We should also include the pac files for the Subspace enemies, which i don't know which ones are needed, which is why I say we should add them.

I know that
adventure_common.arc, in the adventure folder inside the stage folder, holds the adventure items like the key and life stock, and the Primid with all of it's animations (It's almost like a full playable character, but is missing animations like different speeds for wlaking and the win/lose poses and that stuff.), it's weapons and eyes. Because of how complete the Primid is towards a playable character, it's almost like making the playable Giga Bowser, there is really just the item aniamtions that would need to be made, if you use all of it's strange attacks.
