Wild West C.O.W.-Boys of Moo Mesa (Wild West C.O.W.-Boys of Moo Mesa #4)

Whoa, Nellie! It's time to call in the "calf-valry" as the Wild West C.O.W.-Boys of Moo Mesa ride into their rip-roarin' finale-and finally uncover the true identity of the mystery villain Dark Horse!

A horse is a horse, of course... unless that horse is the mysterious outlaw known only as Dark Horse, the steampunk-fueled menace bent on mutating the innocent townsfolk of Cowtown! Now, in their very first team-up, Marshal Moo Montana, Dakota Dude, and the Cowlorado Kid have saddled up to bring this rogue to justice. But hold your horses-this equestrian enemy may not be what he seems!
