Plan Z-909 is just mentioned in the episode SpongeBob's Last Stand. The plan was made by Mr. Krabs. The plan is about Mr. Krabs (being forced to) selling the Krabby Patty Secret Formula to Plankton. This plan would be only used as a last resort which would be when the Krusty Krab would undoubtedly go out of business, then Plankton will take over it and the rest of Bikini Bottom.
Plan Z-909 was almost executed in SpongeBob's Last Stand. Before Mr. Krabs could sell the formula to Plankton, the Chum Bucket was attacked by jellyfish. This is the only recorded time Plan Z-909 had to be used.
