btw you can use logs, wood, and sticks for smelting- logs burn the longest out of them. While coal burns longer, you can regrow wood so you don't have to go looking for it if you run out (not that you will in singleplayer, but I imagine with enough people in multiplayer it's not going to be easy to get coal.)

Okay people, I started a new file and found these HUGE underground cave systems.
I kept on hearing monster noises in a monster-less place. I dug around because the monsters were probably there, in another cave, around me.
I kept digging and I found THIS.
The torch was placed by me, although the chests and cage were not. What is that cage anyways ? From what I've seen, the skeletons just appear/pop out of it.
Also, the noises heard were zombies, and I didn't find any yet.

It's a dungeon- the cage is a mob spawner. You can take advantage of it and build a contraption that kills the enemies and collect the drops, or you can destroy it and not have to worry about it. Also chests in dungeons can contain items that you can't get elsewhere.
