The Legend of Zelda: Twilight Princess GameCube Cheats

Control a Cucco:

 Unlike other Zelda games, in Twilight Princess, if you hit a cucco a few times you'll be able to control it.  Beats getting murdered by chickens. 
Extra Lures:

 You can get the Frog Fishing lure by winning 8 games of roll goal at the fishing hole.  The Sinker lure can be found after catching a Hylain Pike, Hyrule Bass, and a Ordon Catfish in the fishing hole area.  After that, go to the corner closest to the house and fish there to get the Sinker lure.  Don't let Hena see you use it though, she'll take it away. 
Fish up a Bottle:

 Near the sign at the fishing hole that says 'no littering', fish in the darker spot of water and get yourself a nice Bottle. 
Wallet Upgrades:

 To get the Big Wallet, catch a golden bug and give it to Agatha in Hyrule Castle town.  For the Adult Wallet, you'll have to bring her all 24 of the golden bugs. 
Iron Boots glitch:

 This trick works anywhere with a magnetic ceiling, like the Death Mountain mines.  First, set the Iron Boots to a D-pad spot.  Then, put them on, and while flying toward the ceiling, press the minus button and assign another item to the slot the boots are in.  When you come back to the action, you'll be on the ceiling anyway and running faster to boot.  To get down, just put the boots on again.
Get Hawkeye:

Go to Kakirico Village and go go to the goron by the bomb shop. He'll hoist you up, go to the top of the little tower. The kid who stole your wooden sword will be there. Talk to him he'll want you to show him your bow. First you have to shoot to targets, piece of cake. Then he'll want you to shoot a pole on the tower. when you do that go to the malo market and the hawkeye will be for sale.  
Donation Discount:

 After you give a 1000 rupee donation to the Goron in Malo Mart, talk to the old Goron outside and complete the quest he offers you.  Finishing it takes the second donation from 2,000 rupees to only 200. 
Worldwide Fairies:

 Once you discover the Gerudo Mesa and the Cave of Ordeals, you can complete rooms to make fairies appear around Hyrule.  See below for a bit of a guide.
