The forest swallows the last light, and the decaying lab breathes a musty chill. Dust motes dance in the beam of your flashlight as you find a glass case, its worn plaque reading "Instant Localized Weight Gain Inflictor." Inside, a softball-sized sphere gleams with dials, switches, and a rubber point. The moment you lift it, a small screen flickers to life. "Please place rubber contact point to subject's desired area to begin." The device hums in your palm, waiting for your decision.
