Golems will automatically spawn in NPC Villages naturally, provided there are 15 villagers. It does not even have to be a naturally generated Village; as long as there are 15 villagers and a house, an Iron Golem will spawn.
The player may create them using blocks in a similar fashion to Snow Golems. To do so, the player must place 4 Blocks of Iron in a T-shape, and then place a Pumpkin or a Jack-O-Lantern on top. This is equivalent to 36 Iron Ingots, making creation somewhat of a task. They will always spawn facing south. Does not always work.
- Iron Golems do not attack creepers.
- Sometimes Iron Golems hold out roses to the villagers.
