Klutz: Invasion of the Bristlebots
Invasion of the Bristlebots comes with two mini-robots - basically motorized toothbrush heads. These guys zoom around like caffeinated cockroaches, spinning, skittering, and bouncing off walls. Resistance is futile. The book bristles with ideas for robot games and activities: race robots against each other, use the included punch-out walls to construct a bristlebot maze, stage a robot sumo-wrestling match. You can even customize your Bots with the provided wire legs, feelers, and beady eyes.
