??? - I'm really at a loss here!
Go to the Bombchu bowling Alley in Hyrule Market and start a new game. Knock down the first two walls. Now when you are done with the game,stand near the counter and face the alley. Hit the Up C button and look at the chickens. They're purple now! You can make a dog follow you at nighttime also, and make the purple light hit him, but it doesn't show up as well on the dog as it does on the chickens!!
