Role in episode
They first appear at the beginning of the episode, where they are inside the Krusty Krab. Once there, one of the fish proceeds to tell SpongeBob and Mr. Krabs that they are looking for something "different" and "new." This causes Mr. Krabs to think of a new secret menu, then asking Sandy to create the Secret Patty.
After the hipsters are revived from their previous zombie state caused by the patties, they tell how much more they prefer the "vintage" Krabby Patties and that they "rule."
