Tetsuwan Atom Odcinek 36: The Monster of Kuraken

Astro picks up a letter in a bottle in the sea and goes to find Peligro Island. But he is swallowed by an artificial sea snake and taken to an undersea mining base with other victims. Astro meets an old man and his daughter Lilly, who threw the bottle into the ocean, and rescues them both. The queen of the island, who believes that Astro is the bravest of men because he has got rid of the sea snake, is attracted to him and cuts off his head when he tries to leave the island. Astro sadly parts with Lilly who assumes he is dead.
