Blocks

 * Froglight
 * Dropped by small magma cubes when they are eaten by frogs.
 * Has three variants: pearlescent (purple), verdant (green), and ochre (yellow).

 * Mud.png Mud
 * Found in mangrove swamp biomes.
 * Can be created by using a water bottle, directly or through a dispenser, on dirt, coarse dirt and rooted dirt.
 * Can be converted into clay by placing mud above a block which has pointed dripstone underneath. The dripstone dries it out, producing a clay block.
 * This in turn enables renewable clay in (clay is already renewable in ).

 * Sculk Catalyst.png Sculk Catalyst
 * Generates in the deep dark biome.
 * Emits soul particles after a mob dies within 8 blocks, and grows sculk related blocks.
 * 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.
 * 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.
 * The experience will not be dropped in these cases.
 * The charge decays over time, faster the furthest away from the catalyst it moves.
 * If a charge decays more than 4 blocks away from the catalyst, it has a chance of creating either a sculk sensor (90%) or a sculk shrieker (10%).
 * If a charge decays more than 24 blocks away from the catalyst, it merely vanishes.
 * Drops only experience when broken without Silk Touch.
 * Emits a light level of 6.

Mobs

 * Allay.png
 * Voted to be in the update during Minecraft Live 2021.
 * Can find dropped blocks or items for a player, collecting the same items from the world as it holds in its hand.
 * Picks up dropped items in loaded chunks and can carry up to a stack at a time, and cannot duplicate items or take items out of chests. It drops its collected items when in range of a note block.


 * If holds an item it got from a player, it will follow that player.
 * It can be made to hold an item by interacting with the allay (pressing ).
 * The item can also be removed by interacting with the allay (pressing ) while with an empty hand.
 * Able to drop items at nearby note blocks, and stay close to a note block that has been played near them.
 * When playing a note block near them, that note block becomes their favorite one for 30 seconds, and they will attempt to drop off items at the note block rather than at the player.
 * If they have items in their inventory, they will attempt to give them to their owner.
 * Sometimes spawn in cages next to pillager outposts (similar to iron golem), and inside woodland mansions.
 * Has a delay for picking new items after delivering items.
 * Immune to damage from its owner while holding an item.
 * Have health points.


 * Comes in three variants: temperate, warm, and cold.

 * Frogs are faster in water than on land.
 * Prefer to jump to lily pad and big dripleaf.

 * Eats small slimes, dropping slime balls.
 * Eats small magma cubes, dropping froglights.
 * Can be tempted and bred using slimeballs.
 * Lay eggs on water after mating.
 * Grow from tadpoles.
 * Variants depend on the temperature of the biome it turns from a tadpole to a frog in.
 * Have health points.
 * Have health points.


 * Tadpole.png
 * Grows up into a frog 20 minutes after birth, which can be sped up using slimeballs.
 * Frog type depends on which temperature it grows in.
 * Can be held in a water bucket.
 * Jump around like fish when on land, and eventually die.
 * Panics on land and pathfinds to a nearby water source.
 * Are hunted down by axolotls.
 * Also panics if there are axolotls nearby.
 * Have health points.


 * Warden.png Warden
 * The first fully blind mob (bats have basic eyesight, both in-game and in the real world).
 * Because of this, it stumbles as it walks.
 * Has a sense of smell. It can detect and pathfind toward the general location of a player or mob through a "smelling" action.
 * Prioritizes smelling the player or mob that it is most suspicious of, rather than the one closest to it.
 * 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.
 * It does not attack other wardens.
 * When it detects a vibration, the growths on its head rattle and light up, similar to the sculk sensor.
 * Seems to follow the same rules as the sculk sensor when detecting vibrations.
 * If any projectile (e.g. egg, snowball, arrow) lands near it, the warden inspects the location where the projectile landed, due to the projectile creating significant vibrations. This feature can be used in order to cause a distraction.
 * Does not detect players that are sneaking.
 * Can detect players or mobs that have the Invisibility effect.
 * 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 aggravates it, causing it to pathfind toward the target to attack regardless of outside distractions.
 * Spawns in the deep dark biome, specifically when a player activates sculk shriekers three times.
 * It is the only mob that spawns in the deep dark biome.
 * "Emerges" from the ground when spawned by sculk shriekers.
 * Digs back into the ground when it doesn't sense any vibration after 60 seconds.
 * Like how name tags prevent despawning, name tags can also prevent wardens from being able to burrow back to the ground.
 * Wardens will not dig back when they're in water.
 * A mob designed to be extremely difficult, intended to be avoided and fled from.
 * Has health points and does  damage on Normal difficulty, bringing players wearing full netherite armor from full health to  health points. Wardens also disable shields when they hit the players with their fists, and are at least as fast as a walking player.
 * The warden doesn't qualify as a target for the advancement "Monster Hunter" and isn't needed to receive the advancement "Monsters Hunted" due to its role.
 * 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.
 * 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).
 * Wardens have long melee reach, being able to hit the player when on top of a four block pillar, thus making it capable of countering certain cheese tactics, such as pillaring.
 * Is immune to lava and knockback, and never slows down in water.

Non-mob entities

 * Oak Boat with Chest.png Boat with Chest
 * Similar to a minecart with chest, but with a boat instead of a minecart, so the player can take a journey on the water and carry things.
 * Can hold only one entity.
 * Crafted by combining a chest with any boat.
 * Comes in different wood plank variants, including the dark oak, jungle, and the newly added mangrove wood plank variant.
 * Opening its inventory or breaking it will make nearby adult piglins angry.

 * If the frame of reinforced deepslate generates with a chest in front, it will always contain one golden apple (a hint about how to open the secret door below).
 * Has different levels and open spaces, with several types of ruins and wall structures.
 * Some of these structures contain dark oak logs, planks, and fences; cyan, light blue, and blue wool and carpets; ladders; ice and its variants; note blocks; stone pressure plates; and iron trapdoors opened with levers.
 * Hidden underneath the frame of reinforced deepslate are several rooms containing redstone mechanisms that serve to introduce new players to their function.
 * There is a silenced sculk sensor that needs a signal strength of 8 to open a redstone door. Taking the golden carrot from the chest placed near the structure and eating it will reveal the entrance.
 * Each variant of the city center has a different redstone puzzle concealing the entrance, requiring slightly different strategies to solve.
 * The mechanisms are made with redstone dust, redstone torches, redstone repeaters, redstone comparators, redstone lamps, blocks of redstone, sticky pistons, a sculk sensor, a target, and a lectern.

 * section does not apply to a pack containing it, only to packs loaded before it.
