Creepers are common hostile mobs that will explode when close to the player.
Creepers naturally spawn in the Overworld on top of solid blocks with a light level of 7 or less.
Creepers drop when killed:
- 0–2 Gunpowder
- A random Music Disc if killed by a Skeleton.
- A Creeper Head if killed by a charged creeper
A creeper giving chase and about to explode.
Creepers will chase after any player, as long as it is within a 16 block (±5%) radius and ±4 blocks vertically. The detection range of creepers is reduced to half of their normal range (8 blocks) when the player is wearing a creeper mob head.[Java Edition only]
Creepers can climb up ladders and vines like any other mob, but do not do so intentionally.
When within three blocks of a player, a creeper will stop moving, hiss loudly, start flashing and inflating, and explode after 1.5 seconds. A creeper's detonation can be halted if the player gets out of the blast radius (7 blocks), including by knocking back the creeper or killing it. Creepers can be forced to explode by using a flint and steel.
Creepers will flee from ocelots and cats if one is too close, until they are approximately 16 blocks away from the feline(s).
A creeper's explosion has a power of 3 (but see an exception below).
If a creeper is inflicted with a status effect, its explosion will create an area effect cloud of the effect.
Creepers are never targeted by any mobs, other than the wither, the snow golem, and the vindicator named "Johnny." If they are hit by a stray projectile, they will only retaliate if they are not already chasing a player.
A charged creeper is created only when lightning strikes within 3–4 blocks of a normal creeper, which significantly increases its explosive power. Charged creepers are distinguished from normal creepers by the blue aura surrounding them.
Their countdown timers are the same as normal creepers, both in terms of range and time. With a power of 6, an explosion caused by a charged creeper is twice as powerful as the explosion caused by a regular creeper (see image). How close the creeper was to the lightning strike will not affect the size of the explosion.
Charged creepers have the same entity ID as normal creepers. The only difference is that the value of the boolean "powered" tag is set to "1" (true).
Charged creeper explosions will cause a zombie, skeleton, wither skeleton, or other creeper to drop the corresponding mob head, one per explosion. However, they will not drop their own head.
