Did you know that in Japan, competitive pillow fighting is actually an official sport? The fules are simple. Each time start by throwing 10 pillows, aiming at the opposing team, trying to hit the boss in the opponent’s arena. Some team members can use blankets as protection shields. As soon as someone from the other team, hits you, you’re out and have to lay down.
