- Cross-Dressing Voices: Snarf is voiced by Janyse Jaud.
- Dueling Shows: With Bratz, W.I.T.C.H., Winx Club, Mew Mew Power and Magical Doremi.
- Keep Circulating the Tapes: The only US DVD release this show ever got was in the form of 3 Compilation Movies, all of which have been out of print for over a decade. A complete series release was only in France.
- Name's the Same: Snarf from ThunderCats (1985) comes to mind.
- No Export for You: Some merchandise, like magazines and specific doll collections, were only released in Germany and the UK. A soundtrack CD was only released in Spain.
- What Could Have Been:
- As seen in this concept art, the main villain could've been a witch and the girls' mentor would have looked completely different. Kaboom was also slated to be part of the main cast.
- A very early promo image◊ had Onyx's hair be dark gray.
- There were plans to make a second season of the show, with the creators even having some titles already set up, such as "Coming to Your Town," "Magic of the Ten," "Trollz Gone Wild," "Topaz Makes the A-List," "Trollzbury Bake-Off," and "Clothes Make the Troll."
- An English soundtrack CD was planned to be released with 15 songs, and was promoted in the tie-in video game, but never made it to stores. The existing promo CD has only 11 songs.
- As part of the extras for "Best Friends for Life" and "The Magic of Five" a fourth compilation movie was advertised alongside "Hair Over Heels" called "You Glow Girls!" which would have featured the next three episodes of the series, "The Dating Game," "Mirror, Mirror," and, "Ruby's Rules of Partying." According to NCircle Entertainment, who distributed the Trollz DVDs, there was also a fifth compilation planned called "A Hair A-Faire," which would've featured the episodes "Forever Amber," "Not-So-Good Old Days," and "Simply Simon."
- Ruby casts the most spells in the series, while Onyx casts the least.
