Role in series
SpongeBob says "Hi" to him, but due to his rancid breath, his skin subsequently disintegrates, and reveals 2 inside layers.
SpongeBob gets mail from him while he is working on his boating school essay. SpongeBob tries to waste time by asking him about where he gets his mail from, before he reminds SpongeBob that he has an essay to write.
He delivers the mail to Spongebob's mailbox
He comes to deliver the Kelpo toy package SpongeBob was waiting for.
Later, when Squidward is looking for a friend, he finds him, who says he is more of an introvert than a kidder. Squidward finds out he also likes toast points and fancy art galleries, but after he reveals that he hates clarinets, Squidward leaves and he gets upset.
He appears happily delivering SpongeBob's mail, apologizing there are no packages for him. He then mistakenly delivers the sea fleas that SpongeBob ordered to Squidward's house. Upon seeing Squidward's pink leg warmers, he reveals his own, saying they are leg warmer buddies. Squidward tells him to go back to fashion school, which he eagerly agrees to.
