Spongebob Squarepants - Jelly Patty

The Jelly Patty was invented by SpongeBob and consisted of an ordinary Krabby Patty topped with Jellyfish Jelly in the episode "Jellyfish Hunter." (He calls it "a Krabby Patty with Jellyfish Jelly".) The jelly made the Krabby Patty taste amazingly good, and proved highly addictive to those who consumed it. SpongeBob let Fred try a Jelly Patty and was so entranced by the taste that he served Jelly Patties to the whole restaurant, who were all amazed at the taste. Mr. Krabs saw how good the jelly was and tricked SpongeBob into catching all of the jellyfish in Jellyfish Fields so that he could profit off of their delicious jelly. SpongeBob did so and soon captured every jellyfish in Jellyfish Fields.

Blue Jelly Patty

After all of the jellyfish were captured, Mr. Krabs imprisoned them in a factory where he proceeded to drain them all of their jelly, sucking many of them dry. However, SpongeBob caught on to this with the help of the blue jellyfish, No Name, and freed the jellyfish, who zapped Mr. Krabs before returning home. Having been badly injured and having lost all of the jellyfish, Mr. Krabs took jelly off of the menu. As a result, Jelly Patties have not been sold or even seen at the Krusty Krab since.
