It's one of my favorites of the "Astroboy" episodes, (and this episode is almost up there, in my opinion, with "Astro Boy" episodes: "Attack from Space" and "The Moon Monsters".) One of the other "Astroboy" episodes that features a "character crossover" from one of Tezuka's other series is "The Monster of Clarken". A character from another Tezuka Productions anime series, "Triton of the Sea" (a series not released in English) is featured at the beginning of the episode. The character's name is Pippy. (Although in the the American dubbed version, the character is known as Pepe. He's some kind of dolphin boy. I don't know the character's name from the Canadian dub.) The episode is also one of the better episodes.
I know it's elsewhere on this website, but I would really like to see Jayrath's notes on the making of this episode and who did what voices. It would probably be interesting to see his notes on the making of "The Time Machine" as well. Any way I'm recommending this episode to catch if you're are interested in seeing other Tezuka characters. Especially one not that well known in English!
