He only changes up the palettes

Turns into Dark Doise instead of Super Noise (once again, palettes.)

The Doise uses Boulders instead of Bombs, the boulders only function like the brick ball from noises pig city playthrough

In the noise fight, instead of noisette coming from off screen, peppino mach runs into the arena and grabs noise, once you enter the fight again, you'd find a bruised noise angered by his defeat (floor 4 hub noise).

Basically (barely) anything is original so i barely have to code stuff, just parent objects, reskins, and palettes
