You have heard of Vivian's Arcade in the Mall you always wanted to try to see what it is about, you are the very first customer.
You pay the fee and suprisingly you get a Gazillion Tokens for your measly few dollars, little did you know that there is a good reason for this. this arcade is not about the money, no it is about the changes, if you win you get a a Gazillion tickets for you to redeem on prizes, but if you lose there will be consequences, consequences that affect your body. If you lose your clothes will be destroyed and you will turn into a Naked Girl with your private parts exposed, and you will gain a Tail and either stay as a naked human girl or become a girl animal or if you are already a girl the only changes you will experience are your clothes being destroyed and your naked female parts being exposed to the public and either you will stay as a naked girl or turn into a girl animal, if you stay as a human girl, the tail will be a Naked Hairless Bareskin Human Tail. But if you turn into into a female Animal, then your tail will change into whatever animal it was. You will also gain whatever physical characteristics that animal has too, for example winged creatures get wings, dragons fire breath, fish lungs, reptiles scales, birds feathers, cows udders, kangaroos pouch. etc etc.
Although you do not realize it, this Arcade is very dangerous, you will have to play very hard and smart to keep yourself as a Fully Clothed Human without a tail.
