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?
