- Celebrity Voice Actor: LeAnn Rimes as Kelly Deegan in Christmas Wishes.
- Franchise Killer: Fabulous Fashion Show was so badly reviewed across the board, with an overall 1.3/5 on Amazon with 18 reviews, compared to 4+ star averages for the others, that it all but killed the franchise. Marvelous Makeover rebounded to 3.3 stars, but the various changes that had been made to the series, such as moving to 22 minute stories, replacing most of the voices with canadian talent, and poor voice direction overall, were still generally poorly regarded. The show's final picture book release was seen a bit later in 2008, and afterwards, production on all media was discontinued entirely.
- No Export for You: There are no records of the direct-to-DVD shows being aired or released outside of North America, and the toys are pretty much this trope straight. The only thing that got exported are the books.
- The same can be said about the 2018 reboot. It only airs in the US, Canada, UK and Australia.
- Non-Singing Voice: From Fabulous Fashion Show onwards, Holly's talking and singing voices are helmed by two different VAs.
- The Other Darrin: Widely noted for most if not all of the key voices being replaced in Fabulous Fashion Show with Vancouver-based actors.
