Role in series
Peas appear as Land Peas in this episode, where SpongeBob and Patrick mistake "pecan pie" for "peas-in-a-can pie."
According to Mr. Krabs, he used to cook peas when he was head chef on the S.S. Diarrhea, but Squidward thinks he used to cook peas on the S.S. Gourmet. However, Mr. Krabs actually cooks the peas on the stove while they are still in the can.
Peas are used to defend the Krusty Krab against Plankton. SpongeBob takes off his Krusty Krab employee hat so Mr. Krabs can pour a can of peas into one of SpongeBob's pores. Thereafter, he uses SpongeBob as a gun and makes the latter shoot the peas out of his holes and aim them at Plankton, which he does, but ends up failing as Plankton uses a bubble to protect himself.
"Goodbye, Krabby Patty?"
They appear in realistic form in the TV dinner tray depicted on the Lonely Krab box.
