I think it would be a neat addition if you could wax moyai with a honeycomb to prevent their movement. This would make it possible to use them in builds where you need them to stay in one spot. Of course you'd also be able to use a axe to scrape off the wax.

Have they ever messed any of your builds? They do that super rarely only on full moons. Plus they will rotate back

Oh no, they have not been problematic, i just thought it was a neat idea to consider!

Perhaps I am confused as to how the movement works? Do they return to their original spot after moving? I thought they would move to a new spot and stay there.

They just rotate, turning their head

I was in fact confused then, however having them move location too might not be a bad idea. Perhaps then waxable moyai would be more ideal.

Just a thought, although i really like the idea of them sinking into the ground and popping back up elsewhere like i originally imagined. Let me know what you think! 👍
