This page documents a major update currently being worked on. 
Therefore, not all official feature names or items are mentioned.

The Wild Update is the name of an upcoming major themed update set to release in 2022 as Java Edition 1.19 and Bedrock Edition 1.19.0.[1] It adds the Deep Dark biome, along with the warden, sculk blocks and the Deep Dark Cities, and makes various other biomes more atmospheric and immersive. In addition, it also introduces several new mobs and biome variants.

Frog egg

  • Can't be obtaned in suvivle
  • Frog layes it when bread

  • Generates in the Deep Dark.
  • Made of sculk and a bone-like material.[6]
  • May be used in redstone.[7]
  • Spreads sculk blocks to wherever a nearby mob dies. The amount it spreads depends on the amount of experience the mob is meant to drop.[8]
    • This means that even if the mob doesn't drop experience as it wasn't killed by a player, the blocks would still spread based on the amount of experience it normally drops.
  • Sculk Catalyst Bloom.gif Blooms when activated.
  • Drops only experience when broken without Silk Touch.[4]
  • Emits light.
  • Emits soul particles after a mob dies and grows sculk.

Sculk Shrieker (pre-release).gif Sculk Shrieker
  • Generates in the Deep Dark.
  • Perhaps made of sculk and a bone-like material.
  • Has 2 soul-shaped patterns in the center.

Unknown frame block.png Frame Block[unofficial name]


Spawn Eggs
File:Bucket of Tadpole BE1.png Bucket of Tadpole[12]
  • Obtained by using a water bucket on a tadpole, similar to obtaining a bucket of fish or axolotls.
  • Can be used to transport tadpoles, also as with fish and axolotls.


AllayPixel.png Allay
  • Voted to be in the update during Minecraft Live 2021.
  • Can find dropped blocks or items for a player.
    • Picks up dropped items in loaded chunks and can carry up to a stack at a time,[13] and cannot duplicate items[14] or take items out of chests.[15] It drops its collected items when in range of a note block.
File:Frog BE1.gif Frog
  • Comes in three variants: default, tropical, and snowy.
    • The default variant is orange, the tropical variant is white, and the snowy variant is green.
  • Grows from a tadpole.
  • Variants depend on the temperature of the biome it turns from a tadpole to a frog in.

  • Eats fireflies.
  • Each variant is planned to have a unique use for players, currently unknown.
Firefly.gif Firefly

Tadpole.png Tadpole
  • Grows up into a frog.
  • Can be held in a water bucket.

Warden and rabbit

Warden.png Warden
  • Spawns in the Deep Dark biome, including within Ancient Cities.
  • The first fully blind mob (bats have basic eyesight, both in-game and in the real world).
    • Has a sense of smell. It can detect and pathfind towards the general location of a player or mob through a "smelling" action.[16]
      • Prioritizes smelling the player or mob that it is most suspicious of, rather than the one closest to it.[17]
    • Has a sense of vibration. When sensing movement, it pathfinds toward the source of the movement.
      • It follows and attacks players, mobs, and other entities that make vibrations.[note 1]
        • It does not attack other wardens.
      • Seems to follow the same rules as the sculk Sensor when detecting vibrations.
        • 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 significant movement. This feature can be used in order to cause a distraction.
      • Does not detect players that are sneaking.
    • Because of this, it can detect players or mobs that are invisible.[18]
  • Becomes more suspicious of a player or mob as it detects its location more through vibrations and/or smelling. When it suspects the target enough, it identifies its exact location, which causes it to aggravate and pathfind towards said target to attack regardless of outside distractions.[19]
  • Burns in direct daylight.[20]
  • It is the only mob that spawns in Deep Dark.[21]
  • A mob designed to be extremely difficult, intended to be avoided and fled from.[22]
    • Has a way to counter "cheesing" strategies like pillaring up to avoid attacks. The solution does not involve block breaking.[23][24]
    • Incredibly strong, doing 32♥ × 16 damage, bringing players wearing full netherite armor from full health to 7♥♥♥♥ health points.
    • Currently has 500♥ × 250 health points.[25]
    • At least as fast as the player's walking speed.
    • Seems to have knockback resistance.
  • The warden's chest has a glowing core that appears to brighten and dim in tandem with the Darkness effect.
    • The core creates a low throbbing or "heartbeat" sound as it pulses. The sound and animation speed up rapidly as the warden gets more suspicious of or closer to attacking a player or mob.[26]
  • 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).[note 2][27]
  • Can be summoned by sculk shriekers; a warden rises out of the ground nearby if too many are activated.

