* AdaptationDisplacement: More people remember the show than the toy line that came with it.
* EarWorm: The theme song.
* FridgeBrilliance: Why, [[spoiler: when the Power of Ten]] is used on Simon and Snarf, do they not go away for good? Because, as revealed later, [[spoiler: Zirconia and Spinell's powers had been drained during their imprisonment]], so the spell wouldn't be at full strength.
* FridgeLogic: So the Ancients were around the same age as the girls when they fought Simon 3,000 years ago. [[spoiler: That means Zirconia and Spinell were either married as teens, or they were married after being transformed]].
* TearJerker: The montage of the girls coming back from the Old Trollz' Home wet and miserable in episode 9.
* TheyWastedAPerfectlyGoodPlot: There was a lot more the writers could've done with the story arc where the girls turned evil.
** On the website there is mention of Black Amber (implied to be very bad stuff) and how it contributed to how things turned out. It is never mentioned in the show.
*** Specifically, Simon was said to have unleashed Black Amber, ''almost destroying the planet''.
* UglyCute: Sandstone the ogre.
* UnfortunateImplications: Garnet, who is supposed to be black, [[spoiler: is evil]].
** Shale and Mica start out evil, too, but they reform.
** [[FridgeBrilliance Thinking about it more]], Garnet may have been like that as a counterpoint to Ruby. Doing everything a bit further than Ruby normally would, including appearance. Note her hair was darker, too.
* VisualEffectsOfAwesome: The effects used when casting spells.
