Glow Rocks are strange glowing meteorites that bombarded Earth. A typical Glow Rock is approximately four meters in diameter, glows green, and displays no motive power, seeming to drift with the wind. Glow Rocks seem to appear only over water, and may be drawn to human highways. (Note: The method by which the Glow Rocks imprisoned the other Go-Bots is unknown. Physical contact with Aerobot caused them to shatter... so that probably wasn't it.)
