In the stone tower temple boss room. But you can also use it in any other boss battle once you have the mask =)
defeat the wizrobe in the snowhead temple. use bunnyhood to defeat him easier.
I believe its T is up G is down H is right and F is left.
Get on top of the hexagon square thingy and use Dins Fire to light all of the torches up.
No, you need to play it on either the N64 or you download it on to the Wii. If you do the latter, you will need to use the Wii Classic Controler.
You need to use a bomb or the blast mask to trick her out wait for her to walk out and after she a distance away run inside
GameCube n64 and 3ds or a Rom if you know how to use emulators
in the stone tower temple but you need to turn the temple upside down but before that get a key and don't use it . this is easier than getting the other key
you get bubbles(magic attack when your a deku) from your magic bar so use a magic potion/jar. the magic bar is the green bar below your health(just for people who are confused about where to find it)
Use the gibdo mask to pose as a gibdo and talk to each one they ask for certain items they are: Blue potion, Spring water, Magic beans, Deku nuts, Bugs, Fish, Hot spring water, Big poe ghost, Milk, Bombs.
You must go to Lon Lon Ranch. It is where the giant boulder is blocking the path. You can use the powder keg to blow it up on the first or second day or you can wait until the third day when it is gone. Once you get to Lon Lon Ranch go to the other end where you will find a building with Cuccoos ( Chickens ) painted on it. Enter and you will see a man sitting. Use the Broman's Mask to get all of the Wandering chicks to follow you. Once you have them all, keep using the mask until each has turned into a Cuccoo. Speak to the sitting man afterwards.
the only place I recall you can use the giant's mask is the room you fight twinmold in
You can see various things normally you wouldn't see like the goron ghost or platforms.
