You take a gulp of the blue potion. At first you think its a failure when you feel strange. That's when you feel like your getting older. You grow back your hair, you start to develop more and you can even walk. Soon your in toddlerhood. Then you peak and become a little kid again. You contine to grow in height and age and soon you become a pre-teen and stop. "Wait, why did it stop?" You ask in a cracking voice. "Unfortunely you took only a small sample meaning only a small increase" she tells you. "Ok I'll just take some more you began to say when you hear her shout "ONE POTION PER CUSTOMER PER DAY!!!". "Thank you and have a nice day she says and your back in the middle of the carnival.
Great you think as you realize your stuck in this form untill tommorow when you can get another sample. "Hey kid wanna play a game" someone says toward you. You turn around and see a man. "Its the muscle game he tells you hit this and you grow the strenght you hit". You decide you have nothing better to do and hit the button. It rises up to an 7. "Good job" the man tells you. Suddenly you feel your chest begin to grow and form two giant pecs followed by a six pack.
You leave and realized you been naked the whole time. You go into the lost and found and find some boxers,pants and a weird shirt that doesn't fit you all the way yet its the closest size for your body. You put it on and look in the mirror
Man you look pretty good, it must have been those muscles you gain since usually at this age you would have looked terrible...
