Blue Sky Palace
Blue Sky Palace is the fourth level of Kirby and the Rainbow Curse and the fourth section of Seventopia. It is characterized by cloudscapes and regal structures.
Rainbow Across the Skies (4-1)
This first stage takes place in open air, with virtually no floor anywhere to land. Kirby will have to rely on the Rainbow Rope and currents of wind to stay afloat. Balloons carry enemies and items about the place.
The Wild Red Yonder (4-2)
This stage takes place in a cloud fortress. Bastron is first seen here.
Kirby Rocket's Big Blastoff (4-3)
As the title implies, this is where Kirby Rocket makes his debut. Rocket Kirby moves very quickly through the stage, which is useful, as the last section is set to self-destruct.
Sky-High Whispy Woods (4-Boss)
Whispy Woods is engaged again here, though the fight is a bit different. This time, Whispy is encased in metal, which makes him immune to anything except a Star Dash. Apart from that, the strategy is the same.
