Rolypolys no Sekai Ryokou (or Roly-Polys World Tour) is the sequel to Roly-Polys. It was released in December 1997 to Japan only, published by Shinko Music. Unlike its predecessor, there were no plans for international release.
It has since become lost media. Even less is known about this game than its predecessor, and there's no known pictures or footage of it aside from official sources and a video trailer of it (included in Roly-Polys).
