Squidward's ex-girlfriend is an unnamed character who only appears in the episode "Love That Squid."
She has brownish-red pupils inside light yellow eyes. She has short, black hair, black eyelashes, and a curved nose. She also wears a light pink dress and a necklace with pearls. She looks similar to Squilvia.
After Squidward asks Squilvia out on a date, SpongeBob notices that he is nervous. He then asks him when the last time he went on a date was. Squidward then has a flashback showing him and his ex-girlfriend dancing together in a black and white theme, implying that they went out a long time ago.
