Mr. Pirateson is the current owner of The Poop Deck, a fast food business seen in the episode "Friend or Foe." He is quite demanding, and comes off as rude sometimes. He can only say "Arrr!" Like Gary the Snail, the tone of his voice can give viewers a hint as to what he was saying.
He has a black pirate hat with a feather on top. He also has a light gray beard and wears a red coat with yellow stripes and a white handkerchief in the middle.
