Merlin the Magic Mouse and his sidekick Second Banana travel to the Old West town of Rattlesnake Gulch. A tough guy exits a saloon and challenges them to a fight. Merlin bets him that Second Banana will win, and schedules the fight for the next day. That night Merlin enchants a pair of boxing gloves so Second Banana can't lose.
Merlin is a caricature of the actor W.C. Fields.
