Santa has invited all of the characters from the Cartoon Network shows to compete in a snowball fighting tournament! This is going to be the best Christmas ever says the Ice King from Adventure Time. When you get to the team selection screen after the intro pick your team from your favorite show or just who you think will be the best for a snowball fight. Pick up snow balls and then toss them at the opponents on the opposite side. Turn all their team mates into snowmen and you will win the match.
