Dongorongo

Dongorongo is a Dodongo-like boss in, and resides in the fifth dungeon, Goron Temple.

Strategy
Link enters a room with quicksand surrounding the center platform. Link cannot cross the quicksand, as there is no bridge. However, Gongoron comes out of a hole in the wall behind Dongorongo and offers help to Link. The objective is to dodge the fireballs that Dongorongo blasts from his mouth and to avoid him when he charges at Gongoron. When the young goron dodges the charge attack and Dongorongo bashes his head against the wall, he gets stunned for a few seconds, Gongoron can slam him from his side into a state where he is stunned for several seconds, which can be done by either tapping the boss's back rapidly, or by simply rolling Gongoron around to Dongorongo's side, as well. During this Critical Point, Link must send a Bombchu into Dongorongo's mouth, which will then explode inside of him.

As a word of caution, Link must occasionally take control of himself during Gongoron's battle against the boss as he can be attacked by monsters that assist the beast.

After three Bombchus, Dongorongo falls down, a bridge appears and Gongoron walks out of the room. However, just as Link crosses the bridge, Dongorongo wakes up, and some of its armor breaks revealing a large blue crystal, which is his weak point. Dongorongo will attempt to inhale Link and when he does this, the hero must throw a Bomb into his mouth. Once incapacitating the boss again, Link proceeds to attack his weak point until he stands up again. Repeating this a few times results in the true defeat of Dongorongo.

Trivia

 * Dongorongo is somewhat similar in appearance to the Pokémon Bastiodon and Heatran, from the Pokémon series.
 * Just as the Boko Babas from are thought to have evolved from Deku Babas, it's possible that Dongorongo is an evolutionary descendant of the classic Dodongo.
 * The crystalline growth on Dongorongo's back is almost identical to the Crimsonine barring the color, suggesting that the Pure Metal may have somehow been extracted from it or another member of its species. However, Zauz mentions that there is only one of each Pure Metal in the world.
 * Dongorongo's name is most likely a cross between "Dodongo" and "Goron" because it possesses the lizard-like body of a Dodongo, and the rock-formations of a Goron.
 * The method to defeat Dongorongo is strikingly similar to the method used on King Dodongo from Ocarina of Time.
 * When Dongorongo is defeated, the sound it makes before falling over is the same as the one made by the dying Molgera in The Wind Waker, although slowed down slightly and cut short by a few seconds.
