Selective Mob Spawn

Take complete control over which mobs appear in your Minecraft world with Selective Mob Spawns! That single sentence essentially sums up the entire concept behind this handy addon.

Upon loading in, you receive a special book that allows you to disable from spawning any mob in the game. For instance, you can easily ban annoying mobs like Phantoms if you can't stand them. Naturally, blocking certain mobs from spawning means you'll lose out on farming their item drops, but you can always re-enable them whenever you need to.

Additionally, the addon gives you an option to toggle off either the adult or baby variants of any mob entirely.
