Within the game's data is code for Kirby to change his skin color upon acquiring certain copy abilities, a trait which was previously seen in past Kirby games before being completely phased out from Kirby's Return to Dream Land onward. This feature appears to have been abandoned relatively early into development, as it is nonfunctional when in the world map and when using Mouthful Mode (both of which use different parameters from typical in-level gameplay). Additionally, the game contains code for displaying a yellow-skinned Kirby. Parameter names associated with this skin indicate that it was intended for a two-player mode, similarly to various other Kirby titles.
