THE BEAST FROM
Mysterious goings on prompt efforts to drain Foggybotom Lake. Talking dinosaurs who spit a potent venom gain hypnotic control of the workmen draining the lake, and it's up to Astroboy to put an end to it. (**This episode was produced by animators handpicked by Tezuka, but he was so disapponted with the end result that all prints in Japan were destroyed. Luckily for us, a print had already been shipped to the US and this english dub is all that survives of "The Lost Episode" of Astroboy.)
The talking dinos get the scientists under their hypnotic control to build a gigantic robot monster.
