In this video I will be showing you how to make an iron golem. They are easy to make and can help you against zombies or other monsters like spiders, skeletons, drowns, etc. Never put them in deep water
because they will just sink to the bottom but it won't drown and it's really hard to make them go in water anyway.
Also if you have any suggestions of a video I could do then you can write that down in the comments.
