SpongeBob's next door neighbor and co-worker at the Krusty Krab, where he is the cashier. He hates SpongeBob and Patrick, and openly displays his hatred towards them, not that they ever truly understood. He believes he is an amazing artist and clarinet player, but quite the opposite in reality.
While his neighbors SpongeBob and Patrick are generally cheerful, Squidward is very irritable and unenthusiastic. He has a dry wit, and is constantly sarcastic. He is not very popular in Bikini Bottom due to his supercilious attitude toward those he feels are "uncultured".
Squidward is an aspiring artist and musician, though most of his art is created in tribute to himself and his music--his instrument of choice being the clarinet--is considered poor. It is revealed that an ancestor, Squidley, had cursed Squidward to be a mediocre musician when he decided that he would never be able to play the clarinet.
SpongeBob and Patrick consider Squidward to be their "best friend", though he has a strong disliking of the duo. While he has made his opinion of them clear, they either do not care or are oblivious, as they treat him as "one of the guys". Their antics and games annoy Squidward, but he will grudgingly participate if egged on or challenged.
Squidward works as the cashier at the Krusty Krab restaurant, only one room away from SpongeBob, the fry cook. He despises his job due to unintelligent customers, his skinflint boss, Mr. Krabs, and SpongeBob's enthusiam in working as a fry cook. At one point, Squidward quit his job; he was reduced to living in the street, leaving SpongeBob to nurse him back to health.
Squidward makes a cameo appearance in episode 12 of Tengen Toppa Gurren Lagann as a crewmember of the Dai-Gunkai.
