The episode starts at the Krusty Krab when SpongeBob realizes they are out of tartar sauce, but when he checks the vat, he realizes it is empty and it has been there for 50 years. When Mr. Krabs yells at him to get back to work, SpongeBob explains the situation. Mr. Krabs gets an idea to start a time capsule.
The next scene shows the tartar sauce vat next to a hole with a large stage next to it. A huge line of people are in line to make contributions to the time capsule by handing things in, and Mr. Krabs tells SpongeBob and Squidward to handle them while he sells souvenirs. It shows several people making contributions, which Squidward critiques, but SpongeBob finds everything amazing. Mr. Krabs sells cheap souvenirs for outrageous prices. Patrick comes to make a donation of his favorite rock. Believing that this item is too ridiculous for a time capsule, Squidward tries to seize the break from Patrick. The struggle makes the rock fly in the air and it puts the wood behind him, flinging Squidward, SpongeBob, and Patrick into the time capsule, trapping them in and burying them alive. Mr. Krabs puts a copy of the Krabby Patty secret formula in the capsule, making Plankton interested.
In the time capsule, the three of them imagine what the future would be like until Squidward gets knocked out. Patrick then finds shaving cream which he mistakes for whipped cream, so he tastes it and finds it awful. Plankton drills into the capsule, hitting the shaving cream that sprays Patrick, which gives him a beard and Patrick sprays SpongeBob and Squidward. Squidward wakes up, thinking it has been 50 years due to the beard, and escapes through the hole Plankton created. The "future" is not what Squidward wanted, so he goes back to the time capsule, unknowingly stepping on the formula bottle on his way back, shoving it inside Plankton.
The episode ends with Plankton at the Chum Bucket constipated with his body shaped like a bottle and him sitting on a toilet, trying to get it out. Karen calls him "poopsy" and Plankton asks for more prunes.

- When this episode premiered, it was paired with "Shellback Shenanigans," but since it has re-airing with "Enchanted Tiki Dreams."
- The time capsule date has the year of 1960 on it and this episode aired in 2010. At the beginning, when SpongeBob sees the date on the time capsule as May 1960, he infers that it has been there for 50 years. This is true in real life, as 2010 is 50 years after 1960.
- Within all the chrome in SpongeBob's future thoughts, it is similar to "SB-129," although it takes 2,000 years after the main event, but "SpongeHenge" contradicts "SB-129" as well, as 3,000 years after the main event, there is no chrome background.
- In Indonesia, when Squidward says, "There's no way I'm letting you put your dumb rock in the time capsule." and "We just got buried alive, you idiots!," the words "dumb" and "idiots" are muted because the words "dumb," "idiot," "moron," and "stupid" are considered profanity in Indonesia.
- To date, this is the last episode to play the APM track "Chief Taravana."
- Pretzel Pals is a parody of Twister.
- The switch on the toaster that was donated was pushed down and did not have a cord.
- During the scene when Squidward looks at the plate, there is a noticeable cut when he sucks the plate into his nose. This can be seen when Squidward looks at the plate and sniffs it, and the camera cuts to the plate in his head.
- Throughout the scenes where fish are putting things in the capsule, the red ribbon which runs from the stand to the Krusty Krab repeatedly disappears and reappears.
- In the crowd outside the time capsule, there are duplicated fish.
- In Plankton's vision of a popular restaurant, Harold Bill Reginald Scott can be seen drinking with the straw overlapping his mouth.
- Mr. Krabs should have gotten SpongeBob, Patrick, and Squidward out of the time capsule when he put his copy of the Krabby Patty formula inside as he did see them.
- When Mr. Krabs throws the formula in the capsule, the capsule was full to the brim, but when the scene cuts back to SpongeBob and company, it was barely full and seemed to be a lot wider.
- When SpongeBob throws the plate, it breaks, but when they are trapped inside, the plate is back together again.
- When everyone is putting things into the capsule, it is next to a sign, but when Squidward is getting out of the capsule, it is next to the road.
- Perch Perkins is listed in the credits for this episode. However, Perch is not seen or heard in this episode.
- When SpongeBob and Patrick are playing Pretzel Pals, Patrick says, "Forehead on yellow" when he was actually using the back of his head.
