When Mungo Baobab discovers a valuable fuel source on the distant planet of Biitu, the Empire dispatches a gigantic evil Droid called The Great Heep to capture Mungo and take control of the planet. Arriving on Biitu to meet their new master, R2-D2 and C-3PO are shocked to find that The Great Heep has turned the planet into a wasteland and has handed Mungo over to the agents of the EMPIRE. With the aid of a small boy named Fidge and his pet, Chubb, the Droids devise a daring scheme to free Mungo, defeat the forces of the Empire and liberate Biitu from The Great Heep - forever.
