It’s unclear. Some are more human than others. Only their leader seems to be fully wooden with magic eyes. I can’t recall if any of them eat or drink.Why would he want to remove that?

I feel like if they've replaced their bodies with wood and other inorganic materials that they wouldn't need to eat/drink/breathe, but that's me.
