!!''HorrorsOfSpiderIsland'' contains the following tropes:

* LesYay: Two dancers insist they never dance in separate groups. Babs sneers she's had enough men. Of course, they all find the professor's assistants irresistable, so it could be a case of GirlOnGirlIsHot titilation.
* SpecialEffectsFailure:
** The plane crash is shown with stock footage, with the girls screaming in front of a black background. Because that's how airplanes were in the 1960s, I guess.
** In a decidedly more mundane case, the stripper gets slapped at some point. While they play the sound effects, it's not only incredibly obvious that no contact was made, but the stripper ''doesn't even physically react'' to being hit.
