The episode begins with two kids named Timmy and Tina in a treehouse, attempting to get the hiccups. At first, Timmy takes out a can of Fizz Bomb soda, drinks it, and then burps, but that does not work. In the second attempt, they eat a bag of spicy kelp chips, which causes their mouths to burn and then hiccup. In the process, they let out hiccup bubbles. Two of their hiccup bubbles touching each other combines into one bigger bubble and Tina gets the jar to put the bubble in. They trap the hiccup bubble in a jar, and laugh about how this will make a great prank. They release the hiccup bubble into Bikini Bottom, which is about to land on an old woman, but she unknowingly blows it away while blowing her nose. The hiccup bubble then lands on SpongeBob while he is skipping down the street, causing him to get the hiccups.
Later, at the Krusty Krab, SpongeBob is about to prepare a fresh batch of Krabby Patties, but his hiccups interfere. At first, SpongeBob uses this to his advantage, using his hiccups to bounce the Krabby Patties off of his head, but this quickly spirals out of control. Mr. Krabs walks into the kitchen to see what is going on, to which he realizes SpongeBob has a case of the hiccups. He attempts to scare the hiccups out of him, but this proves unsuccessful. Mr. Krabs sends SpongeBob home for the day, but not before SpongeBob hiccups the bubble out of his mouth and onto Mr. Krabs, passing the hiccups onto him. Mr. Krabs walks back into the restaurant to greet Mrs. Puff, who is waiting in line, but Mr. Krabs' hiccups prove to be an annoyance. Mrs. Puff claims the hiccups are not contagious and kisses Mr. Krabs on the cheek, and Mr. Krabs unknowingly passes the hiccups onto her. Mrs. Puff then rushes into the restroom and tries drinking water upside down to get rid of the hiccups. Pearl then also walks into the restroom and is confused by what Mrs. Puff is doing. Mrs. Puff then accidentally spits water all over Pearl's pom-poms, making her upset. Mrs. Puff tries to apologize to Pearl, but ends up passing the hiccups to her, causing Pearl to storm out of the restaurant. Pearl attempts to practice cheerleading, but her hiccups get in the way. She ends up passing the hiccups to a group of jellyfish, and she happily finishes her cheer.
The Jellyfish then fly past the comic book store where Bubble Bass is reading a comic book, and pass the hiccups onto him. His hiccups cause him to sneeze on his comic book, making him upset. Old Man Jenkins then approaches Bubble Bass and mocks him, saying how back in his day, hiccups could turn someone inside out. This also happens to Bubble Bass, who panics and runs away. We then cut to Perch Perkins, who is reporting the Hiccup Plague on the news, but he just laughs it off until Bubble Bass (still inside out) grabs Perch Perkins' microphone, claiming the Hiccup Plague to be real. He then hiccups, causing the hiccup bubble to travel inside the microphone, and into telephone wires leading to the Chum Bucket, causing Karen to get the hiccups, who then passes the hiccups to Plankton. The hiccups cause Plankton to accidentally drop a couple of beakers he was using, which creates an explosion that sends him flying. He then lands on the ground right in front of Patrick, who ends up accidentally stepping on him. He then picks up Plankton, who ends up passing the hiccups onto him. Plankton laughs in his face and then runs away. Patrick then starts hiccupping, causing him to panic, and he bumps into Squidward. Patrick begs Squidward to help him get rid of the hiccups, but then passes the hiccups onto him. Squidward berates Patrick, saying that hiccups are not contagious, but when he starts hiccupping himself, he panics and takes off.
We then see Mrs. Puff, Pearl, and Bubble Bass, who are walking down the street together. Squidward then approaches them and starts uncontrollably hiccupping. This causes them to panic and flee. Squidward is then approached by SpongeBob, who states that he will willingly take the hiccups if Squidward hugs him. He begrudgingly does so, and passes the hiccups onto SpongeBob. Squidward then retreats gleefully, while SpongeBob says goodbye to Bikini Bottom, while Timmy and Tina (the two kids from earlier) are seen giggling behind a mailbox. SpongeBob is then seen sitting on a large piece of coral while sipping on a carton of grape juice. SpongeBob then hiccups, causing him to fall off the coral, and lands in Sandy's arms. SpongeBob is alarmed and tells Sandy to stay away from him as he still has the hiccups. Sandy states that she wants to attempt to cure SpongeBob of the hiccups and take him back to her treedome.
