The one atop Denadoro Mountains will give a Magic Tab if talked to four times. It'll first say: "Mountains're nice." Then: "This's the life." Then back to what it first said. Finally, he'll say: "Man, you're nosy. Here, take this." and give you the Magic Tab. If you talk to it after, all it'll say is "Mountains're nice."
Also when checking a bush in Guardia Forest in the middle ages a Kilwala will jump out and flee leaving a Shelter behind.
