You look down at your hands, or should I say paws, as they are covered in white fur. You now appear to have a tail, and very large ears in proportion to your size, which is smaller than Donald's thumb.
"Looks like the experiment had a few side effects after all" you
say to the clown, but all that Donald hears is a brief "eek!" He holds
out a small mirror to you which confirms that you have indeed turned into a
white laboratory mouse.
Do you sniff around the room for cheese? Or go down a nearby mousehole?
