Showdown on the Ski Slope

Skiers and snowboarders have decided to prove to ordinary kids that they should play sports. But the ordinary kids did not give up easily: they proposed a snowball fight to prove who is tougher. Logically, the kids who play sports should be tougher, but what if that is not so? Prove how important sports are and defeat the team of ordinary kids. But be sure to move aside in time when someone comes down the slope.
