Crowd pummelers are cheap and easy-to-maintain devices made for sentry duty. These constructs are made of red pipes and pistons, and have one green robotic eye that they use to watch the area around them. The gnomes of Gnomeregan used these robots to patrol their streets and bash anything they notice that violates the laws programmed into them. Since Gnomeregan's fall, most are programmed to attack anything that is not a leper gnome.
