According to its designer, the development of the "Magical Kids Doropie" project took approximately 10 months to finish. The title was originally planned to be a licensed game based on the 1986 anime "The Wonderful Wizard of Oz". However, the anime's copyrights for Japan were held by TV Tokyo, so the designers were unable to use it. They decided to develop their own basic design, which ultimately became Doropie. The name Doropie is a transliteration (or gairaigo) of Dorothy of "The Wonderful Wizard of Oz" anime. The rest of the Doropie design did not contain any other references to Dorothy or Oz.
