A jellyfish insists on following SpongeBob home after a day out at Jellyfish Fields, so SpongeBob decides on keeping it as a pet at his home. Squidward warns SpongeBob that jellyfish are wild animals and that they should not be domesticated, but SpongeBob completely ignores him. At home, SpongeBob dances with the jellyfish to loud techno rave music, which annoys Squidward to no end. After 12 hours of this form of nonstop partying, SpongeBob finally decides that it is time to go to bed, but this Jellyfish does not want to stop. SpongeBob eventually forces it to go to bed by tying a leash around it and ties it to his bed. Gary tries to tell SpongeBob he should not be keeping a wild animal, but SpongeBob does not listen. During the night, while SpongeBob sleeps, the jellyfish escapes and brings lots of his friends into his house.
The next morning, SpongeBob wakes up to find his living room filled with hundreds of dancing jellyfish. He attempts to make them leave, but to no avail. Squidward, annoyed that the music has been going on for 18 hours and has not been able to get any sleep all night, angrily calls SpongeBob on his conch phone to tell him that he has had enough of the loud music. A jellyfish picks it up and sprays him with jelly over the phone. Irritated, Squidward decides that "two can play at this," and starts loudly playing his clarinet, angering the jellyfish with his terrible playing, who start destroying SpongeBob's house. SpongeBob asks Squidward to play his clarinet a little "better," as an insulted Squidward sarcastically responds this request. However, Squidward intentionally starts playing even worse and much louder with megaphones and a microphone. This prompts the jellyfish to angrily go to his house, as he cowardly tries to promise to stop playing, but they sting him before returning to SpongeBob's house. A sting-covered Squidward says to SpongeBob "Everybody's a critic. You won't be hearing from me anymore," and gives him his clarinet before leaving. The jellyfish hastily take it from SpongeBob, break it in half, burn it, and dance around it.
This further angers SpongeBob, who attempts to remove the stereo system, destroying it in the process, and the enraged jellyfish begin stinging and chasing him. SpongeBob and Gary go up to the roof of the house, but the swarm follows them outside and surrounds them. SpongeBob tells Gary that he was right. Then Gary drives them away by clicking his eyes together, producing a sound that calms the Jellyfish. SpongeBob tells Gary to keep doing this, and puts him on his head. SpongeBob walks downstairs and out the front door, with the Jellyfish following him. As he leads them back to Jellyfish Fields, more sounds join Gary's clicking, eventually becoming a full-fledged song. Taking advantage of how the Jellyfish are now distracted, SpongeBob quickly flees the area with Gary.
In the last scene, SpongeBob shakes with Gary as the French narrator declares: "Today, SpongeBob has learned one of the sea’s harshest lessons; wild animals can throw very wild parties." Then the severely stung Squidward is shown settling into his bathtub to recover from his stings.

- This episode is also available on SpongeBob SquarePants Volume 2 on GBA Video and on VideoNow.
- This is the first episode to use CG effects, specifically when SpongeBob's house jumps around and then pans over to Squidward's house. The second was in "Squeaky Boots".
- This episode was filmed on September 28, 1998.
- This is the second episode with jellyfish on the title card. The first is "Jellyfishing."
- Additionally, there are 18 jellyfish on the title card.
- Even though SpongeBob is able to sleep through the blasting music in his own house, Squidward is kept up all night by it.
- In the Polish dub, this episode is titled "Imprezka z meduzami," which translates to "A Party with Jellyfishes."
- In the Arabic dub, Squidward says 20 hours instead of 12, and 30 hours instead of 18, when commenting about how long SpongeBob has been partying with the jellyfish.
- According to the Complete 1st Season Disc 1 description of this episode, the jellyfish in this episode are all male.
- When SpongeBob leaves his room when he wakes up, a portrait of him and Patrick can be seen. In the aforementioned portrait, the former is purple and the latter is mint green, unlike their usual colors.
- It is likely that the portrait is a painting of SpongeBob and Patrick.
- This is the first episode to use the APM tracks "Chief Taravana" and "Furtive Footsteps."
- This is one of two season one episodes, along with "SB-129," with a small scene that tests digital ink-and-paint animation, as well as the first episode in the series to use it. In this case, the shot of SpongeBob standing on a hill in Jellyfish Fields with the jellyfish swimming was done digitally.
- This is the first time Squidward visits SpongeBob's pineapple.
- Squidward says he never visited SpongeBob in "Squid's Visit," hinting that episode takes place before this one.
- TeenNick premiered this episode on May 18, 2021.
- "Stadium Rave" is very similar to "Get Ready for This," a song commonly played at basketball games.
- Since 2012, the title card is always skipped whenever this episode is broadcast on Nick@Nite. This is because the Nick@Nite version uses an old non-remastered print from 1999. Just like "The Inmates of Summer," this could possibly be due to a mastering error that occurred when Nickelodeon started time compressing all of the full-screen episodes at the time to make room for commercial breaks. This mishap is also present for occasional "best of" Nickelodeon broadcasts whenever this episode is paired up with another non-remastered episode outside of season 1 and early season 2.
- The title card is left intact for all Nicktoons broadcasts and whenever Nickelodeon airs this episode with "Hall Monitor" because remastered prints are used.
- For the April 2, 2021 airing, this episode was paired up with "Jellyfishing." The title card was retained because Nickelodeon used remastered prints for both episodes.
- When Squidward says, "SpongeBob is the only guy I know who can have fun with a jellyfish...for twelve hours!," the night stand with the lamp moves from the left to the right. The pillow that was under the clarinet was absent the first shot, but appears in the second one.
- When Squidward plays the clarinet out of the window, he is wearing his pajamas. However, after SpongeBob pops his head out of the window and says "I don't think the jellyfish like it," Squidward is seen wearing his brown shirt. Then after Squidward sets the speakers, he is wearing pajamas again. When Squidward goes to SpongeBob's house, he has his brown shirt on again.
- This all happens in under a minute.
- SpongeBob's living room is on the first floor, but when he pops his head out the window, telling Squidward to play his clarinet better, he appears to be on the second floor.
- When SpongeBob grabs the stereo box, the stereo's speakers appear brown instead of black.
- Before SpongeBob says, "Gary, you were right. Thanks for not rubbing it in," Gary's mouth moves to say "Meow," but no words or sounds come out.
- Throughout the episode, the texture of both SpongeBob and Squidward's houses changes. An example of this is that once, they become a lighter shade of their normal color.
- When SpongeBob and the jellyfish are dancing, the fish with the hook in the background's eye kept moving.
- Both SpongeBob and Squidward are stung by the jellyfish, but Squidward has painful welts from said stings, while SpongeBob does not.
