Jellyfish Jelly is simply jelly produced by Jellyfish. SpongeBob will occasionally collect some, but only a full jar. SpongeBob gave Fred a sample, and it was so good that he broke into a song and he gave a sample to everyone else leading to the success of the Jelly Patty until Mr. Krabs went too far and SpongeBob and No Name stopped him.
Jellyfish Jelly tastes very good, and proved successful. Some have different flavors, depending on the jellyfish. Whether it's the classic pink jelly, or No Name's jelly, you know what I mean.
 How to get
According to SpongeBob, you must disguise and catch the jellyfish quick then "milk" the Jellyfish's "udders" which jelly will come out.
