Rainbow Islands Evolution is a game in the Bubble Bobble series for the PSP system. It is also known as New Rainbow Island: Hurdy Gurdy Daibōken!! (NEWニューレインボーアイランド ハーディガーディ大冒険!!, Nyū Reinbō Airando Hādi Gādi Daibōken!!) in Japan. It is an enhanced remake of the arcade game Rainbow Islands.

Bub and Bob, the two main characters in the series, are against an evil recording company that seeks to pollute the Rainbow Islands' atmosphere by creating constant musical noise, therefore wilting the flora and mutating the fauna. Bub and Bob use a hurdy-gurdy as a weapon to create the rainbows.

The game follows the same vertical-scrolling system from the original, but it expands to a third dimension as there are platforms in the background which become accessible through the course of the game.
