Mobs

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.

Many mobs despawn (cease to exist) after a certain amount of time if far enough from the player. In Java Edition, most passive mobs do not despawn, while most hostiles do. In Bedrock Edition, almost all passive or hostile mobs despawn.

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.

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

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