Boxmen

If an End Update is to be made, and if Enderman Societies are to be added, I think that the Endermen should wear boxes on their heads. Endermen get angry when you look into their eyes, so maybe in their culture it’s offensive to look there. If they were to normally wear boxes, it would be taboo to look into their eyes, and that would be the explanation for why they get so offended. I think that there could also be an explanation for normal Endermen, which is that they lose their boxes when they teleport around, and that they are outcasts in Enderman society. Maybe to trade with these “Boxmen” you’d have to wear a box of your own, obtained from a new biome in the End made up of Box Bushes. These boxes could be decorated with different designs and dyes, and could be worn on the head, or given to another Enderman for them to wear. For trading, you’d have to bring them a “Barter Box”, which could be filled up similarly to a Bundle. They could give you a Barter Box of their own, with different loot inside depending on the value of the Barter Box you gave them. Maybe if you gave them a Barter Box with low value, they could decline your trade or even retaliate by attacking you.
