Duck (first name Skip) is one of Bird Brain's more recent henchmen. 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.

- It is likely that he'll keep appearing.
- Whenever someone says his name, other people "duck" for cover, because they think that something is coming right at them.
- In Puppy Unplugged, whenever Bird Brain calls him Skip, everyone skips around happily.
