Jellion Squidward was created after Jellion Patrick jammed a Jellion through Squidward's mail slot. Then, the Jellion consumed him. Thus, Jellion Squidward was born. After that, on the next day, Jellion Squidward took Squidward's place on the register at the Krusty Krab, serving other Jellions with Krabby Patties without mayonnaise. However, one of the customers wanted mayonnaise, to which, Jellion Squidward and the other Jellions viciously hissed at the lone customer. Jellion Squidward was defeated after SpongeBob and Sandy took down the Evil Alien Jellion Overlord.
Like most other Jellions, Jellion Squidward behaves much differently from the original. First off, Jellion Squidward seems to smile a bit more than Squidward and most of the other Jellions except for Jellion Mr. Krabs. Jellion Squidward is also known for his "Rah!" like catchphrase, and says it usually after he serves his customers Krabby Patties without mayonnaise. Also like Jellions, whenever someone mentions mayonnaise, he reacts hastily, knowing it's his true and only weakness.
"Do not let the bed bugs bite! Rah!"
"There will be plenty of biting this night. Rah."
"One Krabby Patty, hold the mayonnaise. Rah."
"Thank you, come again. RAH!"
"Yes, and you can use this Jelly as a pillow."
[along with Jellion Mr. Krabs] "Sleep well!"
Jellion Squidward may be the second Jellion the Jellion Clones ever created.
Jellion Squidward often says "Rah" at the end of his sentences.
