Little did Ben know that when the website encounter the "Under Construction" error that a glitch occurred, associating the style of hairyness with one of the further options on the page... Becoming Bigfoot.
Suddenly, as he stood in the woods, he found his mind clouded with more primitive thoughts, making him feel more inclined towards nature and living of it. His thoughts made him feel turned off by the outside world that embraced technology and want to avoid it all together.
He rapidly changing mentality began to worry Ben, making him want to rush home before whatever was taking place could finish overtaking him. However, he felt panic run through him when he felt his forehead sloping back, similar to a primate. Then his muscles started to spasm and scream, causing him to fall to his knees. He wanted to cry out for help but all that came out were indistinct grunts and inhuman cries.
As his change progressed, his shoulders became broad and his torso became lean and fit, his chest forming pecs. As his body swelled with a fit muscular physique, he found his former self cursing ever having gone to Key-ed Changes and messing around with it. However, the new side of him emerging from the changes was absolutely excited about how we would now finally be able to turn away from normal society and live as a hairy creature living off the land and nature, not needing anything else to survive.
While the changes neared their end, his feet became enlarged and his penis throbbed with pleasure. The throbbing pain soon seized over his body, coming to a close. At this, his anatomy ejaculated with release as he let out a animalistic call, announcing that he made finished his transition. Standing on his two huge feet, Ben gazed around him and beat his chest as he grunted in contentment. He was now Bigfoot and ready to embrace his new lifestyle.
