The Legend of Zelda: Ocarina of Time Easter eggs

Your own custom end music
Go to Lake Hylia as a kid. Go to the two scarecrows. Talk to perrie. When you take out your ocarina, the staff will appear and you can play a song. It can be very long. (53 notes) Anyway, after you play it, he'll say he likes it. After that, finish the game. At the end, wait until it says "The End." None of your buttons do anything and you have to reset or turn the game off. Well don't do it right away. If you wait, and you created the extended scarecrow song, you will hear the song play.
