Copper Golem

A copper golem is a buildable passive mob that takes items out of copper chests, and attempts to store them in nearby wooden chests and trapped chests. A chest examined by a copper golem must either be empty, or contain the item type it is holding, for the golem to place anything inside of it.
If not waxed, a copper golem oxidizes over time and eventually turns into a copper golem statue, dropping its currently held items.
