Woodland Golem

Basically what the title says. This is an idea to add a new golem type to Minecraft. This golem being a straight hostile golem (unless made by the player) then it becomes neutral. This is the Woodland Golem. It spawns in a woodland mansion and guards the place. I think that this is a good way to add more protection to woodland mansions and also a fun new reason to find woodland mansions. These golems may have a special thing they drop that can only be accessed by killing them or something. This could work as a new golem that protects igloos, jungle temples, desert temples, or other naturally generated structures as well.
