This add-on adds 9 new Minecraft MOB Spawners And they are craftable! But can not be found on randomly generated terrain. This add-on was created to make things a bit more easier for players!

This add-on is about More mob Spawners and a bit more heads in the game it adds:
1. Wither skeleton Spawner  2. Piglin head & Spawner 
3. Hoglin head & Spawner  4. Phantom head & Spawner
5. Slime head & Spawner  6. Witch head & Spawner
7. Creeper Spawner  8. Enderman Spawner & Enderman head
9. Guardian Spawner & Guardian Head
-------
These Spawners are craftable using the head of the mob of the Spawner.
(e.g. Creeper head from the creeper) And a few more items required to make the Spawner.
(You can check the materials needed for each Spawner in the crafting book guide)
The mob heads can be gotten by killing it's mob like killing a Hoglin or a phantom, it's a very low chance and it's very hard to get but using looting can speed up the process
NOTE: This Add-on does not use Player.json

As for the Slime Spawner it doesn't have a "head" It has a "Shield" which is what you can see in the picture above ^^
