Earth, Sea and Air

We made a game very funny with the ball, but we have to be very focused. One of us takes a ball and has to say: earth, sea or air. Who receives will say the name of an existing animal on earth, sea or air.

If we give the wrong answer or repeat a name we are out out the game!

 Seems easy, but it is not!! We have to be very quick to think and give the answer!!
