Bana Bana Ichi-gō: Rolypolys no Sekai Daibōken (バナバナ1号 ローリーポーリーズの世界大冒険, sometimes listed online as ローリーポーリーズの世界旅行, lit. Rolypolys' World Tour) is a 1997 point-and-click adventure game developed by OutSide Directors Company and published by Shinko Music Entertainment. It is the sequel to Rolypolys no Nanakorobi Yaoki, which released eight months prior.

The plot opens with "everyone's idol" Otane-chan being kidnapped by an evil tengu; she can only be freed by the Roly Polys gathering 6 keys scattered around the world. The gameplay centers around the Roly Polys flying to every continent of Earth in Banaten's spaceship, the Banabana Mk. 1, while learning about the geography and culture of various countries.

Lost Media Status

The full game is currently undumped. Several old listings exist on Japanese auction sites as well as one recent one in July 2020, and one image of the game in-box has surfaced. Aside from several small screenshots on the publisher's original site, no gameplay footage existed online until Rolypolys no Nanakorobi Yaoki was found, which contained a video trailer. This trailer was rendered in-engine, meaning its assets could be ripped.

The January 15, 1998 issue of Japanese magazine MacPeople came with a demo of the game as part of its included CD. This disc was uploaded to the internet on October 27, 2021. The demo only contains parts of the North American area of the game, and does not contain any data for the other areas.
