Dr. BadVibes decides to toy around with the idea of creating toy size robots and programmed them to steal items from the homes of the children who own them. Brian O'Malley gets one of the robots for his birthday. Named "Rocky", this robot went and stole a family heirloom, a leprechaun statue passed down from LongArm's great-grandfather and ran off with it. Brian followed the robot to where Badvibes set up his hideout at an old abandoned toy factory right near the sewers. There, he was captured and is held captive by BadVibes, who wound up arguing with Buzzbomb over the share of the stolen loot, hurting his feelings in the process. Brian must talk Buzzbomb into releasing and helping him, Sundown, and his father put a stop to BadVibes and his army of thieving robots.
