Your name is Melissa. You are 16 years old, single and live with your mother and older sister Sam. Your father passed away before you were born, and your mom has had no intention to find someone else. One day, you wake up and find a strange box next to your bed. Inside is a ring and a note that looks like it's been written 5 minutes ago.
"This is the Ring of Swap. It can swap any body parts between two humans, or a human and an object that could replace the body part. Clothes can be swapped with clothes or body parts. It can also swap two parts on the same body. This also means that the parts don't need to be matching. No matter what, swapping two parts will never kill anyone. Once you put the ring on, it will fade in your body, and you will gain it's powers until you die. You can choose who is aware of the swap. Have fun with it!"
'Ring of swap? That can't be real.' You think while putting the ring on your finger.
'It looks good...' You think when the ring suddenly fades away. 'Was it a dream?' You thought as you stared at the box with the letter still there.
'Swapping body parts, does it really work?' You thought while concentrating on your two hands. Suddenly, something looked off about them. Then you saw it, your hands were swapped!
"No way, it actually worked..." You whispered in amazement. You concentrated again, and suddenly they were back where they belonged. You were going to have some fun with this...
"But first, one crazy test just to make sure." You said while concentrating...
Suddenly, your right foot was attached to your left arm, and your left hand to your right leg! You tried walking for a bit. But after a few steps you swapped them back because you nearly fell.
