Smashed potatoes that look like Squidward are a food item that appear in the episode "There's a Sponge in My Soup."
They are white smashed potatoes served on a light blue Krusty Krab plate. Tiny chunks of potato skins are visible. They are clumped in a way that resembles Squidward's face. The smashed potatoes are very messy, as they leave globs all over the plate and Mr. Krabs' claw and arm.
In the rough storyboard by Kelly Armstrong, the potatoes were much more clumpy with a bigger "nose" on Squidward and no globs coming off of the plate.
Role in episode
Mr. Krabs uses the smashed potatoes as an ingredient for the Krabby Soup. The potatoes are still caked to a customer's plate when Mr. Krabs brings them out, so he has to use a knife to slide them into SpongeBob's soup pot. They cause the soup to bubble after being added.
