you need to get both clawshots. you should find the other one in the sky temple. you can use an online walkthrough if you're lost.
there isnt an alter in twilight princess your thinking of spirit tracks.
there isn't one
yes it is all it has to do is pass customs and all that
you need to pass four temples before getting the master sword.
If you are far enough in the game you can lure fish or just explore to find more heart pieces
To get through it, take out the lantern and swing it around until the the purple stuff is gone.
If you mean how to get through the first part, you have to try once (unsucessfully), go back, and you will have to get iron boots after saving your horse from some monsters.
To obtain the pegasus boots in Link to the Past, you will need to pass the first dungeon and go to Sahasharla, AKA the man in the house by the dungeon. He will give you a speech and give you the boots. Hope this helps! ;)
Because I do not remember the exact details of the game, I shall provide a link to an internet walkthrough that I use myself in the Related Links section. The walkthrough is very good aside the occasional typo, but the errors are not so egregious they detract from meaning.
After completing the Forest Temple in "The Legend of Zelda: Ocarina of Time," the next dungeon is the Fire Temple located in Death Mountain. You will need to pass through Goron City to access the temple.
Well, you have to attack the Gorons until the curl up. then, you can climb on them and they will launch you up. Make sure you tilt the joystick towards the next level, otherwise you will have to beat the Goron again. Just repeat the process until you reach the top.
its not called the 'Fire Temple' in twilight princess it's called the Goron Mines and if your having difficulties I'd advise checking out this walk through I've linked for that temple: Twilight Princess was one of my fav and most entertaining games of the Zelda series if you have anymore questions feel free to ask. :)
