When visiting Dragon Roost Island For the first time, do everything up until you get to toss Medli to the other side of the spring. Miss throwing her and make her hit a wall. Stars will appear like when you place a high bid in the auctions, and she will say "Link, I didn't know you were triplets" or something to that effect. This will not affect your adventure in any way if you toss her correctly the next time on the inclined rock facing, and the wind is blowing north.
