Villagers: Far From Home

Have you ever wanted to bring your villager friend along on a journey, whether it be to the heights of the tallest mountains, the most beautiful cherry blossom biome, or to a.. swamp? _{(Sorry villagers, I'm gonna need those mending books >:D )}

Well, have no fear. Now, you can bring your villager friend along with you. No, not on your head, silly. No, not trapped inside of an egg, either. On a leash?! Are you crazy?! _{So inhumane.. @_@} No, instead, your Villager friend will travel on foot alongside you, akin to bringing your best friend along on a quest to kill the Ender Dragon! Except this friend can't help defend you... or, for that matter, defend himself... huh.

How does it work?

To get your villager friend to follow you, he has to trust you first, of course. Trading with him until he's at least Journeyman level should do it. Once you guys are best buds, simply offer him an emerald by shift-right clicking him while holding one. Once you guys are ready, he'll follow you on your adventure, wherever you go! Unless you fall into lava. Or off a cliff. Yeah, he's probably not willing to do that.

If you want him to stop following you, all you have to do is let him know by simply shift-right clicking him once more. Just make sure you're not holding an emerald or he might start following you again. Yeah, they're kinda clingy like that.

Sometimes, if you take too long and he gets tired, he'll stop following and will probably start walking back home to get some rest. So, if you're planning on taking an extra long hike with your villager friend, make sure to bring some extra emeralds to bribe persuade your villager friend to stay with you.

Happy villager transporting!

TL;DR

Shift + Right-click a level 3 (journeyman) villager while holding an emerald to get him to follow you.
Shift + Right-click without holding an emerald and he will stop following.
Villagers will automatically stop following after some time. Simply Shift + Right-click with an emerald again.
