Among a rain of magic and mystery, Scott was bonked by a medallion that winked into him as a flash of purple-fuchsia light. The empty box and a few more-stable boxes bounced off him, causing him to...fall to pieces like a poorly connected doll? His head popped off his body to leave a flat neck, his arms and hands popped off his torso with similarly blank planes, his torso from his pelvis, and his legs from that, and his feet from his legs... he was a jumbled mess of mannequin-parts dumped in clothing!
In a burst of fear, he reassembled back together like a crash in reverse, holding the now empty box as the medallion had been absorbed as his clothes fluttered back into place.
Knock It Off
The Parts Finder
it said, in bright box lettering. "Sold something you can't live without? Missing pieces? Need to grow back that thing you're pretty sure people get transplants for? Pretty sure theft is illegal in your area? No problem! With the new Knock It Off parts finder, you can take things and they'll just grow back! Take people's stuff or parts, and nobody will care! Whether it's the clothes off their back, the head off their shoulders, or the junk in their trunk, it'll be replaced in short order or returned when you're finished with no lasting consequences. No worries about decay or getting stuck in a grate: spare parts can be stored internally or dismissed when no longer needed! Comes with free part separator, locator, attachment, and clone functions. Connect, share, disconnect, and replace whenever you need or want to: even abstract details! Make your friends think like you or share your sensations. Break apart and put yourself back together, or swap with better parts based on whoever you find for it. Better yet, copy the effects of a workout routine without needing to work out. Even bowling people apart can be ignored and undone with an act of will. You can even see what objects would be like as your new parts, full sensory package included! Try out your enemies' side of the appearance line, or take their whole wardrobe and let everyone ignore their new nudist kick until you ship in replacements. Don't just knock their socks off, you can both have a pair with the Knock It Off parts finder!"
The rest of the box was poorly-special-effects photos of people in various states of mannequin-like reassembly, a stereotypical thief stealing a model foot from a purse for some reason, and what appeared to be a starfish with separated limbs growing into a new starfish next to the original growing back with a corny "Like that!" text.
True to the details about thefts being replaced, a new amulet filled in the box. Scott set down the box on the shelf, tried to play the other stuff off as an accident, and fled a different direction trying not to think too hard about what just happened.
Something guided him toward the exit, aisles seemingly no longer an obstruction now that something special had happened. Hunger returned, unsubtle and insidious. The door out beckoned, and fear was great. Maybe this was all just a hunger-induced fantasy, or a dream, or cause to drive home...or maybe a chance to buy snacks at a vending machine or whatever.
