As the magic takes hold of you and you start to transform, the fat witch studies you with interest. It seems she just cast a random spell at you in rage without knowing what it did, but you are both about to find out...
You start shrinking, your clothes being replaced by black fur. You feel a long tail snaking out of the base of your spine, and see whiskers growing from your face. Your ears change, migrating to the top of your head and your hands and feet turn to paws. By the time the transformations finish, you have become a small black kitten.
