King Dodongo

King Dodongo's gaming debut was in Ocarina of Time. He is the second boss. You fight him in a room with a lava pit in the middle. And if he doesn't move, it will burn Link to a crisp. All Link has to do is throw a bomb into its mouth while it is preparing to breathe fire at Link. Then when it falls to the ground, give it a slash with his sword. Repeat twice and he's dead.
