Jellyfish Fields is a vast area in Bikini Bottom where all the jellyfish reside. It first appears in the episode "Tea at the Treedome."



Over 4 million jellyfish reside here, as evidenced in the episode "Jellyfish Hunter." In "Born to Be Wild," it is also revealed that Jellyfish Fields is 50 miles long. There are two entrances: one at the beginning and one at the end, so it stretches out to other towns.

Other creatures live here as well, such as clams, leeches, and poisonous sea urchins.[1] Formerly, the Jellien Leader lived here.[2]

It is best known as the place where SpongeBob and Patrick go jellyfishing, a sport in which one catches jellyfish with a net and lets them out once caught. According to the episode "The Pink Purloiner," every year, for three days, different kinds of jellyfish from all over the world come to Jellyfish Fields. This is known as "The Great Jellyfish Migration."


In "SpongeBob's Last Stand," Jellyfish Fields is destroyed by Plankton to create the Shelly Superhighway, but returns to normal when SpongeBob and the other Bikini Bottomites intervene.

In "Jellyfish Hunter," Jellyfish Fields is partially destroyed by SpongeBob as he hunts down every single jellyfish for Mr. Krabs' Jelly Patties except Friend so Jellyfish Fields, as it is known, was destroyed for a very short time.

In "Squirrel Jelly," Sandy burns Jellyfish Fields to flames as a result of skating rapidly throughout the place.

In "The String," SpongeBob destroys Jellyfish Fields along with all of Bikini Bottom while pulling the titular string.
