This mod adds the ability to tame Endermen by feeding them a Chorus Fruit (can be changed through datapack). Tamed Endermen tend to be a bit possesive, as they will try to always be with you, even sometimes following you into water. They are so obsessive that to even stop them from following, you have to tie them to a fence with a Lead - this will stop them from teleporting too. They are so jealous that they'll even attack other Tamed Endermen with very little provocation. Because of this, it is best to only have one Tamed Enderman at a time. They dislike the daylight, and will teleport around more frantically. Additionally, they tend to be rather lonely and clingy, so they may release hearts whenever you rejoin the world or respawn. Lastly, if their description so far hasn't convinced you yet, do remember that even if tamed, they are still dangerous monsters. It's unsafe to sleep with them around.
