Moai Doo-Wop/Unused

Rhythm Heaven
Moai Doo-Wop consists of the following versions in Rhythm Heaven:

Early Ideas
Originally the game was about a king that would be sitting on the ground with his head in his hands, and a messenger standing behind him would hold the king's mouth and make him speak in turn. One day, this concept was suddenly replaced with the Moai.

Unused Content
An unused set of Moai voice clips include "su-an" for the held voice and "san" for the tapped voice. Additionally, unused voice clips of "konnichi", "sayona", and "gokuro" exist alongside, which seemed to be originally intended to connect to the tapped voice clips of the Moais.

Miscellaneous
Normally, each version with an ascociated prologue and epilogue would have the assets for them in subfolders within the versions they belong to. Moai Doo-Wop 2's prologue and epilogue are stored in monomane/ver2 however, which has the graphics for Remix 2 and Remix 9. It is possible they are simply attributed this way to save space, to avoid creating a duplicate of the normal graphics for Moai Doo-Wop 2.

Regional Differences
The prologue in Rhythm Tengoku Gold looks noticeably less polished compared to the international versions.
