* EarWorm: Many of the songs are forever etched into the minds of those who grew up with the series.
* HilariousInHindsight:
** The songs "[[http://www.youtube.com/watch?v=l-Gq17O-HRc Magic, Magic E]]" and "[[http://www.youtube.com/watch?v=zdzC_VhjYBs Drop That E]]" were completely innocent when they were first shown, but schools continued to show them to kids long after "E" developed its other meaning.
** "The Boy From Space" includes a character who bears more than a passing resemblance to the Tall Man from the ''Film/{{Phantasm}}'' series.
* NightmareFuel: Charn, the BigBad of ''Through The Dragon's Eye''.
** The Thin Man, from "The Boy from Space". Something about the way he just lurches around awkwardly, and that stare...and as previously mentioned, he bears a striking resemblance to the Tall Man from ''Film/{{Phantasm}}''.
