Castle Grounds

Castle Grounds is an area in B3313.

Description
The area looks much like the one with the same name in the vanilla game, with some changes. There is now a courtyard area at the back of the castle, with a Toad statue, a cave entrance. and a castle back door. Additionally, the moat has an extra hole, and no underwater door, but there's one on the surface. A strange clock symbol replaces Peach's portrait on the castle's front wall. Pressing the L button here will allow you to switch between Mario and Luigi at will.

Nighttime Castle Grounds
Starting the game at nighttime (8:00 PM to 4:59 AM) will start you here instead. Exits that normally lead to Castle Grounds also have a random chance of leading here. This version of the map shares some differences with its daytime counterpart:


 * Water is drained from the moat
 * Pressing L no longer switches characters
 * The fake window containing a wing cap block is removed, as well as the door behind the clock symbol.
 * The back entrance of the castle is missing a door
 * Going out of bounds by the lake will now kill the player, respawning them in the Plexal Lobby

Origins
The front area comes from the Shoshinkai beta version of Super Mario 64. The Toad statue in the back area can be seen in some of Greenio's videos, but is otherwise an original creation, with some textures from the beta version of the game.

There is no music playing in this area, as per usual.

Leading here

 * Beta Lobby B: Enter the double door at the back.
 * Beta Lobby C: Enter the double door at the back.
 * Beta Lobby D: Enter the double door at the back.
 * Crescent Castle: In the art hallway's right side room, enter the hole in front of the cloud painting.
 * Plexal Basement: In the main room's front side, swim down the tunnel in the floor and then through the hole.
 * The Void: Jump into the large hole.
 * Tiny-Huge Island (beta): Dying here by going out of bounds brings the player to a slightly altered version of the Castle Grounds, in a different area (Overworld), with another skybox, certain objects misplaced and only the front door warp working.

The game spawns the player to the Castle Grounds by default after selecting a file.

Trivia

 * In v0.4, the back of the castle had a double door on one of the walls which led to the Clock Hall. Additionally, the back door led to the Dark Lobby instead.
 * Although not visible due to the game engine's limitations, there are two Yoshis in the area at the same time.
