Rainbow Islands
Game Boy Color · 2001
About this game
The sequel to Bubble Bobble , Rainbow Islands sees Bub and Bob who were turned into human form at the end of its predecessor, attempting to rescue the inhabitants of the titular Rainbow Islands from the evil Boss of Shadows.
Instead of bubbles, Bub and Bob now have the power to cast rainbows, that can be used to directly destroy baddies or trap them underneath.

Killing the baddies will leave an item that can be picked up for score.
By trapping beasts under your rainbows and jumping on them to break them, you can collect seven different colored diamonds or power-ups for extra speed and rainbows.
There are ten islands in total, seven regular ones and three hidden, with increased complexity and difficulty.
The boys must travel vertically four levels on each island, using rainbows as platforms to ascend.
Each island ends with a big, bad boss that must be defeated to continue.
Like in the predecessor there is more than one ending, depending on how the game was played.
The three hidden islands will not appear unless seven colored diamonds are collected on each level of the first seven islands, and the order might even matter!
About Game Boy Color
The Game Boy Color (1998) added a color screen to the original Game Boy formula while remaining backwards compatible with the entire existing cartridge library. Its colorful, semi-transparent cartridge shells make it a visually distinct platform for shelf collectors, and several late-cycle exclusives — released just before the Game Boy Advance took over — are notably harder to find complete today.
Gamevaro tracks Rainbow Islands for Game Boy Color with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Rainbow Islands to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GBC release dates back to 2001.
