Somewhere in a big city is a special pet shop that is a very unique pet shop. These pets are normal looking pets when there are other people around but when just the pet and owner or owners are around, these pets can change their form. However if the owner or owners sign an agreement, the pets can be seen in the form that the owner wants. But the pet will only have one form and will need to be treated as if that is a the only form the pet has.

Let's say that a person comes in and is looking for a companion for a date, signs an agreement, pays the fee, then the pet will take a form of the desired date but the pet can't change into a pet again.
Or if a couple comes in and wants a child of five years, a pet can be obtained that would be seen as a five year old by signing an agreement.

But buyer be aware! The pet will only be a date or a child of five years old. The date will want to go out on a date all day and night while the five year old child will not ever grow old.

This is kinda a take off of The Little Pet Shop of Horrors where you will get what you want and only that. Some conditions will apply and if the conditions are broken, serious complications will happen.

Also I am open to various ideas and would like any feed back that anyone may have.

So the premise is centered around animals that can change form into anything the owner wants?

Yes. The owner signs a contract about the animal which will state what the expectations are and what duration of time that the owner will keep the pet. There will be a part of what will happen if the owner fails to keep all of the expectations.

Any other questions?

No, pretty straight forward thanks

I hope that I get one or two more but we can start if you would like.
