Rumor has it, the secret recipe contains Neptune's Powder (also known as cocaine). But like the rumors, it is hoax. The Secret Recipe doesn't exist, when Plankton tried stealing the Recipe, creating a fake music band. When Plankton gets a Recipe
bottle, the
bass breaks it making the Recipe readable, but it only shows gibberish. So yeah, it's just a marketing catch. Krabby Patty is just an ordinary burger. But with vegetarian
meat. (Stephen Hillenburg said. (
