Bongo Bongo

Bongo Bongo is a mysterious creature which guards the mysteries of the Shadow Temple. It is by far the weirdest boss yet to appear in a Zelda game. If you play the game normally, he is the next-to-last Temple boss to cross your path. To defeat him, equip the Lens of Truth, stun his hands with arrows to reveal his giant eye, shoot the eye with another arrow and hack it with your sword. Once you repeat this process enough times, this evil will be no more.
