Rick decided to make himself 12 again. It seemed like a good age. He wouldn't be a helpless or weak kid but not too old either. He'd be on the cusp of puberty, before complicated things began. So Rick thought he would not be treated like a little kid either. He could do proper mischief and go on more rides too. He would also gorge himself on junk food too. Sugar and grease and salt galore, because he knew his own metabolism would take care of it. At his age, obesity was not yet an issue. Moreover, it would be expected of a kid of 12 like him. Yeah, he'd enjoy all the fun things of being a kid. So he pressed the button, excited mostly, to better hide his slight apprehension. He would be his former self at 12, after all.
To his relief, the transformation was painless. The room became bigger and his clothes way too large. It felt very weird, but not that much unexpected or lasting. Rick was much smaller, after all. His perspective would be new and he would have to adjust to it. He jumped as a knock rang out on the door.
"Young man, have you transformed?" said a male voice.
"Yes," said Rick in a voice he barely recognised.
He had not heard that voice in a very long time.
"I see you've selected the age of twelve. I will let you some clothes outside and you can put them on. There's a changing room on your right. First door."
Rick thanked the man and waited a few minutes before going outside in his too-big clothes to the indicated changing room. He slipped out of his old clothes and grabbed the new folded garments. He donned them on and frowned. He was dressed in short pants, short-sleeved shirt, sandals and had a cap that all fit kids in the 1940's maybe, but not the world of today. He felt self-conscious and decided to call for help once outside. The employee from before appeared.
"Perfect," he said.
"Well, could I have other clothes?" Rick asked the man, now a giant.
"It's all you'll have but you can still have fun."
"But..."
"You'll be fine. You'll get lots of admirers dressed thus," he smiled.
He then grabbed Rick and pushed him towards a door that he opened. Rick became frightened. Oh no, he going to get molested! He struggled and shouted out his great fright but the man remained calm.
"Don't be ridiculous. We're sending you to the fay world. In exchange for magic, they like having transformed or regressed humans. Love to adopt you guys as kids or pets. You'll drive them crazy, especially dressed like that."
Before Rick could do anything, he was thrown out the door. A door that opened to a forest. Once he picked himself off the ground , he saw that the building, or resort even, had vanished, as if they never had been there in the first place. He was a kid of twelve, lost in a forest and the prey of creatures that wanted him badly.
