- According to Wikipedia's entry for the cartoon series, Season 2 was entirely a rerun of Season 1.
- For the three episode segments listed as "Unknown", after culling a number of sources, it seems that these are the missing titles- "Footprints Under the Window", "The Phantom Freighter" and "A Figure in Hiding". However, it is not known exactly where they aired and how they were paired up. The first issue of the Gold Key comic book series based on the cartoon adapts "Footprints Under the Window" as the first story, so it seems likely this one may be the first episode.
