The horse that brings winter on its back. You can tell if it is that particular horse by the snowflake stockings and the royal blue cape that it dons.
Of course, many may try to fool others by dressing their horse in such garments.
But they could never replicate the snowflake trail behind it and that winter literally blossoms behind it, no?
Seeing it is rare, as it usually comes around late. But if you happen to catch a look at it, it will give you a wink, and good fortune may come your way.
