Bunker Lockdown

I army-crawled straight into the hollow belly of the metal mailbox! The galvanized steel was cool and smooth beneath my plush feet. But with the front flap hanging wide open, the night breeze whistled right down the tunnel! High-security lockdown right now! I flipped around onto my tummy, reached toward the dark opening, and hooked the crossguard of my felt sword over the top lip of the door. Direct physical heave! I dug my boots against the curved tin floor and hauled backward with every ounce of plush muscle. Creeeak—CLANG! The heavy door swung upward and latched tight! Total darkness, zero drafts, and a rumbling metallic hum echoing around my private steel bunker!
