Honkers come in a variety of colors, and baby Honkers are hatched from eggs. It is not known how closely related (if at all) the Honker species is to that of The Dingers, although there are similarities between the two.
As the Honkers never speak, their performers vary, depending on puppeteer availability. In the feature film Follow That Bird, Tim Gosley performed the Honker who served as Oscar's car horn. That specific Honker puppet has been known as Homer Honker, one of the few Honkers to have ever been named. Another Honker whose name has been mentioned is Henrietta Honker, the small pink honker.
Most of the Honker puppets were constructed with only one arm, built for the puppeteer's left hand. This arm is directly connected to the front of the body, but on the television screen, it is barely noticeable due to the amount of fur and fabric on a Honker's body, and the framing of the puppet on-screen.
