Walkthrough
After defeating the Inner Sanctum Level (as well as Sector C), you will proceed to Heavenly Hall, the final stage in the Fortress of Shadows, Jambastion. The level begins with a number of hallways full of Enemies that you can easily defeat or befriend with the help of Kirby. Believe it or not, this path will immediately lead you to the throne room of Jambastion. Zan Partizanne, the next Boss and the third and final member of the Jambastion General Trio, sits atop the throne.
Upon seeing Kirby and his allies enter the throne room, Zan Partizanne will quickly zap over to them. She will quickly tell that she is the head general of Jambastion, as well as reveal the name of their leader, Hyness, before doing battle with you. As her name and title implies, she use Electricity Type Attacks in battle, so make sure to use plenty of Water Type Attacks (her greatest weakness) against her while yet still dodging her attacks. After defeating her, Zan will grab the Jamba Heart and then launch her spear in the core of the Fortress. Intent on burying Kirby in the rubble of the structure's collapse, this will cause the fortress to begin to self-destruct.
From here on out in this level, it is up to you to escape Jambastion. Kirby and his allies will quickly find a Friend Platform, using it to form a Friend Circle in order to begin their escape. You will remain in the Friend Circle for the next couple of areas, having to charge your way through Enemies and over pitfalls. After hitting the final wall, you will then need to form the Friend Bridge in order to unlock gates blocking the path ahead. Once this area has been completed, you will need to turn form Kirby and his allies into the Friend Star so you can fly straight out of the fortress. While flying on the Friend Star through the area with all the Buzzsaws, you can find the Rainbow Puzzle Piece on a sinking platform (having to grab it before it falls off the screen).
Once outside of the structure, you will need to defeat the ambush of Water Bubble Enemies with Kirby. After doing this, quickly fly through the last crumbling sections of Jambastion. Not only will this see Kirby finally escape this Fortress of Shadows, but it will also see you unlock the world known as Far-Flung Starlight Heroes.
