Krabby Patty (The Life of SpongeBob SquarePants)

The Krabby Patty is the signature dish of the Krusty Krab. It is the most popular food in Bikini Bottom, and a driving force behind the popularity of the Krusty Krab, which itself has become the most popular restaurant in the city. The Krabby Patty is made out frozen hamburger with fresh lettuce, crisp onions and tomatoes with undersea cheese, pickles, mustard, ketchup, and with a special secret formula (which has never been revealed since the invention of the Krabby Patty). The Krabby Patty is sold for $2.99 (99¢ on Wednesday).

Krabby Patty Secret Formula
The Krabby Patty Secret Formula is arguably the best-known trade secret in the history of Bikini Bottom. The content of the recipe is known only to the restaurant's owner and operator, Eugene H. Krabs, who has refused to reveal it to anyone since the invention of the Krabby Patty - knowing that his archnemesis Sheldon J. Plankton is constantly trying to steal the formula and produce the Krabby Patty himself. It is known that a copy of the recipe exists (Plankton has made numerous unsuccessful attempts to steal it), but its exact whereabouts are unknown; rumors say that Krabs carries it around with him, or he keeps it in a vault somewhere in the restaurant or his home.
