"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?"
SUDDENLY!
Johnny could feel pains on his body. WELL, THE TOP HALF, ANYWAY.
First was at his head; his small beard somehow receded into his head, and his hair grew longer.
He then soon felt all the hair on his arms FADE away, and his fingernails became like that of a woman's.
SUDDENLY!!! AGAIN!!!
His voice began to crack, suddenly becoming feminine.
"OMG!" he said, in a voice that sounded half his own and half female. "What-what's happening to me?"
Suddenly, he developed sharp pains on his body. His waist & hips shrunk and huge breasts developed.
And and then the changes on Ezekial Flint happened as well. They were exactly the same as his brother’s.
"Wow!" Johnny said, admiring her new self. "I'm a mermaid!"
“So am I!” Ezekial Flint said as well.
