Picture in me the ravening beast and you’ll have a sketch of my character; though I’ll warn you it is not I who stalks deadly in the night, looking for soft flesh on fleeing feet and the taste of fear. I save my prowling for the scullery door and the elusive glow of the hot oven. I am the Thing That Scuttles, the Devourer of Grains, a card carrying member of the Cheese Sanctification Society. (Progenitor of Pestilence, too, if you want to get fancy). Stop up your cracks and close your cellar doors. Anything less than a full lock down I consider an invitation. There are no spells to keep me away for long. No beauty dares kiss my lips and try to change me. Isn’t that grand? I know of no creature more comforted by their own monstrosity than I.
This was a very silly poem. I don't know where it came from, but...well, that's poetry for you. PS: If you get the "Cheese Sanctification" joke, you win a lot of virtual points!
