It would be super awesome if we could export mobs with bo3tools! I know @NLBlackEagle asked for this in this post...
Why it would be super awesome, you might ask yourself
Well, yes, I could use biomes or spawners to spawn mobs... But I don't want my players to build massive mobfarms out of my structures. If these mobs get killed, too bad. But that way if my players stumble upon a merchant with horrible trades they can't just kill it to get a better trade, if you know what I mean. It would be nice if my gingerbread witchhut would be occupied by "Priscilla Cockroachcruncher", the witch. You could build your own villages, without having to make it a biome or set a spawner.
