I added a "related link" that might help you... It's an Ocarina of Time walkthrough that's still being worked on, but is finished with up to right after Dodongo's Cavern! It's on my favorite Zelda site.
Go to Dodongo's Cavern on Death Mountain and defeat King Dodongo. Hope i helped!
King Dodongo? When he opens his mouth to breath fire, throw a bomb in. Then attack. Try standing right next to the lava to avoid his roll.
You get the bombs from Dodongo's Cavern in Death Mountain.
The second monster you encounter is usually the Skulltula, as you run into Deku Babas on your way to the tree. The second boss is King Dodongo.
Ahoy, there. o/ Queen Gohma (Inside The Deku Tree) King Dodongo (Dodongo's Cavern) Barinade (Inside Jabu Jabu's Belly)
King Dodongo is quite simple. Wait until he opens his mouth and throw a bomb in it. Give him a good couple of slashes and run close to the middle stage.( near the edge of the lava) wait for him to roll into a wall then repeat the process.
Put a bomb in the center of the room.
King Dodongo rolls around this room in a repetitive pattern. Stand off to the side somewhere and let him roll right past you. When he runs into the wall and turns around to shoot his fire breath at you, throw a bomb (or bomb flower) in his mouth. Repeat this until he is dead; collect your heart container power-up and exit back outside.
Beat Ganon, der.
Keep heading through the temple freeing the gorons and after you get the hammer(I'm speaking about fire not dodongo, Incase you're talking about dodongo) The first room of the temple- Smash the statue next to the stairs, Head through some more- Boss key next to goron
You never meet Zelda's father in Ocarina of Time.
Dodongo's Cavern is on Death Mountain Trail hidden behind a giant boulder. To remove the boulder you must obtain the Goron Bracelet from the goron leader Darmania. Then use it to grab a Bomb Flower outside the village and throw it down onto the boulder, behind the boulder is the entrance to Dodongo's Cavern.
