Mob

A mob is an AI-driven game entity resembling a living creature. The term "mob" is short for "mobile entity". All mobs can be attacked and hurt (from falling, attacked by a player or another mob, falling into the void, hit by an arrow, etc), and have some form of voluntary movement. Different types of mobs often have unique AI and loot.

Spawning
Mobs spawn in various ways. Most mobs spawn naturally, depending on the light level, biome, and their surroundings. For example, most animals are found in bright areas on the surface, whilst hostile monsters are commonly found in the dark (whether if it’s a cave, dungeon, mansion or at night). Animals usually spawn upon chunk generation, while hostile monsters spawn and despawn in certain radii around the player. Some mobs including passive and neutral animals, and even hoglins have the ability to be bred by the player, creating offspring. Villagers also breed randomly depending on the time of day and the number of beds (though they can’t be directly bred by the player). Most mobs never spawn on transparent blocks, in water (except fish, dolphins, turtles, and other aquatic creatures), in lava (except for striders), on bedrock, or on blocks less than a full block tall (such as slabs placed on the bottom half). The exception is monster spawners, from which monsters can spawn naturally on any block including air.

Some mobs (like the snow golem and the wither) require that the player "construct" them before being able to spawn. The iron golem can spawn naturally and can also be constructed. The ender dragon can be respawned with four end crystals.

Players can also spawn mobs easily by using a spawn eggs in Creative mode, or the command.

Despawning
Many mobs despawn (cease to exist) after a certain amount of time if far enough from the player. $$, most passive mobs do not despawn, while most monsters do. $$, almost all mobs despawn.

Behavior
Mobs are affected by the environment in the same ways as the player: they are subject to physics, and they can be hurt by the same things that harm the player (catching on fire, falling, drowning, attacked by weapons, /kill command, etc.). Some mobs may be resistant or immune to certain hazards, such as some Nether mobs, which are immune to fire. All aquatic mobs except dolphins are immune to drowning. Mobs can ride minecarts and other mobs can climb up ladders. When mobs are killed, they turn to dust and drop items that may be useful resources. Each type of mob in Minecraft has a certain AI (artificial intelligence) system with different behaviors and mechanics. Mobs ordinarily wander around at random if there is a player nearby and usually avoid walking off blocks high enough to cause falling damage. Many mobs have an advanced path-finding system that allows them to navigate through obstacles to get to a desired object or destination. Passive mobs flee in random directions after being hurt, while hostile mobs face and chase/attack the player as soon as the player comes close. Neutral mobs remain neutral until a player or mob provokes it (usually by attacking), at which point the neutral mob becomes hostile toward and attack the entity that hit it. Most mobs are aware of players within 16 blocks of them, but some can see farther. Conversely, most mobs can be heard by players up to 16 blocks (spherical) away. Mobs in creative mode are harmless.

Most mobs cannot see through most solid blocks, including semi-transparent blocks such as ice, glass, tall grass, or glass panes. Mobs do not attempt to walk on rail tracks unless pushed onto the rails by other mobs.

List of mobs
Mobs are listed and classified by their nature from the player's perspective. For more details on a particular mob, click on them to view their individual page.

Passive mobs
Passive mobs are harmless mobs (except for pufferfish) that do not attempt to attack the player, even when provoked or attacked. Most of them can be bred or tamed.

Neutral mobs
Neutral mobs are sometimes passive and sometimes hostile toward the player. All of these mobs (except goats) are provoked when the player attacks it first. Some mobs may also be naturally hostile with provocation, and some mobs also have some additional way to be provoked.

Hostile mobs
Hostile mobs are dangerous, aggressive mobs that always attack the player within their respective detection ranges. Some passive mobs such as chickens and skeleton horses can be hostile if ridden by a hostile mob on rare occasions.

Boss mobs
Boss mobs are special hostile mobs that are distinctly more dangerous and tougher than other mobs. They do not spawn randomly, and are confronted intentionally. All of them also have a boss bar featuring their name and health. Boss mobs provide unique challenges but also equivalent rewards.

Unused mobs
Only contains a few mobs that never spawn naturally in-game as they can only be summoned with the command though the zombie horse can be spawned in with a spawn egg.

Removed mobs
Removed mobs no longer exist in current versions of the game.

Joke mobs
Mobs that were added as a joke for April Fools' Day $$.

Unimplemented mobs
Mobs that were announced by Mojang as confirmed, mentioned or potential future additions, but either got replaced by other mobs or scrapped.

