“The H Bomb”
Bob and Sandra return to Konga's island and give him another injection of the shrinking serum which works for a brief time. They leave the island only to be marooned on another island during a storm. They find out that the island is going to be used for an H-Bomb test by the U.S military. Just as Konga returns to his full size he helps them operate a mirror to signal the island is inhabited. A U.S plane arrives and rescues Bob and Sandra but Konga is left behind as the H-Bomb blows up the island.
