Johnny looked down at his feet. No change yet.
Ezekial Flint looked down at his feet. No change yet.
"Ok, when is this gonna work, brother?" Johnny asked.
"It will." Ezekial FLint said. "I know what I'm doing. We'll be feeling fishy soon enough. Trust me."
Johnny just stared speechlessly, as Ezekial Flint grinned. "Besides," he said, "When will you ever get a chance to do this again?"
Then, without warning, he grabbed Johnny, and then the two of them plunged into the sea with their clothes on.
It was then he saw his clothes - they seemed to be disintegrating; turning into bubbles, and floating off of his body, underwear and all.
"Well!" Johnny said incredulously. "My clothes are going away!"
he saw that his legs now joined halfway down his thighs, hiding his genitals.
Refocusing his attention on his feet, he found that he could not longer reach them, his legs were now considerably longer. The feet became webbed, and then, the smallest, outward toes were now the longest, and stretched the membrane between them and the other toes further. While he watched, individual toes faded away, leaving only the webbing surrounded on the outer parts by flesh.
Trying to move, he noticed the joints of his knees were no longer definite, and bent in any direction he chose. The separation between his legs continued to close like a zipper and merge into a single column.
Hundreds of goose bumps bulged on the skin of his legs, flattened, and pressed together, forming rough ridges. The scales mostly retained the old skin color, though they were tinted slightly a purpley-blue.
and then the changes on Ezekial Flint began as well: his legs were involuntarily drawn together, and his feet flattened and spread out, in much the same manner as Johnny's had. His feet blended together, and he could no longer separate his legs. They had joined together and become as one. The man watched as his clothes dissolved, following the changes to his body. He watched as what had been his legs extended another full meter beyond where his feet should end, and a fish tail unraveled itself. Scales appeared along the tail, thousands of them, tinged bright blue. He felt his privates recede behind a flap of skin, so it looked as if they had never existed.
"Holy carp!" Johnny exclaimed. "We're mermen!"
"Exactly!" Ezekial FLint said, wriggling the tail that was once his legs. "ye wanted to be part fish, matey, and ye can't get any more part fish than bein' a merman, could ye?"
