CREEPER

if you have played minecraft for a while you may have known of Creepers. as we all know, creepers creep up on you and within half  a second you get blown up! so let me get to this in a little bit more detail..



Creepers can spawn in 3 ways. creepers will spawn in the overworld on top of solid blocks with a light level of 7. the second way is if the creeper is spawned with a spawn egg taken from the inventory and the last way is to use custom spawners.

creepers drop 0-2 gunpowder and a music disc if kiled by a skeleton. they also drop there head if blown up by there 2nd kind known as the charged creeper which we will get to in a second..

Creepers will chase after you as long as it is in a 16 block radius. when within 1 block of a player, they will make a hissing noise (if so i would back off..) then it will start to flash and inflating, after 1.5 seconds it will blow up on your face! however, this detonation can be halted if the player steps back 4-5 blocks also knocking back the creepy fellow is also possible as long as your on a 4-5 AWAY from the creeper you're fine! 

Suprisingly, Creepers will flee from ocelots/cats if there too close the creeper will have 'RUN RUN RUN!' on their head untill it is almost 25-30 blocks away from the ocelot/cat! 

now as i said before its time to learn about charged creepers! so, charged creepers are born only if the creeper is struck by lightning. Charged creepers can only appear with that method there is 1 method which uses commands so i will leave the command below in case you guys wanna play around with them! the only way to seperate charged and normal creepers is that the charged creepers will have a blue aura and normal ones dont. also the biggest thing to note is that a charged creeper's explosion is WAY bigger than a normal one. 

Charged Creeper Command: /summon Creeper ~ ~ ~ {powered:1}
