As I wanted to train Kiamu in building skills, I put him to clear the stream. But impossible to have any success, it was "No!", "No!", "No!", every time!
Looking at his "Likes/Dislikes", I saw that he dislikes.... wind!
(the place to clear the stream is up on the cliff, near the wind-flutes!
)
So I brought him back on a hut and he fixed it... easily!!
