SpongeBob SquarePants fan theories

SpongeBob SquarePants is an American animated television series created by marine biologist Stephen Hillenburg. Since the show's debut in 1999 on Nickelodeon, numerous fan theories, or assumptions about the show and its characters, have been made, with some being regarded as "weird".

Theories about the Krabby Patty secret formula
The Krabby Patty is a veggie burger sold by the Krusty Krab, a fictional restaurant in SpongeBob SquarePants. Numerous theories have spawned of what the Krabby Patty secret formula is made out of, ranging from completely nothing to cocaine. A notable theory about the Krabby Patty secret formula explains that Krabby Patties are made out of crab meat. Support for this theory comes from the season 3 episode "Mid-Life Crustacean", in which Mr. Krabs states, "So that's what I taste like.". In 2017, the series's creator Stephen Hillenburg confirmed that the Krabby Patty contained no animal products, thus debunking the crab meat theory. Another theory explains that the Krabby Patty secret formula is made out of "Poseidon Powder", which according to Urban Dictionary, is slang for cocaine.
