From the publisher's website:

Oh, give me a home where the Jackalopes roam And the Dudes and the Buckaroos play, I'll slay and I'll loot, give the monsters the boot, And the dice are not loaded, no way. The Good, the Bad, and the Munchkin opens a whole new frontier – the Wild West! Forget dragons and goblins – Jackalopes and Davy Croc have just as much treasure. Those plains may seem wide open, but there's lots of monsters to kill, and lots of stuff to take. Become a Cowboy with a Twenty-Gallon Hat, or an Indian on a Catamount. Fight Wild Bill Hiccup, the Killer Jalapeño, and a Barber Shop Quartet. Take The Annual Bath for an extra level. Or just pal around with your sidekick the Greenhorn, until you sacrifice him to distract a monster.
