Dodongo's Cavern

Dodongo's Cavern on Death Mountain is the second of three dungeons that young Link must visit in order to acquire the three Spiritual Stones in Ocarina of Time. The cave has a great amount of rocks in it, which the Gorons that live nearby eat, and it is used for mining food for them. Prior to the events of the game, Ganondorf came to Death Mountain to get the Goron's Ruby from Darunia, the chief of the Gorons, who refused. Because of that, Ganondorf infested the cavern with Dodongos and sealed the entrance with a boulder.

Link, who came to Death Mountain to get the Spiritual Stone as well, was, unlike Ganondorf, able to gain the trust and respect of the Gorons. By using a bomb to destroy the boulder blocking the entrance, he was able to enter the cavern and went through it, defeating the creatures all the way through, up to King Dodongo, the boss of the dungeon. In return for this he was able to receive the Spiritual Stone from the Gorons and proceed with his quest.

The inside of Dodongo's Cavern is mostly dark, though several rooms of it show signs of being used, having bridges and statues around them. Others are smaller and darker, much like normal caverns. It is home to lizardlike creatures like the several varaties of Dodongos it was named for as well as several stronger Lizalfos. Inside the cavern many Bomb Flowers grow as well.

As a side note, the map items in the N64 Zelda games, when taken from a chest, show a map of Dodongo's Cavern on them.
