Rainbow Islands GENESIS

Rainbow Islands: The Story of Bubble Bobble 2 is Taito's 1987 arcade sequel to Bubble Bobble, later released on the Mega Drive. Bubby and Bobby, now in human form, must climb a chain of islands to rescue their inhabitants.

Instead of blowing bubbles, the heroes cast rainbows. They can be used as weapons, as bridges, or as stairs to climb toward the top of each vertical level before the water rises. Collecting the seven colored diamonds on each island unlocks the true ending, so a lot of secrets are hidden throughout the game.
