How to create an iron golem in minecraft

Items you need are: 1 Pumpkin and 4 Iron Blocks (36 Iron Ingots)

Start your Iron Golem with a single Iron Block on the ground. Make sure there are no other iron blocks touching it

Add a second Iron Block on top of the single iron block on the ground. Make sure no other Iron Blocks are touching both blocks

Add two iron blocks in the shape of a T. There is no necessary order in which the side blocks need to be placed in.

After that, add a pumpkin on top of the middle iron block. This should spawn your Iron Golem

This is the finished product of the build and your Iron Golem. Iron Golems are capable of attacking zombies and at extended ranges.

This is because Iron Golems naturally spawn in Villages, where they protect Villagers from Zombies. If they didn't, Zombies would eventually kill the villagers, infecting them and making them zombies
