you work for the Coast Guard. Making a detour along the seashore at a late hour, when the stars were shining in the sky, and there were only small ripples on the water from a weak wind, you noticed something unusual in the distance, near the rocks. As you approached, you saw the body of a man covered with terrible wounds and... a fish tail!

The man was lying on the sand unconscious and bleeding. You urgently needed to do something, otherwise he would die!
