The Jellion Clones look almost exactly the same as their Bikini Bottomites counterparts, except for a few traits. They have big, black eyes with white pupils and sharp teeth that are spaced from one another (even Jellion Patrick doesn't have Patrick's one tooth). Aside from those, the Jellion Clones look like a mirror to their counterparts and can fool anyone into thinking they are normal citizens.
The Jellion Clones are created when regular Jellions, which the Evil Alien Jellyfish Overlord already made, attach themselves on top of the host's head, then squirt out a Jellion Clone in its place. The Jellions then take the real copies away where the Jellion Clones live out their lives.
After SpongeBob and Jellion Patrick gave away Jellions to everyone, the Jellion Bikini Bottomites started to take over. Like all Jellions, they have big, black eyes and sharp teeth and talk in a slow manner. They spend most of their time at the Krusty Krab ordering Krabby Patties without mayonnaise.
Behavior and Weakness
The Jellion clones talk in a slow, monotone matter much like how aliens would talk. Some of them, mainly Jellion Squidward, would sometimes end their sentence with a "RAH" like sound. They even seem to act like their real counterparts, such as eating Krabby Patties. However, when someone mentions mayonnaise, they act extremely aggressive and attack on sight. They also seem to hiss and point at anyone that mentions the condiment. This is because mayonnaise is their one and only weakness. If touched by mayonnaise, the Jellion clone will melt into a pool of green slime and the bodies which they took over will wake up.
While lacking any ability to creating Jellion clones, Jellions Clones would attack in droves and fight to death for sake of Overlord's safety, as seen when they surrounds and tries to attacking SpongeBob and Sandy even if they eventually killed off by both of them with mayonnaise.
The Jellion Bikini Bottomites' real behavior when no ordinary lifeforms around much different compared with their real copies. They mainly like mindless zombies which, of course, are made to serve the Overlord. They also seem to enjoy hissing, espically when someone mentions mayonnaise. They also appear to walk very slowly like zombies but can also run very fast as they were chasing SpongeBob out of the Krusty Krab.
Given that they cannot create clones unlike Jellion Jellyfishes, the serves as Secondary Jellions whom
