Some days later, Johnny and Horatio came by Horatio's Island for a swim.
Johnny went below deck and changed into his swim shorts. Horatio went down after, and he changed into his white vest, and blue swim shorts.
They went on deck, and then, Johnny and Horatio jumped into the water.
They spent all but of 30 minutes in the water.
Suddenly, they both began to feel a tingling, then a numbness in their legs. They got onto the sandy beach of the island, and then, it happened.
Horatio saw his legs stick together, and he could no longer separate them.
His webbed feet fused into that of a huge tail fin.
His swim shorts disappeared as Hundreds of goose bumps bulge on the skin of his legs, flattening, and then they pressed together, forming rough ridges. The scales became a pale aqua blue.
Horatio took off his wet vest, and saw he now had a fish tail in place of legs! "Holy cow!" He exclaimed. "My legs have combined and fused together to create the vision of a aquatic fish tail!"
And then he saw Johnny had the same green fish tail that he'd once had when he swam with his son Ryan.
The 2 merfolk swam the rest of the hour in the sea.
