The episode begins with Mr. Krabs' stomach growling as the customers of the Krusty Krab start to get worried. He closes the restaurant and goes somewhere by going under a taxi, while SpongeBob follows him to give him a nickel he dropped.
It turns out Mr. Krabs has gone outside of Bikini Bottom to The Slop Pail, where he orders chum. SpongeBob sees that Mr. Krabs is eating chum and likes it, but he does not understand why. Mr. Krabs tells a story about how during one of his navy days, he barely made it back to his ship alive only to find it robbed of all their supplies (although in actuality, he had slept through the entire day while his crew ate everything) and was forced to eat chum due to being the only food left, and upon eating it, grew to love it.
SpongeBob promises to keep this a secret, and afterwards, the Slop Pail closes as the owner of the restaurant, Sal, wants to become a movie star. This leaves Mr. Krabs with no chum to eat that is not from the Chum Bucket. Back at the Krusty Krab, SpongeBob makes several types of chum with different ingredients as he is unable to make the actual chum recipe. However, Mr. Krabs says none of them are right.
Mr. Krabs tries to prevent himself from going to the Chum Bucket, but ends up searching for chum there anyway. Karen and Plankton come outside as they heard a noise, and eventually find out about Mr. Krabs' secret. Plankton gets a plan to offer a lifetime supply of chum to Mr. Krabs in exchange for the formula. Mr. Krabs' chum monkey goes for this offer immediately, and Mr. Krabs brings the formula, despite SpongeBob's warnings.
When Plankton takes the formula, he uses the Chum Bucket glove to prevent Mr. Krabs from taking his chum. However, he gets out and attacks Plankton, causing the formula to sink into the chum. Plankton decides to swim inside the chum to obtain the formula. SpongeBob tells Mr. Krabs that he should eat all the chum so he can reach the formula first, and he does so. He gets the formula, but gets extremely overweight and accidentally eats Plankton. To pass the time, Mr. Krabs, SpongeBob, and Karen watch Sal's latest movie in theaters, as the episode ends.

- This episode is available on the SpongeBob SquarePants Vol. 20 and The Complete Twelfth Season DVDs.
- This episode was paired up with "Plankton's Old Chum" during the episode's original American airing, but has since been re-airing with "A Cabin in the Kelp."
- This marks as the 500th episode segment of the series in production order.
- This is the first time the track "Aloha" has played since "Good Neighbors."
- It took 14 years for the track to return.
- This was the last 11-minute episode to premiere in 2019 and the 2010s decade, as well as the last episode to have a 2019 copyright date.
- This was Steve Fonti's first time working on an episode since "I Was a Teenage Gary" in 1999.
- This is the second episode Gilbert Gottfried guest-stars in, with the first being "SpongeBob's Big Birthday Blowout" when he said "Happy Birthday!" to SpongeBob.
- This is the last episode directed by Adam Paloian before he left the series to work on the Netflix original animated series The Cuphead Show!
- This episode's French title is "L'obsession," which translates to "Obsession."
- Shell City is mentioned by Sal when he says that he moved there to become a movie star. However, in The SpongeBob SquarePants Movie, Shell City is a gift shop on a surface and not an average underwater city, so Sal would most likely be killed there.
- However, since the end of the episode shows Sal successfully becoming a movie star, it is possible that Shell City mentioned by Sal is different from the one in the movie.
- It is revealed that Mr. Krabs likes to eat chum secretly.
- SpongeBob tells Mr. Krabs he cannot make chum the regular way. In reality, chum is a lure made up of fish parts, which explains why he cannot make that type of chum.
- When Mr. Krabs is digging in the trash, he throws out the robot game show host's head, a birthday cake, and a piano.

- The face Mr. Krabs makes after he says that SpongeBob's chum is dry resembles his Great Grandpa Krabs.
- The shoe that Mr. Krabs dug out of the trash resembles the one Gary wore in "Your Shoe's Untied."
- The credits for this episode are exactly the same as the credits for "The Grill is Gone," except that Vincent Waller and Marc Ceccarelli were credited as co-executive producers instead of supervising producers.
- Dr. Kelpington is a reference to Ernst Stavro Blofeld, a James Bond villain.
- Dr. Kelpington strapping down Fred and vaporizing him with a laser references the James Bond film Goldfinger.
- When Plankton, Mr. Krabs, and SpongeBob scream while the secret formula is falling into the chum, Mr. Krabs' pupils are offset from his eyes for a frame.
- In the French dub, all the credits were incorrect, with the credits being taken from "Hiccup Plague."
- In the Russian dub, all narrator's and Plankton's lines got removed for an unknown reason. This mistake got fixed when the episode re-ran on Nick HD on March 25, 2020.
