Many believe that the story first began in America in 1877, when two friends were arguing over whether a horse ever had all four feet or hooves off the ground when it galloped.
But there's still one lonely pony who believes in unity amongst all with hooves, and that's Sunny, who was raised to cherish the historic bond between all ponies, whether winged, horned, or otherwise.
Game pieces were carved from the antlers, rattles were made from the hooves, warm stockings were made of the hocks of the moose, moose hair embroidery made beautiful clothing.
But as the rumble of hooves filled the air, they moved aside, wary of the approaching horses, they watched the riders gallop past, leaving a trail of ice behind them.
The fastest land animal in the western hemisphere, the pronghorn antelope is built for speed with specially adapted cushions on their hooves and large lungs to help them take in extra oxygen.
Their hooves have adapted to the season, turning hard and sharp in winter, allowing them to dig down to the last remaining food - lichen, buried under the snow.
