4.Elephant Polo
The sport of elephant polo has been around since the British first went to India and adapted their horseback game to use elephants.
The rules are very similar to horse polo, except the pitch is shorter and the riders have a trainer on board as well (called a ‘mahout') to help control the elephant.
Originally a soccer ball was used, but now that has been replaced by a standard polo ball.
