Steve loved the water and we got him a snorkel and goggles.   One warm evening in Seattle, he begged us to take him to Carkeek Park on Puget Sound so he could swim.
Steve was born with some abnormalities on his right hand and left foot.   However he had an extremely developed sense of humor.  
As more and more families came to watch the sunset and walk the beach, their attention was drawn to the splashing and activity off shore.  It was Steve out enjoying the water.
When he finally came in, some younger kids came running up to him as he walked out of the water.   They gasped when he took off his flippers and they saw his foot and hand.   Who was this creature they wondered.    This happened in the late 60's or early 70's, and there was a neat TV program called Man From Atlantis.  
Steve laughed and told them he WAS the real man from Atlantis and his body had just not made the metamorphisis back to regular human all the way yet.
