A unique casting change occurred and instead of an official departure removing the character Jo from the cast, when Shannon Chandler left the series, her character remained. Halfway through Season 1, Wolfgang, while playing with a magic book, accidentally cast a spell that caused Jo to change in appearance. Brittany Konarzewski took over Chandler's role in the guise of actually being the original Jo with a new look and voice. To counteract this, Flabber used his magic to make her look and sound the way she always had, but it didn't work on anyone who actually watched the spell being cast. So the viewers, Flabber, Drew, Roland, & Jo herself could still see Jo in her new appearance, but the Hilhurst monsters, as well as their family & friends, saw her as she looked before.
