Jellien Patrick greatly resembles the real Patrick Star except for the dark, reflective, round eyes. This is a common trait for the rest of the Jellien clones.
Jellien Patrick was created after the Evil Alien Jellyfish Overlord created a jellien after eating a jellyfish then having it eat a sleeping Patrick and then carried him away. Jellien Patrick then meets up with SpongeBob who spots that he caught a jellien thinking it was a jellyfish. Jellien Patrick then catches a whole school of jelliens. He then tricks SpongeBob to give them away to his friends. After turning Squidward into a Jellien, Jellien Patrick then works at the Krusty Krab where he helps serve Krabby Patties, without the mayonnaise. He was then finally destroyed after SpongeBob sprayed him with mayonnaise when Jellien Patrick and Sandy were about to take on the Evil Alien Jellyfish Overlord.
Jellien Patrick behaves very differently from Patrick. His only course of action is to plant jelliens on the heads of citizens and turn them into Jellien Clones. Like all jelliens, Jellien Patrick extremely hates mayonnaise as when SpongeBob tells him that he was going to get more in the back, Jellien Patrick quickly turns his head around (with his torso still facing the grill) and loudly shouts out "NO MAYONNAISE!"
"Yes. I too have caught many jellyfish. Perhaps we shall give one to each of our friends."
