Now and then a chest walks off on its own. Treasure mobs turn up inside mineshafts, temples, strongholds, trial chambers, ancient cities, mansions, bastions, fortresses and end cities, and in the structures of Assorted Structures when it is installed.
Each one carries what that place's own chests would hold, anything from bread to diamonds, and drops all of it when it dies.

Taming
A wild one keeps away from players, but gold nuggets lure it in. Feed it nuggets and it may decide to stay.

A tamed treasure mob follows you and sits when told to. Sneak and use it to open it as a chest.
