You run over to a relfective surface and examine your new face. You're now a 12-year-old girl with long red hair and freckles on your face. You look down and see that you're wearing a yellow tank top, denim skirt, small fanny pack, and white sneakers.
As you walk away from the mirrior, you think that you really should leave and try to tell the police or something about this place, but the desire of being a kid again is too strong. You're going to stay, at least for a little while longer.
You think you should probably explain to the girl who's life you just stole. You run back into the Merry-Go-Round and find the horse that use to be you.
"I'm sorry about this," you say, "But the only way to escape is for someone to sit on you. If you concentrate real hard, you can even chose the body you want." You mention to yourself, "I use to be a 20-year-old man, so this choice was really desperate. But, good luck."
You run out of the Merry-Go-Round and walk through the Carnival again.
