A salad is a food consisting only the Krabby Patty's tomato and lettuce that was sold at the Kuddly Krab in the episode "Bossy Boots." Before it was sold there, Mr. Krabs opened a salad bar as a gimmick to get customers in the episode "Culture Shock."
Role in series
In "Bossy Boots," SpongeBob was supposed to make two salads. Pearl Krabs made one by removing everything from two Krabby Patties except the tomato and lettuce. SpongeBob SquarePants was shocked and apparently had never seen a salad before this day. Even though he was broken-hearted after destroying a couple of Krabby Patties, he sadly brought them to the customers (To the point of tears.). They appeared to be sad too.
In "Culture Shock," the Krusty Krab appeared to have a salad bar. In this particular episode, Mr. Krabs made the salad bar free after having a very long loss of customers. The salad bar is also seen in "My Pretty Seahorse" when Mystery eats out of it. Mystery also ate Mr. Krabs' money thinking it was salad.
Ironically a side salad is usually seen on the menu, indicating that SpongeBob does know how to make a salad.
This also means that customers do not order salads from the Krusty Krab.
SpongeBob calls the salads "Sa-lads" as a running gag in the episode "Bossy Boots."
In "Bossy Boots," SpongeBob doesn't know what a salad is.
