Rainbow Islands Extra (レインボーアイランド エキストラ) is a strange update to Rainbow Islands: The Story of Bubble Bobble 2, released by Taito for arcades in 1988 before being ported to the Sega Mega Drive in 1990 exclusively in Japan.
Although it offers a port of the original Rainbow Islands, the default option is the "extra" mode, in which all the cute and colourful enemies found in the original game are replaced with enemies found in Taito's shoot-'em-up series, Darius. The music in extra mode has also been replaced with tunes from that game. The rules are otherwise the same as in the original - create rainbows to defeat enemies and reach the top of the screen.
The story for both modes is the same: Bubby's friends have been captured and turned into Bubble Dragons by Super Skull Monsta [sic], and Bubby needs to save them by destroying the Super Skull Monsta's minions with rainbows and collecting Little Diamonds to get Magical Mirrors needed to break the spell.
Rainbow Islands Extra was only released in Japan.
