Not really creepy, but while I was at my new house last week, I was still there at night time, and I happened to open a window and I could hear this munching noise right outside. There was no moon (cloudy) and all I could make out was this vague black shape that very slowly moved away, munching all the while. I was thinking, what the hell is it?? I was about to leave in a few minutes anyway, so I backed the car around that part of the house and I could see it was a big black wombat. Nothing to worry about at all! It ran down the driveway, out the gate and jumped into a drainage ditch just outside. I closed the gate on the way out. Hopefully that wombat doesn't get run over some time, they have an unfortunate habit of wandering onto roads and they can get quite large.
