Walk on water:
Enable the "Turbo mode" code and begin game play on the first Ice Hit level. Get dropped off by the boat, then hurry over the boxes and the fence. Then, run around the fence to reach a road. Turn left, go towards the river and stop near the edge. When the boat comes around, jump on it and stay aboard to travel into the tunnel. Although your character will fall off the boat, he can walk on the water, as if on land. Keep waling all the way to where the boat traveled to reach a white screen.
