Hindering Hands has an advanced memristor brain developed by mimicking the central nervous system of a ghost crab, then teaching it that anything humans want to solder is its prey.
its usual mode of operation is to pretend that it's just a passive novelty Helping Hands with positionable claws, and allow you to use it to position your work pieces. once you have handed your work to it, it makes a break for it.
once the humans get wise to this, it settles into being The Shopcrab, skulking in the corners of the lab and evading human sight, waiting until no one is looking before climbing onto the workbench to steal important items. in addition to its very fast scampering speed, it is also capable of a nearly three-meter vertical jump, and has electromagnetic feet capable of sticking to ferromagnetic surfaces.
the shopcrab periodically sits on electrical outlets to charge its batteries. in this state, its entire exterior is live at the mains voltage, and thus dangerous to touch bare-handed. if touched and not instantly recoiled from, the shopcrab will rapidly disengage and flee to find another outlet. the shopcrab is strong and dextrous enough to pull plugs and safety caps from most outlets.
a shopcrab can live for around five to ten years before its internal battery becomes too worn out to keep it running, at which point it dies. a dead shopcrab can easily be returned to life by replacing its battery, which is easily accessed via the bottom plate, but for whatever reason, most owners opt not to do this.
@diodelass I'm convinced, where can I acquire a shopcrab?
or is it an ancient summoning-ritual type deal