World generation

  • Completely overhauled.
  • Contains mangrove trees.
  • Contains mud.
  • Can spawn frogs.
  • Can spawn fireflies while nighttime.
Mangrove Swamp

  • Contains mud as ground.
Mangrove Trees
  • New type of tree.
  • Made of mangrove logs.
  • Generated roots composed of mangrove root blocks.
  • Has propagules hanging from leaves.
  • Found in swamps.
Deep Dark
  • New biome at the "deepest depths of the world".
  • Originally planned for 1.17, then moved to 1.18, and was then postponed to 1.19 due to increased scope.
  • May not contain any water or lava aquifers.[28]
  • May be the rarest cave biome.[29]
  • Tends to generate under continental/mountainous areas.[30]
  • Generates exclusively within the deepslate layer between Y=-1 and Y=-64.[31]
  • Contains Ancient Cities.
  • Wardens can spawn there through the activation of sculk shriekers.
  • Contains all sculk-related blocks.
  • With the exception of spawners, no mobs other than wardens can spawn there, similar to mushroom fields.[21]
Ancient City[32]
  • New structure that generates within the Deep Dark.

  • Made of deepslate and its variants, basalt blocks and its variants, planks, and wool.[33]
  • Contains soul sand, soul fire and soul lanterns.
  • Contains candles and skeleton skulls.
  • Contains chests with unique loot.[34]
    • The loot is intended to be items that cannot be found anywhere else, and that provide unique abilities and mechanics to players that weren't possible before and are not attainable by other methods.[35]
  • Contains the unknown frame block.
  • Has different levels and open spaces.
  • May have been built by an ancient civilization according to Brandon Pearce.[36]

Non-mob entities

An image of two variants of the Boat with Chest shown during Minecraft Live 2021

Oak Boat with Chest.png Boat with Chest
  • Similar to a minecart with chest but with a boat instead of a minecart.
  • Unlike the functionality of a minecart with chest, a player (but only one) can still ride in the boat when the chest is present.
  • Different wood variants.


  • Sculk Soul.gif Sculk Soul
    • Sculk Catalyst Bloom.gif Emitted by sculk catalysts when activated.
  • Shriek.png Shriek
    • Sculk shriek particles.png Emitted by sculk shriekers when activated.
Status effects
  • Darkness.png Darkness
    • A status effect triggered by the sculk shrieker block, causing the player's camera to dim in brightness, thus limiting vision.

Planned changes


  • More efficient way to regenerate clay by placing mud over a dripstone block with a stalactite dripstone growing under. The dripstone dries it out, producing a clay block[37].
Sculk Sensor
  • Now are able to activate sculk shriekers.
  • Now are able to communicate with warden.
  • Now are able to detect sneaking players who step on top of it.
  • Now generate in the Deep Dark biome.
  • Potentially planned to be able to detect a wool block but only when it is placed.[38]

World generation

  • Updating various overworld biomes, such as Birch Forests, to make them more diverse, unique and add more immersion to biomes in general.

Unconfirmed features


Status effects
  • Darkness might also be triggered by wardens given how the duration of the effect extended past the one imposed by the sculk shrieker in the Minecraft Live 2021 showcase, and as suggested by a tweet from kingbdogz.[39]


  • The warden was originally known as the "stalker" early during development. That iteration also had white flesh with holes in it, to the point where it was deemed too gory by the developers and had to be tuned down.[40]
    • Brandon Pearce also mentioned that this is one of various "wildly different" iterations that he's going to preview once the warden is released to the public.
  • This was the first update to add a 2-dimensional mob, the firefly.
  • This is the first update that features a losing vote candidate (biome, in this case), the Swamp biome update from MINECON Live 2019.
  • The tropical frog is based on the grey foam-nest tree frog.[41]
  • While this update introduces mud as a block, mud has existed in the franchise as a fluid in Minecraft Earth. The properties of mud in this update have not been stated.

  14. "Allays are not item duplicators, they pick up items nearby on the floor that are the same item it has been given.

  31. "Also, to clarify, the Deep Dark won't take up all of below y 0. Other biomes like Lush Caves and Dripstone Caves will be able to generate there too, it's just that Deep Dark can only be found below y 0. Grimstone is its natural stone ;)"@kingbdogz on Twitter, February 17, 2021

  39. "It is much darker in-game I would say, we had to brighten things up a lot for the Live showcase :) But I agree the name "Deep Dark" doesn't really fit the cities - but it does when the Darkness effect creeps in from the Sculk Shriekers and Wardens :D"@kingbdogz on Twitter, October 17, 2021

  1. The Warden does not attack non-mob entities but it does follow the vibrations that they make. It is unknown whether it does attack mobs (apart from the player) or not.
  2. Height of the warden is based from the image found on Twitter.
