A hamaknocker is a rare neutral monster that melee attacks entities that attack it, when it dies it explodes which can destroy blocks and cause massive amounts of damage.
It spawns naturally in Mushroom Island biomes, although it is very rare to find.
On Death
Ham: 1-3
Gunpowder: 0-2
XP: 5 (when killed by a player or tamed wolf)
A Hamaknocker remains hostile towards the player or an iron golem while it is nighttime; otherwise, it does not attack unless attacked first. However, Hamaknockers will pursue targets regardless of day or night in retaliation for an attack.
Using flint and steel on a creeplet causes it to grow rapidly and explode immediately.
Attacking a Hamaknocker will cause all Hamaknockers within 16 blocks to become aggressive, and defend it.
It attacks with melee attacks, causing 3 damage per hit, however when it dies it explodes with the same power as a common creeper.
Charged Hamaknocker
Charged hamaknocker are stronger versions of hamaknocker. They are distinguished from normal hamacknockers by their blue aura surrounding them, and their explosion power is significantly increased.
A charged hamaknocker is created when lightning strikes within four blocks of a normal hamaknocker.
