To apply a new Menu Body, follow these instructions:

1). Navigate to \BoringManRewrite\mods\boringMadness2.0v\Menu Bodies and open the folder with the name of the character you would like to use, then copy the spr_menu_stickman.png file.

2). Go back into the mod's main folder and paste it. Be sure to hit replace.

The next time you load the game, your Menu Grunt will have the new appearance.

Note:
If you ever wish to revert back to the default style, go into the Default folder and repeat the process.
