Herb and his wife look similar. He has a large walrus-esque dark gray mustache and is coral pink with red dots. Just like the rest of the Star family, his pants are the same as Patrick's but he wears a shirt that has a mauve color with light green flowers. He wears the same colors as his wife and his son Patrick.
In "Chocolate with Nuts" he appears without a mustache and his shirt has the same colors as Patrick's pants, and looks almost exactly alike compared to his son.
He and his wife appear at the end of the episode. Squidward comes over to Patrick's house to say that Patrick's parents have been repeatedly asking, "Where's Patrick?" Patrick hugs his parents and they are impressed that he can do basic tasks like getting dressed.
He is one of the many customers of SpongeBob and Patrick when they are selling their chocolate bars. Patrick tells him that chocolate bars will "keep you from getting any uglier." He buys some, telling his son "Just in time!" In this episode, he appears without a mustache and he looks very similar to his son.
