How big is that house? o.0
In the latest 1.2 snapshot, mobs drop some items extremely rarely such as :
- Skeletons drop a bow or an enchanted bow.
- Zombies drop an iron ingot, iron helmet, iron shovel or an iron sword.
- Zombie pigmen drop a gold ingot, gold helmet, gold sword or an enchanted gold sword.
- Endermen drop a diamond gem.
Don't get too excited, I tried it, killed around 30 zombies, only got one iron ingot. But still it's quite nice
