A Shake of the Bells

Wait... wait, what? I can... unclench? My fingers, they actually move. I shifted my weight, and the jester hat tipped—a soft jingle right against my ears. I stumbled back a step and bumped against that cardboard block marked with a 'B'. It's solid. Everything here is solid. Where... is there a door somewhere? I hugged my hands close to my chest again, watching the room, staying right where I am.
