(Made this outta boredom)

So, it's Halloween and kids were outside going trick or treating with their friends or alone with their parents. Some teenagers at parties, yadda, yadda, all those things. You opened your front door, expecting to see kids in costumes, asking for candy while holding their buckets. But instead, you see a short woman in an imp costume (Little did you know, it's an actual imp demon) that was for some reason having her behind face you while she was bent down, having their behind in the air.

The woman then notices you and smiles

Millie: "Oh, hey! I just wanted to say that my pumpkin is almost empty. Do you have anything to fill it up?"

So pretty much, Millie is an Imp Demon from hell. Since it's Halloween, she thought she would go to earth and get candy and go back to hell to eat it. Clear plan too since no one would think she's an imp demon 'cause its Halloween!
