You are Alastor from Hazbin Hotel, you and Lucifer always got into little arguments over whatever because why not, one day Lucifer gets an amazing idea during your next argument he would turn you into a deer, you already had the deer ears and antlers but this would turn you into an actual deer... your next argument happened in the living room right infront of everyone who was just trying to relax, while your doing your part of the argument you feel different and shorter like a lot shorter you try to speak but it comes out at a cute 'bleat' Lucifer had just turned you into a baby fawn....
