!!The TV series:
* CrowningMusicOfAwesome: Earle Hagen's theme and episode scores (as well as averting CaliforniaDoubling, the series eschewed tracking in music - [[Series/TheAndyGriffithShow like other]] [[Series/GomerPyleUSMC shows from ]] [[Series/TheDickVanDykeShow the same producers]], every episode had an original score, which was by no means common for 1960s TV).

!!The picture books:
* ItsShortSoItSucks: The original ''Spooky Mansion'' spurred a lot of complaints of this, as evidenced by Amazon reviews. The ''Deluxe'' version alleviated this heavily by giving it an overhaul described on the main page; given that most people seem to remember it a bit more fondly than the original, it probably worked.
* SurpriseDifficulty: Some people might be surprised that, in spite of the target audience being children, the riddles can be shockingly difficult and even stump many of the parents who were trying to solve the riddles with their kids, particularly the ones involving homonyms, as noted by WebOriginal/{{Brutalmoose}}.
* ViewerGenderConfusion: Skelly from ''Spooky Mansion'' is referred to with male pronouns on the CD case's description and on Scholastic's website, but is often mistaken for a girl due to his androgynous voice.
* VisualEffectsOfAwesome: Yes, in a children's book series. The grand majority of the books were written before Walter Wick moved to digital photography...which means that, yes, ''every single picture was completely real and done by hand, with zero photo editing.'' He even has a series of behind the scenes features on his web site detailing how he put together quite a few of the harder-to-explain pictures.
