Synopsis by Hal Erickson
At the same time Gilligan (Bob Denver) has adopted a pet duck named Burton, the castaways' food supply has run dangerously low. Some of the islanders are all for eating Burton, while others would rather spare the duck in hopes that the mallard will be able to fly for help. Jealously protecting his new pet from his predatory fellow castaways, Gilligan dreams that he is a frontier sheriff slated for elimination by a hired gunman--played by Mr. Howell (Jim Backus). The familiar Gunsmoke sets are given a good workout during the dream sequence.
