The Legend of Zelda: Ocarina of Time Glitches

Purple Cuccos
Go to the Bombchu Bowling Alley in the Hyrule Market. Pay to play, and then get to the part in the game where you have to get your bombchu past the little and big chickens. Finish the game and then walk up to the Juke Box, and slowly turn around to where you are in a sort of first-person perspective. If done correctly, both chickens should be purple.
