Paper Patties look like regular Krabby Patties, but they are flat. They each have a patty, lettuce, and cheese. It is topped with a sesame seed bun, same as a regular Krabby Patty. The only way to make Paper Patties is to type in the order "1 Krabby Patty" into a computer connected to a printer with colored ink, and then a Paper Patty will come out.
Role in episode
These are created when SpongeBob is yelled at by Squidward for being "strange." After watching a video on how to be normal, SpongeBob makes some physical and mental changes (he loses his curves on the edges and his holes). He also brings a cubicle and printer at the Krusty Krab, which produces the Paper Patties.
It takes the customers a while to realize that the patties are made out of paper, but when they do notice it, they leave the Krusty Krab.