At Sandy's Treedome, SpongeBob is seen in a small tank, while Sandy, Mr. Krabs, Mrs. Puff, Pearl, Bubble Bass, Patrick, and Squidward look on. Mr. Krabs once again tries to scare the hiccups out of SpongeBob, but fails. Mrs. Puff suggests drinking water upside down, Pearl suggests to do a cheer, Bubble Bass suggests hiding pickles under his tongue, Patrick suggests eating Snail-Po, and Squidward suggests nothing. SpongeBob tries all of these options, but none of them end up working. Sandy tries to treat the situation "scientifically" and tickles SpongeBob, which actually ends up working. The hiccup bubble floats out of the Treedome as everyone cheers. The hiccup bubble then floats back to the treehouse where Tina and Timmy are laughing, but the hiccups are passed onto them. They both start hiccupping, causing their treehouse to jump up and down, as the episode ends.

- This episode is available on The Complete Twelfth Season and SpongeBob SquarePants Vol. 22 DVDs.
- This episode was released on The Complete Twelfth Season DVD on January 12, 2021, one year and three months before airing on American television.
- This episode was originally set to premiere on January 18, 2021 in the United States at 12:15 PM. However, there were concerns on this episode being unintentionally similar to the COVID-19 pandemic. As a result, the listing was changed and got replaced with the American premiere of "My Two Krabses." Amazon Prime Video failed to hear this update and ended up releasing this episode on January 19, 2021, one day after the planned American airdate. However, the episode was taken down from Amazon Prime Video by Nickelodeon a day later on January 20, 2021.
- This episode was also released on a few other streaming services through video on demand on its intended airdate.
- Despite being removed from the Nickelodeon USA schedule for January 18, 2021, clips from this episode were still shown in a promo for the Best Day Off Ever event.
- This episode got released on American iTunes on January 1, 2022.
- This episode was paired up with "Potato Puff" during the original American airing, but has since been re-airing with "Lighthouse Louie."
- In the French dub, the title for this episode is "Épidémie De Hoquet," which translates to "Hiccup Epidemic."
- The English title card was accidentally revealed on the official SpongeBob SquarePants Instagram and Facebook accounts.
- The final frame from this episode was revealed by mistake at the end of the premiere of "Lighthouse Louie" in the UK and Ireland airing.
- The treehouse shown in this episode looks similar to SpongeBob's clubhouse from "Club SpongeBob."
- Hiccups were previously a plot point of the comic strip titled "Hiccup And Away!," featured in the comic book Comic Crazy! and centered around SpongeBob getting the hiccups.
- Bubble Bass still has the pickles under his tongue like he did in "Pickles" and the SpongeBob Freestyle Funnies 2017 comic strip titled The Great Funnybook Giveaway!
- SpongeBob also tries Snail-Po again, which might be a reference to him trying it in "Missing Identity."
- This is the first episode for a few things:
- This episode, along with "Potato Puff," is the second instance in which the episodes premiered on Earth Day in the United States. The first was "SpongeBob's Last Stand" in 2010.
- This is the sixth episode to premiere in the United States a year or longer after its sister episode premiered. The first was "Gary Takes a Bath," the second was "Goo Goo Gas," the third was "Yeti Krabs," the fourth was "Pineapple RV," and the fifth was "My Two Krabses."
- There was no need for Mr. Krabs and Pearl to wear water helmets while in Sandy's treedome, as crabs and whales can breathe in or out of water. This continuity error also occurs in "Overbooked" and "Surf N' Turf."
- A clip from this episode was used in a video called "Funniest Moments from NEW SpongeBob Episodes! 😂" uploaded by the Nickelodeon Cartoon Universe official YouTube channel on March 19, 2021.
- Half of this episode was released on nickelodeon.la on March 24, 2021 and on nickelodeon.com.br on March 25, 2021.
