Far across the universe, seven coloured bells, known as the ‘Rainbow Bells’, shine in the night sky. As long as they continue to ring, peace will prevail in the universe. One day, the evil scientist Dr. Warmon steals the seven bells and divides them up among his foot soldiers. And to keep himself company Warmon kidnaps Princess Melora. Without their sacred bells and their precious Princess the people lose all hope for the future. When the good Dr. Shinamon realises what’s happened he summons Twinbee, Winbee and Gwinbee to recover the sever ‘Rainbow Bells’ and to rescue Melora.
