From WiKirby, your independent source of Kirby knowledge.
Red Volcano is the sixth level of Kirby and the Rainbow Curse and the sixth section of Seventopia. It is a dark area with lots of flowing lava.
Each stage is unlocked in succession after clearing the previous one. Defeating The Claykken is necessary to move on to Purple Fortress. For more information about a particular stage, click on the link to the stage's page in the table.
Burning Secrets (6-1)
Lots of magma pools line the floors of this stage, making navigating the place a hazard. Lots of Hot Heads also reside here. Bastron is also encountered here.
Back to the Battleship (6-2)
This stage features the Kirby Rocket, and takes place mostly within the Bastron. A timed self-destruct sequence is done at the end.
Volcanic Panic (6-3)
This stage consists of several subterranean areas with rising magma pools.
The Claykken's Sea of Fire (6-Boss)
The Claykken is fought again here, but this time, the fight takes place over lava, and not in the water. The Claykken's attacks will temporarily break away the floor, but the fight is the same apart from these details.
