Mario Paint | Burning, Churning Power Plant - Kirby and the Forgotten Land

Near the end of the game, you traverse a factory of sorts because it wouldn't be a Kirby game without some sort of factory to investigate or whatever. This level also hides one of the 3 HAL rooms in the game and how you find is that you need to reach a certain part of the level before the next check point, then go all the way back to the start of the level. Also a lot of people pointed out that this theme is more of a spiritual successor to the factory theme from Kirby 64, so that's what I went with when making this.
