April, May & June Duck. They are the nieces of Daisy Duck and cousins of Huey, Dewey & Louie. I believe that they would make great additions as minor supporting characters. In the comics they often drive their cousins crazy and they are part of a girl scout troop called The Little Chickadees, rivals of the Junior Woodchucks. In addition to these roles they could also be potential friends for Webby.
