Not to be confused with the Krusty Krab pizza.
The Pizza Patty is a Krabby Patty variation made by SpongeBob in the episode "SpongeBob You're Fired."
It is a burger that contains a whole pizza in between two sesame seed buns.
Role in episode
SpongeBob makes this burger when he applies for a job as a fry cook at Pizza Piehole. The restaurant's manager, Pizza Pete, does not like it and fires SpongeBob.
Later in the episode, Pete is among the restaurant owners fighting for SpongeBob because apparently, Pizza Piehole's customers like his Pizza Patties.
