The Krabby Patty Secret Formula is one of the Foundation Elements in LEGO Dimensions 2: The Rise of Enoch, from the SpongeBob SquarePants franchise.
Background[]
The Krabby Patty secret formula is the recipe for the highly popular Krabby Patty burger sold by the famous Bikini Bottom restaurant, the Krusty Krab. There are many variations of the Krabby Patty, but all have one secret ingredient, which is yet to be identified or revealed. It first appears in the episode "Imitation Krabs."
Throughout the series, Plankton commonly tries to steal the formula in order to improve the popularity of the Chum Bucket, however, he fails every single time, except in The SpongeBob SquarePants Movie.
