Pilzadam's simple mobs has been a great addition to Minetest over the years and thankfully many people have built upon his work to create the latest mob api with many new features and items...
The API itself is a standalone mod which players can use to add their own mobs to the world through mob-packs. This must be installed and running for mobs to work.
