This mod adds cute little mandrakes to your world. You can find mandrake bulbs in the stronghold, which you can plant and grow in a flower pot to grow your very own mandrake. To release the mandrake, simply wait till it has matured, then break the pot. Mandrakes will scream at you if you hit them, causing deafness. And no, you cannot tame these guys; it's a wild plant- what'd you expect.
