This is the page about the city. For other uses, see Rock Bottom (disambiguation).

Rock Bottom is a small city in a deep-sea trench located beneath Bikini Bottom. It first appears in the episode of the same name and makes other appearances in the franchise afterwards, but the city does not make its second episode appearance until "Out of the Picture." It later makes a third appearance in "Food PBFFT! Truck." It is currently slated to make an appearance in the second season of The Patrick Star Show.[1]



The road between Bikini Bottom and Rock Bottom is so perfectly vertical that it can only be accessed or departed by a bus or balloon and also has a 90-degree angle when entering and exiting the city to go back into Bikini Bottom. Bikini Bottom cannot be seen from Rock Bottom due to the 90-degree angle on both sides and due to no sunlight reaching it. The entrance to the city is a 90-degree angle, as confirmed in the episode of the same name. Because of this, the only traffic on the road in the Rock Bottom part of the road only consists of buses.

SpongeBob blows raspberries in an attempt to speak the Rock Bottomite dialect.

Sunlight seemingly does not reach this part of the ocean, so everything is always pitch black except for a few street lights. Signs are written using Roman letters, as English, though often abnormally oriented. Many words are on Rock Bottom signs that are recognizably English are abnormally spelled. The soil is green with living sludge that can talk. Most residents of Rock Bottom are bioluminescent and generally very creepy looking. They speak a highly unusual dialect of English which uses raspberries. The intelligibility between it and the speech of Bikini Bottomites and other sea creatures is lopsided; Bikini Bottomites seem to find the Rock Bottomite dialect strange but understandable, while Rock Bottomites have a very hard time understanding Bikini Bottomites who do not attempt to use raspberries in their speech.

The entry area of Rock Bottom contains a "Kandy" Machine. The road leads back to Bikini Bottom and restrooms, although outsiders cannot tell which is the men's room and which is the women's due to the use of right side up and upside-down question marks to mark them, and are unable to determine the genders of the inhabitants.

Rock Bottom also has a major bus station, although the bus is extremely hard to catch. There is also an information booth with extremely long waiting lines. SpongeBob attempted to be first in line during his first visit, but the line was already full, so he was forced to take the 329th place in line.

There is also a police station and a prison, as seen in the video game SpongeBob's Boating Bash. There are many billboards throughout the town.

Video game appearances[]

Rock Bottom is featured in several SpongeBob SquarePants video games. The city's first appearance in a video game is Legend of the Lost Spatula.

In SuperSponge, it is the fourth chapter of the game.

In Employee of the Month, Rock Bottom is the location of the game's second chapter. It also includes a TV network, WSEA TV, with weatherman Gary Gulper, and a soda bar called the Rusty Anchor, run by a muscular fish named Big Mac. The weather wizard of Rocky Town, named Marlin, lives there.

In Battle for Bikini Bottom (Rehydrated), Rock Bottom is the sixth level in the game in order. The main mission of the level is to collect artwork stolen from the Rock Bottom museum and return them to Mrs. Puff. The player also travels to the Trench of Advanced Darkness, a trench that is lower than the city itself. There is also an episode reference to "Rock Bottom" in the game; if SpongeBob approaches the Kandy Machine, a small cut-scene will play and a bus will stop next to the machine before leaving.

In The Yellow Avenger, this is where the player finds the Flying Dutchman. They can also see the bus station, which is accessible. There is also a giant anchor, and a vending machine can be found inside the bus station.

It appears in SpongeBob's Truth or Square during the 24-hour shift flashback level. It is where the entire level occurs and takes place.

It appears in the game SpongeBob's Boating Bash as a driving area.

It appears in the mobile games SpongeBob Marbles & Slides and SpongeBob: Patty Pursuit as levels.

It appears in Plankton's Robotic Revenge as the second location.

A Halloween variant of this city is one of the main locations in the The Cosmic Shake.


  • The outlandishly creepy appearances of Rock Bottom's residents are based on the appearance of deep sea creatures in the real world, which are generally more "deformed-looking" than sea creatures in higher levels of the ocean.
  • It has an appearance similar to the monster-infested trench on the way to Shell City.
  • Rock Bottom makes its second in-series appearance in the season 10 episode "Out of the Picture," marking the city's first appearance in the show in 17 years.
  • Though not known to be used in any real-world language, raspberries, such as those in the Rock Bottomite dialect, can be classified as linguolabial trills. Their exact role in the Rock Bottomite dialect, however, is unclear. In addition, the stacking of letters on signs in Rock Bottom is similar to the stacking of letters in Hangul.
