This was directly based on something that I had penned in a dream last night.

I was in some sort of dark location, where a deer standing on two legs would try to chase people. There were cabinets I could presumably hide in (I never tried it). The deer would sometimes check inside these cabinets. If it found any food in it, it would eat it all until it finished what was in there, too distracted to continue chase until it finished. Of course it would fatten a bit over time.
