Cowboys in Minecraft!

You just need to add cowboys to vanilla Minecraft!
This is a friendly NPC (like merchants) that travels on horseback. If the player is also on horseback, you can attach a cowboy to you and he will travel with you (only when the player is on horseback). You can add several cowboys to your squad, for example.

Not just in Mesa. Cowboys should be everywhere. There can't be a biome where there are no cowboys. Cowboys are now even conquering space (there is such a space company)
