Walkthrough
After defeating Meta Knight, Kirby and Friends will head straight to the newly landed Jambastion, the Foretress of Shadows. Something is definitely going on within the structure, and it is up to Kirby and others to find out what it is and put an end to it. They will enter this world of sorts with Gatehouse Road, a creepy path that is destroyed in a number of areas. It is here you will also face more Bosses.
Outside of the normal basic Enemies you find in all levels, almost all of the best content of Gatehouse Road begins in its fourth area. It is here that you will find the stage's Rainbow Puzzle Piece. In order to find and obtain it, simply destroy all of the rocks found on the path in this fourth area. It's just that simple.
At The End of the level, you will face not one, but two real Bosses: Pon and Con. These two are the guardians of the gate, and they must be defeated before you can pass. Pon and Con will constantly charge at Kirby and his allies, so plan on dodging quite a bit in this battle. Like any Mini Boss or Boss, you will have to keep attacking these two as you avoid their attacks. Kirby can defeat them by inhaling their children, before spitting them back at the two Bosses.
Once Pon and Con have been defeated, you can actually make Friends with the two Bosses. They will then open the gate for Kirby and allow him to pass, allowing you to proceed to the next level.
