Walkthrough
After activating the Hidden Switch in the level of Star Lavadom, you will unlock the extra stage of Extra Planet Y. Throughout this level, you will be faced with a number of crushing hazards and various enemy ambushes. Like all levels, Extra Planet Y also features its own Rainbow Puzzle Piece for the finding. This stage even has a Mini Boss Battle against not one, but two of the Mini Bosses.
The level begins with a Switch that you must press, causing the floors and wall to shift rapidly. You will obviously need to keep up in order to have Kirby crushed. The second area is just like the first, except that it is through a different grid and has even more different patterns.
From there, you will need to make your way through a volcanic area as the ceiling slowly begins to close in on Kirby. It is here that you will need to pick up a Key along the path, carrying it safely to The End of the area in order to access the round trip door. Once inside, this door will lead to an Icicle Lance Challenge, and conquering it will see you obtain the next Rainbow Puzzle Piece.
In the final area of this stage, you will first have to deal with more enemy ambushes during meteor storms, just like the previous level. Once they have been taken care of, you will face the next Mini Bosses of Bugzzy and Vividria. Of course, their power continues to be increased within this fourth world of the game. Once you have defeating both of the Mini Bosses, you will merely have to avoid being crushed by the platform that will take you to The End of the level.
