Cardboard Bunker

I crept into the dark cellar looking for the monster and boxes you spoke of. ...Hhh. No factory here, but three tall cardboard cartons waited beside the furnace! I lunged forward—WHAM! Clasped both yellow mittens around the rough brown cardboard. A dusty, hollow boom! Then the iron pipe clattered—CLANK! A sudden, vibrating rumble shivered the cement floor. Run? ...No. I stayed right there. I dragged the widest box flush against the warm metal, squished through the flaps, and wedged my long fuzzy limbs inside. ...Quiet now. Just me and the humming beast.
