Number 227 of Dr. Sinestard’s One Thousand Robocyclop Guards: Dormant. Was clinging to my jetpack when I made it out of the crater.
Warning: If Dr. Sinestard was not in fact killed by the explosions, this could potentially be remotely reactivated. I didn’t have proper shielding to remove its plutonium battery. Bids start at $9,999.99
