Different special mobs spawn in different dimensions, and they have some special abilities.
For more detail
see my PMC project page to know useful commands and the special mobs.
Installation
If you are playing the vanilla version, just download the data pack into the data pack.
If you are playing server, download the data pack to the data pack folder of the world folder.
If you are playing the forge/fabric version and want to install this data pack with the Curse Forge app, I suggest you install another mod Global Packs. This mod sees the resource pack folder as the data pack folder so that you don't need to copy it to the data pack folder by yourself after installation.
