Both Jon and Karyn have a blue glow around them. There ears slowly got longer, pointier...and a lot hairier as a thin coating of white hair covered their stretched ears. Soon, the short white hair began to cover most of their bodies.
There fingers and toes blackened and solidified into smooth, black hooves until they started wobbling on there legs, falling over with a loud CLACK of there hooves on the floor and stumbling out of their now useless shoes, shaking off their socks, there arms finally lengthening until they were as long as there legs, and thus standing in a full quadrapedal position.
Their shirts were now way too short with the long forelegs sticking out of the sleeves, and their face slowly began to bulge up, their noses disappearing while the nostrils enlarged, teeth growing inside there mouths and bose there whole face stretching out along with his teeth. Also, there eyes had severely bulged up by now and moved to the side of there heads, with their hair running down all the way down there elongated necks into a silverblond mane.
Their expanded horse butts had stretched there pants to bursting point, now both finally giving in after a bulge split a hole in the back with a loud "rrrrip", a long blond horse tail now flowing through the hole.
Suddenly, a pointy ivory horn began to emergy from there foreheads, growing to about a foot tall, still glowing with the same magical energy that caused his change. They were now white horses with a softly glowing white horn on there forehead. A unicorn.
Then the gender change begin and soon Jon is a female unicorn and Karyn a male unicorn.
Then the d10 dice effect occurs and both of them regress into new-born unicorn colts.
Then Jon's wish occurs and both are transported into the new reality.
