Crash Clouds is the third stage of Revenge of the King in Kirby Super Star Ultra. It is a harder version of Bubbly Clouds from Spring Breeze, and features a similar topography, the same theme music, a similar opening cutscene, and a similar boss, in the form of Kracko's Revenge. Apart from the different coloration, a few differences include tougher and different enemies, and a generally expanded topography.
In the opening cutscene, Kirby sneezes, causing a few tiny stars to fall. He sneezes again, but unlike the original, where Kirby is knocked off by stars, a sleeping Galbel falls onto him. The Galbel lets out a small sneeze while it is sleeping. Even though it appears in the opening cutscene, Galbel does not appear in the stage itself.
From there, the cloud fields become more open, as Kirby must progress to the right.
Kirby stumbles onto more solid ground, but more foes await him here.
Back on the cloud palace walls, Kirby will have to bust through some soldiers and their big wall of Star Blocks before proceeding.
In the last area, Kirby will need to ascend past several disconnected islets. The door at the top leads to the boss encounter (details in section below).
Enemies, mid-bosses, and boss
Boss: Kracko's Revenge
Kracko's Revenge ambushes Kirby at the top of the tower. Its attack patterns are largely the same as Kracko's, but it has enhanced Vitality and speed. Kracko has a new attack where he moves at the center of the screen and shoots lightning bolts in all 8 directions.
