Walkthrough
After completing Planet Misteen (and even Extra Planet A), you will unlock the next level of Mareen Moon. This stage is almost identical to that of Planet Misteen - being the planet's moon - and it's a relatively short level. Outside of being able to find the next Rainbow Puzzle Piece, this stage features a Boss Battle against two new Bosses.
The level begins on a bridge above another pool of Water, with the path eventually leading you back into the water. The path will ultimately lead Kirby back out of the water, giving you a chance to customize his party before heading straight into the Boss Battle up ahead. Along this main path, you will be able to find a round trip door above some underwater Gordos that will lead to another room. Within this room, use Kirby to Bomb all the blocks on the way up the strong current, as this will unlock a cache containing the Rainbow Puzzle Piece for this stage.
The main path of the level will lead you straight to the Boss Battle against both Goldon and Silvox. Even though you haven't faced them before, this fight will be extremely similar to the one you had with Pon and Con so long ago. However, as the battle progresses further, the battlefield will actually change in both size and appearance, giving Goldon and Silvox an extra advantage. Defeat Goldon and Silvox to clear this level.
