The Mobile Krusty Krab was a traveling restaurant and subsidiary of the Krusty Krab. It appeared in the episode "20,000 Patties Under the Sea."



It was a submarine slightly larger than a boat. Light red paint, or perhaps rust, covered the exterior.


Only one room existed in the submarine, the control room. There was enough room for a grill, the controls, and a serving window.


This establishment consisted of two employees:

  • Patrick Star - He works as a cook.
  • SpongeBob SquarePants - He drives the mobile restaurant despite not having a license and not being able to drive well.

Role in Series

Before the episode occurred, this somewhat primitive submarine was used by an unknown animal, most likely a human. Somehow, it sunk and became useless to control.

Later, SpongeBob and Patrick found its periscope sticking out of the ground, dug it, and took possession of it. At the Krusty Krab, Mr. Krabs had the idea of "bringing the Krusty Krab to the customers." He did so by converting the submarine into a mobile restaurant. While SpongeBob and Patrick were trying to sell Krabby Patties, Plankton attempted to use his own traveling restaurant. The duo had some unusual ways of selling the Krabby Patties; they paid the customers to eat and made a deal to get the customers to eat burnt patties (rocks). They accidentally fell into an abyss, but they unexpectedly sold Krabby Patties and chum-wiches from Plankton's restaurant to a monster. The monster went chasing Plankton as he thought Plankton was dessert. SpongeBob attempted to get out of the abyss, but left behind the heavy money, much to Mr. Krabs' surprise and horror. They managed to bring back several tons of colored rocks, however.

  • SpongeBob and Patrick's roles are somewhat reversed in this episode since SpongeBob's a good cook even though he's driving; and Patrick's a good driver even though he's cooking.
  • Patrick was never shown cooking Krabby Patties anywhere else in the series except in "Big Pink Loser" and "Bummer Vacation."
  • SpongeBob is able to drive this submarine with discipline, yet he doesn't obey traffic lights and still crashes occasionally.
  • SpongeBob referred to this machine as a UFO.
  • The steering wheel resembles a helm on a pirate ship.
  • It can be said that Patrick knows the secret recipe to the Krabby Patty, considering he is capable of making one correctly.
  • Unlike other vehicles in Bikini Bottom, the Mobile Krusty Krab doesn't have any wheels, however, it is propelled.
