The Drabs are a group of creatures without color in Color World. A Drab that talks the most is the Drab Lieutenant, and the drab that Rippen replaces is Grayson Drabsquatch.
The Drabs are very cheerful and fun-loving, enjoying to rhyme and play. They used to dislike the Hues for having color, always trying to be better than them at everything. However, when Rippen steals all the color and both the Hues and Drabs look the same, Penn points it out and encourages them that they should be friends. Agreeing to it, the Drabs and Hues now get along with each other and are able to stop Rippen, save Penn, and get back the colors.
