The Japanese version of the game contains downloadable maps featuring Japanese swimsuit model Yukie Kawamara that was only accessible via codes that were in specially marked boxes. In these maps, Kawamara's breasts are small bumps in the platforms that the player can roll on. This may have been deemed inappropriate for a kid-friendly game, which is why it hasn't been available in other countries for download since its release.
