Jonny Quest (1964) - 1x14 - Dragons of Ashida- Followmy.tv

Dr. Quest visits Dr. Ashida on his private island (named, what else, Ashida). Dr. Ashida boasts of how he has created giant, ferocious lizards from a much smaller species.

The team escapes, barely, wondering what to do about Dr. Ashida. It turns out they need not worry: Dr. Ashida has punished his henchman once too often...
