Spongebob - Kelp Fries

Kelp Fries (sometimes known as Krusty Fries or Sea Fries) are a common side dish served at the Krusty Krab. Kelp fries have had different appearences over the years.

Kelp Fries made it's debut in the episode "Greasy Buffoons." Later in "Kracked Krabs," SpongeBob was seen making the fries (though using potatoes instead of kelp).

In the episode "Shellback Shenanigans," SpongeBob brought home a bag of kelp fries for Gary the Snail to eat when the Krusty Krab ran out of Krabby Patties, even though Gary doesn't like this food. In the episode "Whelk Attack," Mr. Krabs offers kelp fries to the giant whelks, but they swallowed Mr. Krabs instead making him shout, "I'm not on the MENU!"
