Like Bubble Bobble before it, the game has multiple endings. To get the "True and Happy" ending you must find and complete the three secret islands (although most consumer versions of the game completely lack the secret islands). These islands are not visible until all 7 big diamonds are collected. To get a big diamond, the player must collect seven different-coloured small diamonds on the island and finish the round.
How to Play
Kill enemies by hitting them with rainbows or by crushing rainbows on their head. There are seven levels each with four rounds. Holding down the jump button will allow you to jump onto rainbows without crushing them.
