Squilvia is considered a minor character, as her role, along with her pairing with Squidward, is limited for that one episode only.
Squilvia has brownish-red rectangular pupils in light yellow eyes that are slightly brighter than Squidward's. She has short black hair, black eyelashes, a curved nose, and dark pink lips, and is a slightly different shade of blue than Squidward.
She wears a pink dress with ruffle tips and carries a velvet purse. She talks in a poetic style.
Role in episode
She is seen entering the Krusty Krab ready to place an order. She finds the decor quite interesting. Squidward immediately falls in love with her and tries to talk to her, but is too nervous. SpongeBob helps him and tells Squilvia about Squidward. Squilvia agrees to go on a date with him.
Unfortunately for Squidward, it has been a long time since he last went out on an actual date, but SpongeBob offers to help him by setting him up on a "practice date." However, this goes terrible, causing Squidward to yell at SpongeBob to stay away from him, but then he turns around to see Squilvia standing there, and she admits that she witnessed the entire exchange.
At first, Squidward assumes that Squilvia will not go out with him since he acted like a jerk to SpongeBob, but Squilvia tells him that she actually likes him even more, admitting that she thinks a "guy who can't take fools lightly is 'totally dreamy.'" She then tells Squidward that they should go eat, much to his joy.
Squidward is Squilvia's appointment in the episode "Love That Squid." Although they are shown to love each other at the end, they have only been together in that one episode.
Squilvia is a portmanteau of "squid" and "Sylvia," the latter being a female name.
