Description Edit Edit
Harold has a gray mustache and wears glasses. He is brown with dark brown holes. He wears a white shirt, brown pants, black and yellow belt, and a tall, white hat with a brown stripe. His head, along with his wife's, are much rounder in appearance than SpongeBob's, making them look more like actual sea sponges.
Personality Edit Edit
Harold usually seems to be a happy cheerful fellow who likes to take care of SpongeBob with his wife Margaret. He can also be a bit protective of his wife as seen in "New Digs." He does, though, seem to like to spend time by himself as seen in "BlackJack."
Biography Edit Edit

According to SpongeBob's thought in the episode "BlackJack," Margaret says "...it's so nice to spend quality time with you in the office all hours of the day," implying that he has or had, at one point, an office job.
According to Hooray for Dads!, SpongeBob gets his jellyfishing skills from Harold.
He currently lives with Margaret since SpongeBob moved out.
