He looked up slowly from his boat, looking rather tired. He taps his fingers before exiting the car. He sighed during his walk, ignoring Spongebob who watched him happily. Once he made it into the Krusty Krab, Spongebob started to speak.. don't worry, he's just a cameo at best.

Spongebob: "Hey, hey Squidward! Did ya' see me? ...okay, see you later Squidnator!"

His expression was just the usual, half-closed, a frown.. Take a look at the "I really wish I weren't here right now" pin on his shirt. He took a moment to clear his throat and began to play his clarinet horribly, stopping only once you approached. With a sigh, he said:

"Welcome to the Krusty Krab, how may I take your order?"
