I haven't posted here in aaaages. Bad me for letting my community die. Well I'm a meanie so I'm going to remind you of its existance. =P
In OoT, you can do all kinds of funny things with the Ocarina. While playing, holding the analogue stick in different directions makes the notes sound funny, and holding R or Z makes them higher or lower. If you feel like randomly playing odd music like I do, this is....useful. Otherwise, it doesn't help. =P
Also, if you take old Link into the windmill and make him stand on the spinning thing inside, and let go of the stick and all the buttons for a while, he'll rub his arms like he's cold and then sneeze. How random.
