King of the Box

I stomped back inside under the front door gap after roaming the block, ready to knock out whatever got in my face! Right in the hallway sat a fat, square delivery box, squatting there like an empty fortress. You think you're keeping me out? No way! I hauled myself up the rim on all fours, shoved the stiff cardboard flap down with a loud thud, and dropped straight into the middle. A thick wad of brown packing paper tried to puff up at me, so I gave it a double-fist stomp until it crunched into a solid, hollow throne. This bunker belongs to me now, and nobody's kicking me out!
