fence, any player can call out "watermelon". If the ball goes over the fence, those players gain a "life". If it doesn't, they lose one. "Watermelon" must be called out before the ball is within a short distance of the fence. There is also a "freeze" rule used in some occasions (in some places it's renamed "challenge", or "reach"), wherein whenever a player catches the ball from a long distance away from the wall, any other player may call out "freeze", meaning the person who has caught the ball must stop where they stand and throw the ball. When reaching the wall is impossible for the player, some games allow for the player to call "relay" and pass the ball to a player within reach of the wall. An American variation of this rule allows the "frozen" player 2 options: throw the ball and risk a life on if it hits the wall, or drop it directly onto the ground below them and run for the wall.
