The Sport Huai Snowball Sling was a popular game played by the Ko-Matoran on Mata Nui. The game involved 4 players, skating on ice, throwing snowballs at each other, which would stick to the player and eventually build up with each hit. When a player took too many hits, they would become engulfed in a giant snowball, and roll around on the ice. Winners would receive a Copper Mask Of Victory.
