It looks like and has the same ingredients as a regular Krabby Patty, only with the addition of toenail clippings and nose hair.
Role in episode
Squidward wants Mr. Krabs to eat it, but he refuses. SpongeBob then tells Mr. Krabs that is not a Krabby Patty with cheese, toenail clippings, and nose hair, so Mr. Krabs eats it. Unfortunately, there are toenail clippings and nose hair on the patty, as Mr. Krabs gets angry at SpongeBob. SpongeBob then tells Mr. Krabs that they were all out of cheese due to all of it being covered in Patrick's room, meaning it was a Krabby Patty without cheese, toenail clippings, and nose hair.
