What is the interactable thing placed on some stones all over the second island and through half of the north part of the map? How do I interact with them?
No, other ones, without yellow spots. I mean things that looks like a buttons carved in stone. One is on route 113 between girl in red with umbrella stuck in her head and twins. I tried to get a picture, but it doesn't let me. Just fails to download. Those stones even say "It seems like you can do something here."
