Bowser in the Bully Battlefield

Bowser in the Bully Battlefield is an area in B3313.

Description
The area is a large, flat area with grey ground and walls, with some patches of lava. This area houses one of the 4 Bowser fights in the game. There are bullies all around, making the fight quite annoying to deal with. However, one strategy is to let Bowser run towards the player while they're near a bomb, so that it is much easier to throw him into it.

Origins
The area seems to be an original creation, with textures originating from the vanilla Super Mario 64 as well as presumably some beta elements.

The music is a remix of the final boss theme from the Super Mario World OST.

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 his key, which lets them access more areas (there are 3 keys collectable in the hack, however which of them opens exactly which key doors is currently unknown).

Trivia

 * Despite the area being located in the second Bowser level, Bowser doesn't use the attacks that he gains in that fight. This is likely because they wouldn't function properly.
