob, and begs him to do his best not to. At home, using a magazine as a guide, SpongeBob dresses up and uses extremely long artificial legs to make himself look "long, tan, and handsome" for Pearl. On the night of the prom, things initially work well for SpongeBob and Pearl. However, SpongeBob's costume soon begins malfunctioning, resulting in disaster and severely embarrassing Pearl. SpongeBob, after having broken everything at the prom, runs into the ladies' restroom crying. Pearl, feeling sorry for him, attempts to console him and restore his confidence.
This ultimately succeeds, and Pearl and SpongeBob join the prom dance. They begin doing a dance called "The Sponge", which everyone else soon begins doing. However, this results in many injuries and mass destruction. An angry mob forms and lifts up Pearl and SpongeBob, who think this means that they are popular until the mob throws them out of the building. SpongeBob apologizes, and Pearl says even though it was a disaster, it was really fun. Pearl says goodnight to SpongeBob as she returns home, and tries to get SpongeBob's attention, but as she does so SpongeBob appears to be frozen. Mr. Krabs congratulates SpongeBob on his success at the prom, and the real SpongeBob appears to retrieve his wax dummy of himself (which was seen earlier in the episode), and carries it off, laughing.
