Honker Muddlefoot, or Herbert "Honker" Muddlefoot Jr., is a shy, brainy, goose and Gosalyn's best friend. Honker is the younger son of Herb and Binkie Muddlefoot, and his older brother is Tank. Honker is neighbors with Drake Mallard/Darkwing Duck and is school mates with Gosalyn. It is strongly implied that Honker either figured out or some how discovered that Drake Mallard is Darkwing Duck off-screen, but how he met the Mallard family is never shown in the series. Due to Gosalyn's involvement, Honker often helps Darkwing Duck and Launchpad McQuack in solving difficult cases.
- Occasionally, when Gosalyn becomes the costumed crimefighter Quiverwing Quack, Honker becomes her costumed sidekick "The Arrow Kid."
- In the Negaverse he is a violent juvenile delinquent and often carrys a destructive weapon. He is show wearing a hat, black leather jacket and chains, a similar costume to Marlon Brando's in "The Wild One."
