However, trading his comfortable desk chair for the back of a bucking horse brings a whole new set of hilarious challenges. You will hit the dusty trails with Geronimo, Thea, Trap, and Benjamin as they try to survive life on a real working ranch. From herding rowdy cattle to learning how to ride cowboy-style without falling off, the action never stops. Grab your ten-gallon hat and join the Stiltons for a rootin-tootin adventure filled with big laughs, wide open spaces, and plenty of western thrills.
