Mob

A mob is a living, moving game entity. The term "mob" is short for "mobile". All mobs can be attacked and hurt (from falling, burning, attacked by player or another mob, falling into the void, etc.) and some of them can drown. Different types of mobs often have unique AI and loot.

Spawning
Mobs spawn in various ways. Most mobs spawn naturally, depending on their light level, habitat, and their surroundings, for example, most animals are found in brighter, outside areas whilst hostile monsters are commonly found in the dark (whether if it’s a cave, dungeon, mansion or at night). These mobs usually spawn upon chunk generation. Most animals including those that are passive, neutral and even hoglins have the ability to be bred by the player, creating offspring. Villagers also breed randomly depending on the time and the amount of beds (though they can’t be bred by the player). 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 they 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 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 in regard to the player as below. 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. Many 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 on sight.

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.

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 created with a spawn egg.

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

Unimplemented mobs
See also: Java Edition Removed features

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

Education Edition exclusive mobs
These mobs are exclusive to.

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.

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 effect of a Potion of Fire Resistance, undead mobs still catch fire in direct sunlight but do not take damage. All undead mobs except for drowned, phantom, and wither 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.

Water-based mobs
This group of mobs includes dolphins, squid, 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 water 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. Water mobs have the ability to swim, whereas other mobs simply float on water or sink.

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. Both types of spider are immune to the effects of poison. Silverfish infest infested blocks.

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 to villagers, wandering traders, iron golems and players. 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.


 * Iron golems: 100%
 * Shulkers: 100%
 * Squid: 85% when out of water
 * Ravagers: 75%
 * Hoglins and zoglins: 60%
 * Drowned, Husks, Zombies, Zombie Villagers, Zombified Piglins: 0–5% (determined upon spawning)

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