Jelliens were evil jellyfish-like extraterrestrials.
Biology[]
Jelliens resemble green versions of normal jellyfish, only with visible brains (which real jellyfish lack), eyestalks and sharp teeth. They are able to create clones of creatures they eat. Unlike real jellyfish, they can't sting. Mayonnaise is lethal to Jelliens, which makes them melt into green goo upon contact.
History[]
After an anthropomorphic sea sponge named SpongeBob passes by a creepy cave, the Evil Alien Jellyfish Overlord eats a jellyfish and then makes a bunch more Jelliens. One of the Jelliens encases SpongeBob's starfish friend, Patrick and makes a clone of him thus, Jellien Patrick is born. All the rest of the Jelliens are (willingly) then captured by Jellien Patrick (SpongeBob caught one for himself, still thinking it's a regular jellyfish, and thought it was a new breed, because they didn't sting) and they both give out the Jelliens to the citizens of Bikini Bottom.
Afterwards, the Jelliens managed to take over most of the citizens except SpongeBob and Sandy who both learn that the Jellien's weakness is mayonnaise. They then fought through the Jellien army using mayonnaise and eventually took down the Overlord. The Jelliens were all destroyed, never to be seen again.
Appearances[]

Notes[]
- The name "Jellien" may have come from the words "jellyfish" and "alien".
- The Jelliens are a parody of the plants from Invasion of the Body Snatchers.
