Nintendo Treehouse did not expect the WarioWare series to receive more installments after WarioWare: Touched!. They also did not believe that the character Ashley would not make any further appearances in the Wario franchise as a whole, so they cast a random localization employee named Christine Peyser to play Ashley in the English version of the game instead of a professional voice actress. This would become problematic as the WarioWare series proved its longevity, with Peyser being forced to abandon projects to record Ashley's lines. Ashley, alongside the entire WarioWare cast sans Wario, would eventually be recast in WarioWare Gold.
