Okay, so I finally found a lunar butterfly in the swamp cliffs area and I want to know if the swampland is the best place to find them. So if you find or have found them or any ultra rare item please report it here.
Also, I have found that bluejays seem to spawn more often in the forest colony area, and turtles in the fairywood and swamps.
can you maybe post screenshots of the ultra rare creatures? i'm afraid i'll run past the black dragonfly without noticing hehe. there's a few others I still haven't seen. can't remember where i found the lunar butterfly but I think it was somewhere around the forest colony.
