The Krabby Patty Secrer Formula is one of the main ingredients of the Krabby Patty. Every variation of the Krabby Patty always contains the formula and Sheldon J. Plankton is always attempting to steal the formula to help his failing restaurant, the Chum Bucket.
Role in series
A running gag throughout the series is Plankton's many attempts to obtain the Krabby Patty secret formula as a means to attract customers to his restaurant, the Chum Bucket, usually through disguise and deceit. All of said attempts have failed, usually ending with Mr. Krabs throwing him back to the Chum Bucket or snatching the bottle out of his hands.
