As soon as I made my wish, I felt myself contracting while fir started sprouting. My hands turned long and thin, my nails turning into claws. The same thing was hapening to my feet in my now too big shoes.
My nose extended out into a whiskered muzzle, my front teeth grew and my ears grew large. Finally a long hairless tail snaked out from my spine. I was a 3 foot tall wererat.
I stepped out of my shoes, climbed out of my pants and gnawed my shirt and jacket until they were stripped down to my size. Then I pondered what to do with my new form.
