You were in the ocean, on summer vacation.

It was night, the tide was low, your feet were in the water, when you saw a ripple. Right in front of you. Then another, then another, before right beside you, on the rock you were sitting on, a man breached the water.

He looked majestic, pulling himself up. You noticed he had gills on his ribs.. webbed hands.. thin, fish-like ears.. a tail.. purple and lavender sparkling scales... You stared in awe, until he saw you looking and got scared, flopping back on the water on accident with a 'hmph!'
