Bubble Bobble's name becomes immediately apparent upon pressing the action button: a bubble shoots out of the dinosaur-lookin'-character's mouth.

Rainbow Islands: The Story of Bubble Bobble 2's name becomes apparent after maybe the first level.

"Oh yeah. This plays like Bubble Bobble."

I like the original Bubble Bobble a lot, but this one might actually be the better game. The way the rainbows function for trapping and attacking enemies while climbing up a level and avoiding obstacles works incredibly well. Real good stuff.
