Lima beans are an edible legume that appear in the episode "Krabby Land."
The beans are contained in a silver can; the label of said can is colored red with a white square on it. Inside the square, the food's name is written in black text. The words are stacked and there is an illustration of three lima beans between the two words.
Role in episode
Mr. Krabs puts together a cheap playground named Krabby Land. He also gets SpongeBob to go through torturous tasks to entertain the kids, including being force-fed lima beans. Krabs passes out coloring books and says that the kids who turn them in get to meet Krabby the Clown.
Krabby turns out to be Mr. Krabs in a colorful tie and a blue-painted tomato on his nose. The tough guy punishes Mr. Krabs by tying him up to two pieces of wood and force-feeding him the lima beans, with a tough gray fish helping him out.
Lima beans are mentioned in "Fools in April" when SpongeBob asks Squidward "Even the part about the lima beans and the car chase?"
