Rainbow Islands/Islands 5 - 7

Island 5: Doh's Island
Reaching the fifth island is no small feat. However, as a reward, the game substitutes challenge for cameos. This is the first Taito theme island, and the theme is none other than Arkanoid. The island is named after the chief nemesis in Arkanoid II: Revenge of Doh, and all of the platforms are constructed out of Arkanoid bricks. All of the enemies are the shapes that appear throughout Arkanoid, and even the music and sound effects are replaced with the "ping" and "pong" noise created by the ball and paddle. Interestingly, the third round of the island, Round 19, is one of the shortest rounds in the game.

Boss: Doh
Doh appears at the top of the screen and remains stationary throughout the entire fight. Every so often, he fires a stream of spinning squares in your direction, which you can attack with your rainbows if you're fast enough. There are no platforms in the room. If you have one particular powerup, the book that gives you wings, this fight can be incredibly easy. if you don't have it, this fight can be incredibly hard. If you have the wings, all you need to do is fly up to his height, and attack and crush him with rainbows. If you don't have the wings, you'll have to generate platforms for yourself out of rainbows, and then attack him while you're high enough. Eventually, the rainbows will disappear, or you may jump on them and knock them down, and you'll have to repeat the process. If at all possible, make sure you have wings before you reach Doh. One surefire way to do this is to find the silver door on the fourth island and collect the giant book which gives you the wings permanently.
