Mob

A mob is an AI-driven game entity resembling a living creature. The term "mob" is short for "mobile". All mobs can be attacked and hurt (from falling, attacked by player or another mob, falling into the void, 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 needs to "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 4 end crystals.

Players can also spawn mobs easily by using 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. $$, most passive mobs do not despawn, while most hostiles do. $$, almost all passive or hostile 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, etc.). Some mobs may be resistant or immune to certain hazards, such as Nether mobs, which are immune to fire. Mobs like cod, salmon, tropical fish, pufferfish, drowned, guardian, elder guardian cannot be drowned. 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 pathfinding 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.

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 on 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 and view their individual page.

Passive mobs
Passive mobs are harmless mobs that do not attack the player, even when provoked or attacked. Most of them are breedable and/or tameable.

Neutral mobs
Neutral mobs are sometimes passive and sometimes hostile toward the player. Many neutral mobs become hostile only when attacked first, but other neutral mobs have other ways of being provoked. Some may be naturally hostile with provocation.

Hostile mobs
Hostile mobs are dangerous, aggressive mobs that always attack the player within their respective detection ranges.

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. They also have a boss bar featuring their name and health. Boss mobs provide unique challenges but also equivalent rewards. Some players also consider elder guardians, ravagers, evokers, piglin brutes, Skeleton Horsemans and illusioners as mini bosses, even though they don't have a bar.

Upcoming mobs
Upcoming mobs are new mobs that are present only in development versions for an upcoming version. This excludes mobs that were announced (confirmed) to be added but yet did not appear in development versions. For announced mobs see Planned versions and for possible future mobs see Mentioned features.

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 also 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 $$.

Announced mobs
Mobs that have been mentioned by Mojang as confirmed or potential future additions.

These mobs were part of the biome vote that took place in MINECON Earth 2018 and the biome vote from MINECON Live 2019.

These mobs either lost the votes and were said to potentially be added in a future update, or will be added on the future.

Unimplemented mobs
See also: Java Edition Mentioned features

These are mobs that were planned to be added but either got replaced by other mobs or scrapped.

These mobs either lost the votes and will never be added in a future update, or have a small possibility to be added on the future (only the mobs that lost the mob vote on Minecraft Live 2020 and the event itself).

Mob vote
In two of the annual Minecraft events (MINECON Earth 2017 and Minecraft Live 2020), the public 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 glow squid, which is pending to be added.

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) 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 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, evokers, vindicators, and ravagers. They are immune to evoker fangs damage and ignored by vindicators named "Johnny". 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. Vindicators named "Johnny" attack ravagers, as they are not illagers.

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

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, and mobs actually see many of these as full blocks.
 * With some blocks, mobs mistake them for air, such as carpets, snow, and string.
