There was nobody since the last bus left 15 minutes ago, so curiously if the ring can do wishes you wish that you could change your body to be the best for my mindset.
And so you looked at your body as scales began to form along your legs, turning your skin hard, but at the same time offering protection. Your legs zipped together, and their bones dissolved away to make room for new organs. As it forms, your new tail began to grow longer and longer to a length of 45'7" and 5' thick with muscles. Your hair grew longer as well, but soon changed into a mess of tentacles going down to the base of your back, and your human skin softened. You watched as muscles formed and three pairs of arms grew out from your torso which was soon followed by your upper torso growing thicker to match the thickness of your tail and your breasts growing to D cup breasts.
You looked into a mirror in your room to find yourself looking into a feminine face with slightly snaky features and yellow reptilian eyes. You looked in amazement at your beautiful new body that was yourself as you contemplated having another wish.
