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 that throw knockout punches at the sound of a bell so Second Banana can't lose.
- Second Banana is sporting a redesign in this short that he would have for the rest of his appearances, his ears are shaped different, and rather than a green bow tie, he wears a yellow turtleneck sweater. Additionally, Merlin doesn't wear spats on his feet anymore.
- This cartoon opens with a unique one-time variation of Bill Lava's arrangement of the Looney Tunes theme ("The Merry-Go-Round Broke Down.")
