Super Monkey Ball Banana Splitz, the upcoming PlayStation Vita based game from developer Amusement Vision and publisher SEGA, will include a stage that is based on the body of a well-known Japanese swimsuit model.

This adult map will be available only in Japan at the moment, and it will require gamers to find and then input a code that is hidden in a rather small number of copies of Super Monkey Ball Banana Splitz.

The two companies have not said whether they have plans to offer a similar bonus to those gamers who will play the game in North America and in Europe.

Super Monkey Ball Banana Splitz has gamers move their characters around by tilting the world itself rather than direct the game characters themselves.

The series was launched on the Nintendo GameCube first, and since then SEGA has ported them to almost all modern gaming consoles, including the 3DS handheld, the Wii home console and the iPad.
