Jellyfish Hunter

"Jellyfish Hunter" is a SpongeBob SquarePants episode from Season 2. In this episode, Mr. Krabs sends SpongeBob to collect jellyfish jelly so he can sell it as a condiment at the Krusty Krab.

Plot
SpongeBob is out jellyfishing in Jellyfish Fields. He catches a jellyfish, gently tickles out some of its jelly, and lets it go, naming it "Twelvy" on its way. He then spies a very rare blue jellyfish, the only jellyfish in the field he has never been able to catch and name, thus calling him "No Name." SpongeBob's attempt to catch this specimen ends in failure once again, despite having used himself like a rocket to get closer to it.

Later, SpongeBob goes on his five-minute lunch break at the Krusty Krab and puts the fresh jellyfish jelly on a Krabby Patty. A customer notices it and asks him what it is. After SpongeBob explains that it is "a Krabby Patty with jellyfish jelly," the customer is eager to try it himself, so SpongeBob provides him with a dollop. Amazed with its taste, the customer sings a song proclaiming its greatness and plops jelly on the patties of all the other customers, who enjoy it as well. Mr. Krabs comes out from his office to see what the fuss is about, and SpongeBob explains how he was sharing his jelly with the customers. Mr. Krabs at first considers tampering with the Krabby Patty recipe to be mutiny, but when the customer tells him that he will come back for lunch there every day for the rest of his life, Mr. Krabs officially puts the new Jelly Patty on the menu.

SpongeBob is tasked to go out and gather as many jellyfish as he can. He is delighted to be paid for jellyfishing, but Mr. Krabs tells him that it is part of his free time. SpongeBob stills agrees, though he asks Mr. Krabs to keep the jellyfish comfortable while milking them for jelly. Mr. Krabs secretly states to himself that he will keep them comfortable "in his wallet," hinting that he does not care for their safety. SpongeBob catches several jellyfish, with Mr. Krabs demanding more every time until Jellyfish Fields is completely deserted. SpongeBob concludes that there are no more jellyfish to catch, and begins to walk home.

As SpongeBob walks home, he feels that he is being followed. He turns around, mentioning that he feels like someone is trying to sell him something. The thing following him is revealed to be No Name, but he hides every time SpongeBob looks back. SpongeBob states that he is not interested in anything his hypothetical salesman is selling and rushes home. Upon arriving home, he closes the blinds of his windows in panic but soon laughs off the incident. SpongeBob then gets a strange call from No Name that only features him breathing before the call abruptly ends, with the line seemingly having been cut. Nervous, SpongeBob laughs it off as a wrong number call, but the lights go off shortly after and he laughs that off as well by stating that Gary must have forgotten to pay the electric bill. SpongeBob later sees a shadow that he believes is Gary crawling into the house and later into the kitchen, which SpongeBob thinks is a good idea as Gary would probably find food there. Shortly after, he enters the dark kitchen and sees a Jelly Patty where the moonlight is shining in from the window. He eats it at first but shortly realizes that something is extremely wrong when he finds that the patty contains blue jelly.

No Name shows up and SpongeBob ends up captured in a jar himself by the blue jellyfish. It then takes SpongeBob to a secret factory farm, where he discovers that Mr. Krabs is forcefully wringing every jellyfish dry to increase his bottom line, draining, harming, and possibly killing them. Realizing Mr. Krabs' unscrupulous plan, SpongeBob angrily confronts him. Mr. Krabs claims that they are having a tea party which initially distracts SpongeBob, but No Name informs him of the trick and SpongeBob declares his intention to free the jellyfish. Mr. Krabs is shocked when SpongeBob suddenly picks up a pipe wrench, but he uses it to fix the squeaky bolts on the door, much to his relief. SpongeBob tries to set the jellyfish free but is unable to open the door to their cage.

Mr. Krabs laughs and boasts of his sturdy voice-activated door that only opens when he says "Open," which consequently opens the door. The freed jellyfish swarm over Mr. Krabs, who tries in vain to ride off on the bike used to power the machine before realizing it is only an exercise bike. The jellyfish then give him a mighty zap before flying off. Thoroughly charred, Mr. Krabs meekly decides to take the jelly off the menu.

SpongeBob vows to never again let his net be used for anything except pure sports, stating that jellyfish are not meant to be kept in captivity forever. No Name gently enters his net, allowing itself to be caught. Touched, SpongeBob decides to name the jellyfish "Friend," and they share a handshake that ends up stinging SpongeBob, who laughs it off nervously as his hand proceeds to swell.
