 * Processing rubble


 * A technical block associated with archaeology.
 * At least comes in dirt and gravel variants.
 * Created upon using a brush on what appears to be normal dirt or gravel.
 * Has 16 layers.

Items

 * Warden Spawn Egg.png The Warden spawn egg is visually confirmed but not yet implemented.

Mobs





 * Spawns in the new deep dark biome.
 * The first fully blind mob (bats, despite relying almost exclusively on echolocation, still have basic eyesight).
 * When sensing movement, it moves toward the source of the movement.
 * It follows and attacks players, mobs, and other entities that make vibrations.
 * It does not attack other Wardens.
 * When attacked, it path finds toward the player.
 * Seems to follow the same rules as the sculk sensor when detecting noise.
 * When it detects a vibration, the growths on its head rattle and light up, similar to the sculk sensor.
 * If any projectile (e.g. egg, snowball, arrow) lands near the Warden, the mob inspects the location where the projectile landed, due to the projectile creating movement and noise. This feature can be used in order to cause a distraction.
 * Does not detect players that are sneaking.

 * The core creates a low throbbing sound as it pulses. The sound and animation seem to speed up rapidly when the warden notices a player.
 * Is about 3.5 blocks tall, making it one of the tallest mobs in the game, exceeding the iron golem and enderman in height and width (the same).


 * Goat
 * Spawns in mountain biomes.

Gameplay



 * The player can find items and blocks in gravel and dirt inside the dig site structure by using the brush.
