Decoding Peaceful Mode: What Vanishes in Minecraft’s Easiest Setting?

Ah, Peaceful Mode. The sanctuary for builders, explorers, and those who simply prefer their Minecraft experience without the constant threat of becoming zombie dinner. But what exactly gets the boot when you switch over to this idyllic setting? The short answer is: all hostile mobs. But the details are more nuanced than you might think.

In Peaceful Mode, hostile mobs simply don’t spawn naturally. This includes the classic creepers, zombies, skeletons, spiders, endermen, witches, slimes, magma cubes, blazes, ghasts, phantoms, drowned, evokers, vindicators, ravagers, pillagers, guardians, elder guardians, shulkers, the Warden and even goats (that can headbutt you). Think of it as a monster-free vacation in the blocky universe. However, keep in mind this only applies to natural spawning.

Understanding the Nuances: More Than Just Mob Vanishing

It’s critical to understand the exceptions. Peaceful mode doesn’t magically erase all hostile entities from existence. Think of it more as preventing new threats from entering the game.

Here’s a breakdown:

Pre-Existing Mobs: If you switch to Peaceful Mode while hostile mobs are already present in your world, they don’t immediately disappear. Instead, they are instantly despawned. This means they are removed from the game entirely.
Spawned by Command/Spawn Eggs: Mobs spawned using console commands, spawn eggs in Creative Mode, or through mob spawners (like the ones found in dungeons) will still appear, but they will instantly despawn the moment they spawn. This applies even if you try to trap them or keep them in enclosed spaces.
Boss Mobs: Boss mobs like the Ender Dragon and the Wither will still spawn if you summon them by placing the end crystals or wither skulls/soul sand respectively. However, they take damage over time until they are defeated. This essentially renders them harmless, although fighting them can still be done, if desired, to obtain their drops. Note that the Wither is incredibly dangerous when it explodes after being summoned, even in peaceful mode, due to the terrain damage it causes.
Passive Mobs: Passive mobs such as cows, pigs, chickens, sheep, horses, villagers, and the like are not affected by Peaceful Mode. They will continue to spawn and behave as usual.
Neutral Mobs: Neutral mobs that are not aggressive by default will still exist. This includes mobs like endermen and wolves. However, if provoked, these mobs will not attack. They are essentially rendered passive. Endermen will teleport away and wolves will just stay nearby until you leave their range.
Iron Golems: Iron Golems spawned by villagers will act as normal, however you need a villager with a profession to breed the golems.

Essentially, Peaceful Mode creates an environment where the game actively prevents any new hostile threats from appearing. It’s a great way to learn the game mechanics, build elaborate structures, or simply relax without the constant pressure of survival.
