Duck (first name "Skip") is one of Bird Brain's more recent henchmen introduced in Puppy Unplugged. He is a duck who has not spoken in the series thus far, except for when he said "quack" and when he told Bird Brain his name. He is not to be confused with Quacky the Duck. He is voiced by Jeff Bennett.
