As the snow lay round about (deep and cripsy and even) one wintry night long ago, a group of Monsters gathered around to construct the first coldman (snowman, for you human world types). They laughed and made merry, and rejoiced in the warmth of each other's company during this hibernal pastime. That wasn't the only thing that was warm, though - the frenzy and frolicking of the Monsters at play (especially the Fire Monsters) began to melt the coldman! To their utter surprise, as the powdery snow fell away, a young Monster carrying a handmade jingle stick emerged. At first sight of the Seasonal, the Monsters felt a surge of holiday cheer and goodwill towards Monsters. Thus was the Yool born, forever after celebreted as the keeper of joy to the Monster World, and enthusiastic participant in the Continent song.
