Great Moblin

A Great Moblin is the final obstacle standing in the way of Link and the Forest Temple in the Ocarina of Time. The Great Moblin easily surpasses the height of his Sacred Forest Meadow counterparts, and with that he also boasts new techniques in an effort to kill Link, and protect the sacred Forest Temple from entry. The Great Moblin weilds an enormous club, which creates dangerous shockwaves upon striking the ground. 

Strategy
Despite his size, the Great Moblin is relatively easy to defeat, if desired at all. To kill a regular Moblin, one would Hookshot it in the back, stunning it, in order to go in for the kill moments later with the Master Sword. Well, when you first meet the Great Moblin, you cannot hookshot him in the back because he is facing away from the temple and directly at you, ironically because he can't turn around, thats the easiest way to defeat him. Just run up on the left or right side, and when he swings his club down, just run to the opposite side of the pathway. Keep doing this until you run past his feet, turn around and just slice the back of his legs with your sword. He goes down pretty quick and your reward? A lot of rupees. Immediately behind the Great Moblin is the passageway to the Forest Temple.
