FOSS gamedev and creative worlds

I would like more mobs in minetest but I do not want to copy the minecraft mobs, I want mobs minetest. So I have 2 ideas for you when it will be one near you, spit lava the other is a ball when you touch it you perder life I would like a mod for this or I would like this mobs in the futur version of minetest (if you've got others ideas put it in this topic )

You forgot http://forum.minetest.net/viewtopic.php?id=4167
It adds multiple types of a "villager" and works pretty good.
