Great Moblin

A Great Moblin is the final obstacle standing between Link and the Forest Temple in The Legend of Zelda: 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 wields an enormous club, which creates dangerous shockwaves upon striking the ground. 

Strategy
By far the easiest way to kill it is to shoot it with the Bow, or if you do not have it yet, to unleash Bombchus at it. If you have neither, you will have to run at it, dodging the shockwaves it sends at you in the process, and slash it with your sword. It will take some time to recover from this blow, and it may be a good idea to get behind it during this time, because it's fairly immobile, so it won't be able to turn around quickly and face you. If you wish, you can make an easy getaway at this time; however, it will only take another two slashes to take it down, and since you're behind it, it won't be able to retaliate.

Upon death, it will always drop several Rupees, which will either be red, blue, or a combination thereof.

Trivia

 * The Great Moblin's appearance is within Ocarina of Time 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 mad scrubs, and the Great Moblin will not exist.
