Bowser in the Dark World (Shoshinkai)

Bowser in the Dark World (Shoshinkai) is an area in B3313.

Description
The area is unchanged from the vanilla Super Mario 64.

Origins
The area is taken directly from the vanilla Super Mario 64, along with the music. Bowser has a texture taken from the beta version of the same game (note the shell texture and blue eyes).

Plot significance
Bowser, one of the supposed main villains, appears in this area. However, him not saying anything besides a vague threat after being defeated makes his intentions ambiguous. Defeating him lets Mario/Luigi collect a Red Star, which causes a variety of events.
