The Patty Pal toy looks similar to a Krabby Patty, except with pickles for eyes, ketchup for a smile and dimples, and small white bendy straws for arms and legs. It is also smaller than the regular Krabby Patty. It costs $13.00.
Patrick spends the rest of the day with the toy, but when the two return to their houses at night, he promises to let SpongeBob play with it the following day. As the next day approaches, however, SpongeBob and Patrick engage in a war over how long one another gets to have the toy, showing that Patrick broke his promise.
After it remains undecided who gets to keep Patty Pal, Patrick selfishly eats it as another resolution. However, luckily, a whole shipment of Patty Pals are delivered to the Krusty Krab, thus giving SpongeBob and Patrick their own toys, so that they no longer have to worry about sharing.
If Patty Pals were actually made out of real Krabby Patties, they would soon deteriorate and become spoiled. This did not happen to SpongeBob and Patrick, despite being played with all day and all night. Though, this is what happened to Patty in the episode "To Love a Patty."
