 * Powder Snow.png Powder Snow


 * Similar to snow, but entities fall through it, similar to cobwebs, but faster.
 * This is how regular snow layer blocks worked in old versions of Minecraft, but it was changed because it created accidental booby traps when lava ponds generated at the right height to cut out the ground but not the snow.

 * Sculk Something.png


 * Generates in the deep dark caves.
 * Made of sculk and a bone-like material.
 * While this block's use and function is currently unknown, it is speculated that this block is the source of the other sculk blocks due to the block always appearing in the middle of each sculk growth. This could possibly mean that the other sculk blocks grow out from the sculk chute, however this is just speculation.


 * Sculk Growth.png

Items

 * Axolotl Bucket JE1.png
 * Obtained by using a water bucket on an axolotl, similar to fish.
 * Had no name in the Minecraft Live 2020 demo, showing its translation string.


 * Brush.png

 * Sweeps debris off archaeological items one layer at a time. If interrupted, the block it was being used on simply disappears, and does not yield custom block heights.
 * Also comes in a blue-green variant: Brush 2.png

 * Can be tamed by capturing it in a bucket.
 * Come in different colors (leucistic, yellow, green, brown, and purple/pink).
 * Plays dead when damaged, receiving Regeneration. Appears to turn invisible or teleport after this, although the latter may be just a bug or a glitch.
 * This regeneration ability is likely based on how real axolotls can regrow lost limbs.
 * Attacks drowned, guardians, elder guardians and fish. Damage is yet to be confirmed, but will be balanced.
 * Sometimes can give Regeneration to the player who tamed it.


 * Glow Squid.png


 * Originates from Minecraft Earth.
 * Glows in the same way that magma cube cores, vexes, blazes and the eyes of spiders, drowned, and endermen do.
 * Spawns in deep ocean biome.
 * Likely to spawn in flooded caves as well.
 * Was decided on based on a mob vote between it, the Moobloom from Minecraft Earth, and the Iceologer from the Minecraft Dungeons DLC Creeping Winter. Failing mobs are less likely to be added but still have a chance to be implemented in the future.


 * Warden.png




 * Spawns in the new deep dark biome.
 * The first blind mob.
 * When sensing movement, it moves toward the source of the movement.
 * 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, like a snowball or an arrow, is thrown and lands near the Warden, it causes the mob to head to the location of where the projectile landed, due to the projectile creating movement and noise. This tactic can be used in order to cause a distraction.
 * Does not detect players that are sneaking.
 * Can detect players that are invisible.
 * Can detect players using elytra.
 * When aggravated for long enough, the warden follows the player continuously, regardless of any other distractions.
 * Attacks any mob that makes vibrations, not just players.
 * Can detect ringing bells.
 * Can detect players eating.
 * Incredibly strong, doing damage, bringing players wearing full netherite armor from full health to  health points.
 * Has at least health points, although it is estimated to have up to, putting it on par with the iron golem and ravager.
 * A mob designed to be extremely difficult, and fled from.
 * Has a way to counter the strategy of building up 3 blocks to avoid attacks.
 * At least as fast as the player's walking speed.
 * Seems to use the energy of vibrations to move faster.
 * Seems to have knockback resistance.
 * The warden's chest has a glowing core that appears to brighten and dim in tandem with the ambient lighting of the deep dark cave biome.
 * 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 3.2 blocks tall, making it one of the tallest mobs in the game, exceeding the iron golem and enderman in height and width (the same).

World generation

 * Archaeological excavation


 * A new semi-underground structure where archeological items and ceramic shards can be found.


 * biome


 * New biome at the "deepest depths of the world".
 * Wardens can spawn here.
 * May contain candles.
 * Contains sculk blocks, and the new Skulk Sensor Blocks, a new block that responds to vibrations.
 * Contains a new Unnamed Block.

 * Seems to be possibly a large tunnel-like cave.
 * Not much is known about this biome yet, but it was confirmed on Twitter by Henrik Kniberg.


 * Possibly contain "catacomb" style branching cave sections.




 * More extreme and smooth terrain.
 * Likely change to the generation of alternate stone types, to make them appear in larger but less numerous deposits.
 * Possibly seen in a screenshot tweeted by Henrik Kniberg, in which diorite appears to generate in a long and flat horizontal strip, rather than a small unevenly shaped patch.

Gameplay



 * The player can find items and blocks in gravel and dirt inside the dig site structure by using the brush.
 * Possible items shown in the preview footage include:
 * Ceramic shards of varying color that depict different images.
 * Diamond blocks and emerald blocks are probably not a part of this list and serve as a placeholder.




 * While in the deep dark cave biome, the ambient lighting occasionally dims temporarily, limiting the player's visibility. This serves as a warning that the warden is nearby.




 * An action can cause vibrations in the air, which can be picked up by sculk sensors and wardens
 * Can be caused by walking (but bats?), block placing, block breaking, doors or trapdoors opening, chests of any kind opening, pistons activating, and projectiles such as snowballs, eggs, or arrows landing. This does not include ambient weather such as rain or snow

Blocks

 * Wool


 * Used to block a sculk sensor's ability to sense vibrations.



World generation

 * Caves


 * Complete generation overhaul.
 * Many variations on cave types and cave design.
 * Biomes within caves introduced.

 * Other Stones


 * Diorite and what appears to be tuff spawn in layers of rock in straight lines instead of splotches.

Structures

 * Underground Cabin


 * Seen in the Deep Dark biome during the Minecraft Live 2020 stream.
 * Consists of a chamber with a cobblestone floor and stripped log support beams, containing 3 barrels, a blast furnace, and a large chest, with cobwebs and candles in and around it.
 * May possibly not be a generated structure, but instead a construction built for the purpose of the Warden showcase.

General
Height Limit


 * May be increased.

Trivia

 * It was confirmed to be a placeholder for new, biome-specific light sources.
 * The name "Sculk sensor" is derived from the word "skulk", meaning "keep out of sight, typically with a sinister or cowardly motive".
