ロボットのくにSOS

René pays a visit to Dr. Hoop to have his broken toy robot repaired. There, a real-life wind-up robot makes a surprise appearance and requests for Dr. Hoop to come and repair the generator that powers all of Robot Country–and the robots, too–saving them all. With the wind-up robot leading the way, the ragtag group makes their way 600 meters below ground—destination: Robot Country! (Source: Fukuinkan Shoten, translated)
