Wandering Trader Breed

An unemployed villager should be able to become a Wandering Trader if you place a llama near them. The llama will automatically gain a chest and a carpet, and will be put on a lead that the villager holds.

You can right click the wandering trader to make them go out and explore, and can choose if you want them to go on a 'Short', 'Medium', or 'Long' adventure. The longer the adventure, the better loot they may bring back. Ringing a bell while they are gone will force them to start travelling back. When they come back, you may trade emeralds for the items they found on their adventure. To restock, they must go on an adventure again.

This would be a very unique villager breed I feel, along with adding more use to Wandering Traders, because they usually just become a nuisance if they visit you.
