So for the past few years, Minecraft has had the same different mob heads: creeper, zombie, skeleton, wither skeleton, an ender dragon. . Well, why not have a way to obtain ALL of mobs heads in survival. Below I have a few suggestions on how a few could be obtained
Enderman: killed by a shulker.
Shulker; picked up by a endermen then killed.
Drowned: They are at the front of a shipwreck with a 1% chance of spawning.
Charged Creeper: obtained when a wither killed a charged creeper.
Spider and Cave Spider: found in abandoned mineshafts with a 5% chance.
Wolf: Killed by a skeleton.
These are only certain suggestions. If I get feedback or come up with anyone, i will update it,
This could also be useful to give people more of a BIG challenge in Minecraft. For people with big survival worlds, this could be useful for them as another project.
