Plot Summary

Sitting alone at the beach one day, watching wave after wave break on the lonely sand, Astro Boy spots a mysterious bottle being washed ashore. The bottle proves to contain a note calling for help and rescue from a dreaded, but unknown, uncharted island called Sea Serpent Isle. The note is signed “Princess Papaya Petal.” Doctor Elefun knows nothing of Sea Serpent Isle other than many ocean liners in recent days have disappeared after reporting sightings of giant sea serpents. And these disappearances always occur in the same region, although there are no islands in that particular part of the ocean. Astro Boy’s investigations over and under the water reveal that there is indeed an island, not a natural one, but a man-made base that, like a submarine, can appear or disappear at will. Giant tentacles shaped like sea serpents attach to ships at sea, pirate the ships' cargo, then force the passengers to work at hard labor on the “island.” Astro Boy himself is captured. Taken to the base “hospital,” he meets Princess Papaya Petal...and devises a plan for escape. Prisoners are sent floating to safety within giant laboratory bottles while Astro Boy himself sets out to stop the men and machines behind the threat of “Sea Serpent Isle.
