This is an older series I did, kind of like an advent calendar where every day leading up to christmas the character became more of a beast until she was a reindeer for Christmas day.

She's been disappointed with life. She wishes for a boyfriend, but Super Elfie turns her down. She instead offers her a job and a belt. It's a uniform of sorts, but she can't take it off, and the jingling has a strange effect on those around her.

I have antlers! and I am the perfect specimen of a Reindeer there ever was.
