I got a treasure location from a villager that wanted some Fine arrows. The directions sent me to find an island in Kuikka lands. There were 3 large rocks arranged in a triangle. The treasure was buried between them. So, I took a punt, paddle, and shovel and went searching. Sure enough, I needed the punt just to get around out there and the shovel was required to uncover a treasure. I've not had one hidden this way before. It's usually on a cliff somewhere.
The other thing that I ran across was a herb called ROSEROOT. Never seen it before. So, cool adventure! Has anyone else run across either of these?
