WARNING: Setting the "MobGriefing" gamerule to "false" will stop the golem from doing absolutely anything.

HAY GOLEM

You can also give "Bone Meal" to the Hay Golem to speed up the fertilization process—much more efficient than a villager. Yes, sir!

Watching it work is so fun! With "Bone Meal", it speeds up crop growth so you can get more resources, and it will prioritize this task. It doesn't need to sleep!

The Hay Golem will look for a chest to store what it has collected, so remember to place a chest nearby for it to work properly.
