As you watch him and his face changes into a blending between that of him own face and a donkey, you feel a strange sensation just above your rear. You reach bach to massage the sore and find a lump ad the base of your tailbone. As you rub it trying yo see behind you at the same time you feel it grow larger intil with a tearing sound a part of you about 6 in. long appears through a hole in your pants. it starts out looking like your normal skin and has a tuft of hair growing out the end of it. As you feel it it grow hair all over it and gets longer by the senond until you are holding onto a foot and half long donkey tail. When you look back at the other boy his hands and feet have changes into hooves. In panic you see him run around the room in circles until he falls down onto all fours and his face changes to look ever more donkeylike. within seconds a full dinke it running around the room smashing things with his back legs.
Then the truth of what is happening hits you and you run back over to the strange mirror.
