One day you were sailing on the sea and you saw a waterman splashing around in the water not far from the ship.

The waterman looked beautiful. You had the urge to catch him, which you did!

At your command, the sailors fished out the waterman. You stare at the waterman, noticing him waving his tail slightly in your direction.

You've heard rumors that watermen wave their tails to attract attention to the object of their interest that they want to mate with.
