The episode begins with Squidward waiting for the bus in front of his house. He's wearing a Hawaiian shirt, has a suitcase in hand, and has an exterminator's fumigation tent covering his house. SpongeBob comes over and thinks that the tent is a circus tent, but Squidward angrily tells him otherwise, saying that the tent is for getting rid of Sea Urchins that have infested his house. Patrick suddenly comes out of the tent, also thinking that his house is a circus, exclaiming that it was boring. Squidward storms off and boards the arriving bus, telling SpongeBob and Patrick that he'll be staying at a hotel for the next few days in order to have peace and quiet. In the next scene, Squidward arrives at the hotel, and meets the manager. After the manager cracks a couple jokes, much to Squidward's annoyance, Squidward gets his room key. Squidward is very delighted with his room, and decides to relax by taking a bath. While bathing, SpongeBob and Patrick are seen running through Squidward's room, and end up bumping into each other, excitedly exclaiming on how much they love playing "Hotel Slam N' Run". After they leave, Squidward comes out of the bathroom, knowing that he heard a noise, but soon brushes it off as him being "not relaxed enough".
Soon after, Squidward decides to order room service for his hotel room, but SpongeBob and Patrick (who have their voices disguised), are on the other end. After hanging up the phone, the hotel manager comes back and thanks SpongeBob and Patrick for filling in for him on the phone, giving the two a treat as a reward. SpongeBob and Patrick arrive to Squidward's room on a cart, and are happy to see their friend. Squidward is not so happy though, and demands an explanation as to why SpongeBob and Patrick are also in the hotel. They explain that the hotel is hosting this year's annual Jellyfishing Convention, and that Squidward's hotel room is in-between both of theirs. As SpongeBob and Patrick conga-line out of Squidward's room, Squidward boards up his room and yells for SpongeBob and Patrick to stay away from him and leave him alone. Later, Squidward tries to enjoy various activities in the hotel, such as the spa, gym, and pool areas, but is annoyed by SpongeBob and Patrick's presence. After Squidward leaves the pool area, he sees SpongeBob and Patrick in the hotel halls, and tries to escape them, only to see them at every single turn (with one exception, where he somehow sees Mrs. Puff when he turns around). Squidward backs up against a door and begs for SpongeBob and Patrick to leave him alone, but SpongeBob warns that the door behind him leads to the Jellyfishing Convention.
A couple of the attendees at the convention notice Squidward, and drag him inside, leaving SpongeBob and Patrick to follow. Everyone at the convention welcomes Squidward with open arms, but he hates it. Later, SpongeBob and Patrick notice Squidward hiding in the corner, and are happy that everyone seems to love him. Squidward is not happy though, saying that everyone loves him so much that they won't let him leave. A pair of fish confirm this, saying that they love Squidward, as both of them head into the restrooms while leaving their Jellyfish mascot costume behind. Squidward suddenly gets an idea; if he puts the costume on, he can leave the convention undetected. As he is doing so, an announcement is made at the convention, much to the excitement of the crowd; It's time for the annual Jellyfish mascot hunt! Squidward runs away in panic, and the crowd, including SpongeBob and Patrick, give chase through the halls of the hotel. Squidward soon notices there's a button inside the suit called "The Zapper" which allows him to electrocute anything with the costume's tentacles. Squidward gets a kick out of this, and starts running back towards the crowd, gleefully zapping people left and right. He soon approaches the manager at his desk and zaps him too. Squidward then grabs the nearby phone and calls pest control, frantically telling them that the hotel has a infestation of jellyfish...fanatics. Exterminators arrive and cover the entire hotel with a fumigation tent, and SpongeBob and Patrick question if Squidward made it out okay. We then cut to inside the hotel, where Squidward is seen in his room, happily dancing while wearing a gas mask, as the episode ends.

- This episode is available on the SpongeBob SquarePants Vol. 20 and is also available on The Complete Twelfth Season DVD.
- Before this episode premiered on March 7, 2020, Amazon accidentally released it on July 31, 2019, alongside with its sister episode "Biddy Sitting" until it was taken down by Nickelodeon a few days later.
- This is the second time in a row that an episode was released by Amazon until it got taken by Nickelodeon. The first is "Surf N' Turf."
- A clip was released on Nick TV a week before this episode aired on American television.
- This episode was paired up with "Shell Games" during the original American airing, but has since been re-airing with "Biddy Sitting."
- Coincidentally, they both have to do with an unexpected guest visiting at Squidward's house.
- There are 29 jellyfish in the title card.
- The title card is similar to those of "Jellyfishing," "Jellyfish Jam," and "The Pink Purloiner," as all four contain jellyfish.
- "SpongeBob Theme" plays as a title card track for the first time in 19 years since "Dying for Pie."
- When Squidward's bus arrives at Hotel Halibut, Jim's limousine from "The Original Fry Cook" can be seen outside the hotel.
- The blue suit SpongeBob wears for room service is the same suit he wears in "Krusty Towers."
- In the UK and Ireland, the scene with Squidward stinging everyone is altered so the background does not flash, possibly due to causing seizures to the viewers.
- This was the last episode to premiere before the COVID-19 pandemic began.
- In the Italian dub, this episode is called "Hotel da incubo," which translates to "Nightmare Hotel."
- The title is a pun on the Jolly Roger, which is used to identify a pirate ship that is about to attack.
- The scene where SpongeBob and Patrick appear at the end of the hallway is a possible allusion to The Shining.
- The Blue Plate Special is a reference to Kmart's trademark Blue Light Special.
- When SpongeBob, Patrick, and the other hotel guests form a conga line, SpongeBob's mouth disappears for a few frames.
- The zapper does not appear until Squidward needs it.
- Right at the beginning, when SpongeBob says "Oh boy, a circus!", the picture glitches for a frame. Said frame glitch makes the picture give the illusion that it's moving up.
