Spongebob Squarepant - Pretty Patties

The Pretty Patty was originally an idea from SpongeBob as an attempt to attract new customers to the Krusty Krab in the episode "Patty Hype." They were much like ordinary Krabby Patties, except that they came in many different colors such as blue, red, green, orange, yellow, purple, plaid, and even glow-in-the dark. At first, SpongeBob was ridiculed for this idea, and he had temporarily left the Krusty Krab to pursue Pretty Patties as a personal business interest. As a result, Pretty Patties were never sold at the Krusty Krab restaurant. Regardless, SpongeBob instantly became successful after everyone in Bikini Bottom found out how great they tasted. This persuaded Mr. Krabs to eventually take over SpongeBob's business so he could get all the money. Unfortunately, the next day, it was shown that the pretty patties had strange effects on whoever ate them. This led to Mr. Krabs being run off by colorful people, and the business was shut down. Ever since then, Pretty Patties were never sold again or seen again meaning their first appearance is currently their last appearance and is their only appearance.
