The Krusty Krab Pizza resembles any regular cheese pizza. It has eight slices and features pepperoni and mushrooms. It comes in a white cardboard box big enough to hold the pizza.
Role in series
Mr. Krabs sends SpongeBob and Squidward out to deliver the pizza. It takes them the entire episode to deliver it, and when they get there, their customer, Tom, requests for a Diet Dr. Kelp, although he apparently never ordered one in the first place, or Mr. Krabs never told SpongeBob and Squidward. After SpongeBob tells him this, the angry customer refuses to eat or pay for the pizza without his drink. He insults SpongeBob by asking him if he ever thought of the customer, to which SpongeBob breaks down crying. Squidward, however, in a rare change of heart, stands up for SpongeBob and slams the pizza in Tom's face, saying that "this one's on the house," although this could also be because he felt as if he made the delivery for nothing.
It also appears in "I ♥ Dancing," when it lands on Frankie Billy's table along with a drink, nachos, a sandwich, and a suit of knight armor.
The Krusty Krab Pizza is shown to have mushrooms and pepperoni even though the original Krabby Patty recipe is not known to have mushrooms and pepperoni, although the "pepperoni" may be sliced Krabby Patty meat.
