Lisa and the kid were enthralled by the happening to William, they didn't notice the similar changes each of them were going through.
Lisa's feet molded together as goosebumps formed to create a golden tail 6 feet long. Her hair changed to a shiny golden blonde as her breast went from a modest 38c cup to 44DD's.
Olli's feet were conjoining to create a Ruby red tail as his hair grew to past his shoulder turning a fiery Orange. His slim 10-year-old body buffed up as well.
Andi's feet combined as the goosebumps she felt turned her tail into a royal plum purple. Her hair grew down to her tail and turned to a dark-foresty green. Her breast grew to a youthful 38AA.
As the change took there final effect on the family. A truck pulled up and a strange Chinese man stepped out.
"Ah, congratulation on winning this special pool. I see you jumped right in and the transformation has taken effect." the family finally notice that not just William has transformed into merfolks. "Since you have changed, I have a proposition for you? I will make your lives wonderful if you will be a part of my zoo of exotic creatures."
" Why did you do this to us?" William asked confused.
" I did no such thing, it was fate that chose you to be as you are. I simply set fate in motion and here you are, again congratulation. Please come with me I have tank truck for you to ride in." Mr. Fu said smiling.
