Use the rules from Ultimate Frisbee (move the ball down the field by throwing it, the player may take two steps after catching ball, interceptions or missed passes result in a turnover), but replace the frisbee with a water-soaked Nerf soccer ball. Not an extremely wet game, but the water gives the game a new twist. We used buckets as goals at either end.
