Swim your way to victory in the perilous depths of the ocean.

Your diver will tend to sink to the ocean floor, so make sure you keep him afloat by pressing the space bar.

Try not to hit rocks, other objects or animals, as they can slow you down, hurt you or kill you.

In particular look out for sharks - they are quick and very good at biting people in half.

If you feel daring, you can try getting a lift on the back of a dolphin, but there is no guarantee it will help you in the race!
