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. Because of his sheer size, this beast cannot be killed, but rather avoided. By nailing him in the back with the Hookshot, Link will see more of the same, the Great Moblin will freeze, allowing for Link to pass right by, unscathed. Immediately behind the Great Moblin is the passageway to the Forest Temple.

Trivia

 * The Great Moblin's only appearance is within the Ocarina of Time, and only serves the purpose of halting Link's progression to the Forest Temple. If Link ventures into the Sacred Forest Meadow as a child, however, Moblins will be replaced by rolling rocks, and the Great Moblin will not exist.