These mobs either:
 * Were said to not be added in a future update (the mobs that lost the MINECON Earth 2017 mob vote)
 * Were said to have a possibility of being added in a future update (the mobs that that lost the Minecraft Live 2020 and Minecraft Live 2021 mob votes, and the Firefly)
 * Are not known to be under consideration for a future update (the Red Dragon and the mobs that lost the China Edition mob vote)

Mob vote
In 2016, Jeb held an informal poll on Twitter in which the public voted on adding the llama to Minecraft over the alpaca. In the five annual Minecraft events MINECON Earth 2017, MINECON Earth 2018, MINECON Live 2019, Minecraft Live 2020 and Minecraft Live 2021, the public also voted on a mob to be added to Minecraft. In the first vote, the winner was the phantom (then known as "Mob B" or "The Monster of the Night Skies"). In the second, the winner was the taiga biome and the fox. In the third, the winner was the mountain biome and the goat. In the fourth, the winner was the glow squid. In the fifth, the winner was the allay. Before the second vote, the China Edition also had a mob vote, the winner of which was the panda.

Classification
Most of the mobs are divided into different types, such as the animals or the monsters, but some creatures are assigned to a more detailed group. There are a total of four mob classifications that have different effects than other mobs.

Weaknesses and immunities
Some mobs are weak or immune to certain kinds of damage. Sea creatures, such as turtles, take more damage from tridents that are enchanted with Impaling. Skeletons and their variants are immune to drowning. All undead mobs are healed by potions of Harming, but take extra damage from weapons enchanted with Smite, along with taking damage from Potions of Healing. Many of these weaknesses and immunities are a result of what category (see below) of mobs that the mob falls into.

Undead mobs


This group of mobs includes drowned, husks, phantoms, skeletons, skeleton horses, strays, withers, wither skeletons, zoglins, zombies, zombie horses, zombie villagers, and zombified piglins. These mobs are damaged by potions of Healing, healed by potions of Harming, and are immune to drowning (except for husks and zombies, which turn into zombies and drowned if drowning, respectively) and poison damage. Zombies, zombie villagers, drowned, skeletons, strays, and phantoms burn when under direct sunlight, unless they are touching water or wearing a helmet. Under the fire resistance effect, undead mobs still catch fire in direct sunlight but do not get hurt by the fire. All undead mobs except for drowned, phantoms, and withers sink in water. All undead mobs take extra damage from weapons enchanted with Smite, and are ignored by withers.

Most undead mobs have the ability to pick up items. Some can spawn wearing armor, or holding tools or weapons.

Aquatic mobs


This group of mobs includes axolotls, dolphins, squids, glow squids, guardians, elder guardians, turtles, cod, salmon, pufferfish, and tropical fish, but not drowned. They take extra damage from tridents enchanted with Impaling, and, except axolotl, do not cause pufferfish to inflate nor take damage from them. All aquatic mobs except dolphins are immune to drowning, and all except guardians, elder guardians, and turtles take suffocation damage if out of water for too long. Aquatic mobs have the ability to swim, whereas other mobs simply float on water or sink. In there is no in-game classification for these mobs.

Arthropods


This group consists of mobs based on, namely bees, cave spiders, endermites, silverfish, and spiders. They take extra damage and receive the Slowness IV effect when attacked with weapons enchanted with Bane of Arthropods.

Illagers


This group includes pillagers, illusioners, ravagers, evokers, and vindicators. They are immune to evoker fangs damage and ignored by vindicators named "Johnny" (except ravagers). They are hostile toward villagers, wandering traders, iron golems and players in Survival or Adventure mode. Witches, and vexes may accompany them in raids. Illusioners (and witches) can see players or targets through blocks.

Knockback resistance
Some non-boss mobs resist a percentage of knockback from attacks.

Advancements
Advancements are made when a player accomplishes something that is either rare to accomplish or sometimes easy to do so (such as Adventure for killing or getting killed by an entity).

Issues

 * For issues unique to specific mobs, see that mob's issues section.

Trivia

 * Renaming a mob "Dinnerbone" or "Grumm" using a spawn egg or name tag causes it to flip upside down.
 * Renaming a sheep "jeb_" makes its wool change color with a smooth transition between colors. Note that the sheep named "jeb_" drops only the color of wool it had when named (e.g., when a pink sheep is named "jeb_" and then sheared when its color has changed to blue, it still drops pink wool).
 * Renaming a vindicator "Johnny" makes it attack all nearby mobs, except other illagers.
 * Renaming a rabbit "Toast" gives the rabbit a new texture, as an Easter egg to xyzen420's girlfriend's missing rabbit.
 * Spiders, cave spiders, slimes, silverfish and illusioners are some of the few mobs that can see players behind walls.
 * Cats and villagers can see players with the invisibility effect.
 * There are many blocks in the game that do not take up a full block, such as trapdoors, and mobs actually see many of these as full blocks.
 * With some blocks, mobs mistake them for air, such as carpets, snow, and string.
