Also pigmen. Pigmen are swines. (Lost all my stuff in the nether again. Meh

)
I didn't really need more reasons to play on Peaceful setting, really. But thanks. I love the vindication.
Meanwhile, I found an NPC about ten minutes into my second session with that new world. WHEW. And it's right near a little bit of everything: jungle in one direction, forest in another, plains in a third, and desert in a fourth. Score! And, when I was in the one building with a ton of bookcases in it, ALL the villagers followed me into the building and milled around me, creeping me out.
So I offed every single one of them, and now I'm REALLY playing on Peaceful.
The only bad thing is that there are a lot of wolves around, and only a few chickens (and with the wolves, they'll be gone right quick.) No cows, pigs or sheep anywhere in sight. I know I can get sheep to follow me if I'm carrying wheat, but how far? Pretty sure the wolves have kept them away or killed them.
Also, I sometimes leave the night on, on purpose, so that I can see things like distant lights: NPC villages are easier to spot at night and lakes of lava as well, plus my own Hansel-and-Gretel torches.
Sorry you lost your stuff (again). I'm just relieved to have found a spot to put my stuff instead of carrying it all around and risking it. Because I'm clumsy and have fallen too far more than once.
Now I'm trying to find ways to regrow regular grass (so any sheep that spawn will stick around and have something to eat, even if I pen them up)...
