- Dawson Casting:

- In the Media Blasters English version, Arusu and Sheila were played by the 45-years-old Julie Maddalena and the 35-years-old Cindy Robinson.
- Cross-Dressing Voices: The Media Blasters English version has Lennon voiced by Brianne Siddall.
- Directed by Cast Member: Tony Oliver (The Ecoo Fairies, Jidan & Googoo) directed the English dub of both the series and OVA.
- He Also Did: Sachiko Kojima, the Japanese voice actor of Arusu, voices Pearl in Steven Universe.
- Late Export for You: The series ran in Japan from April 19, 2004 to March 4, 2005, with a 6-episode OVA spin-off titled Tweeny Witches: The Adventures released on 22 November, 2007. Both the series and OVA were released by Media Blasters in North America in 2008 and 2009 respectively.
- Market-Based Title: Don't blame Media Blasters for the unusual English title; the Japanese producers came up with it themselves. To be fair, it is somewhat more fitting of the actual series than the Japanese title, which translates to "Magical Girl Squad Arusu".
