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.
He is indirectly mentioned along with his wife as "parents," in which it is revealed that Patrick's parents kicked him out and forced him to live on his own.
"I'm with Stupid"
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 their son is. Patrick hugs his parents and they are impressed that he can do basic tasks like getting dressed.
