Dodongo
Dodongos are carnivorous dinosaurs that appear in Zelda games in several different forms. According to Nintendo of America, they resemble gigantic iguanas, move slowly and can breathe powerful blasts of flame. They first appeared as both bosses and normal enemies in The Legend of Zelda, then reappeared in different forms in A Link to the Past, Ocarina of Time, Majora's Mask, Oracle of Seasons, Four Swords Adventures and Twilight Princess.
In A Link to the Past, Dodongos do not have armor. Dodongos in Ocarina of Time and Majora's Mask are two-legged (while King Dodongo in Ocarina of Time had four legs), fire-breathing creatures. The Gorons in Ocarina of Time use Dodongo hides to make the heat-resistant Goron Tunics, and mine within Dodongo's Cavern, once a Dodongo nest, until it is overrun by Dodongos led by King Dodongo. In Oracle of Ages and Oracle of Seasons, Dimitri is a friendly Dodongo character. In Twilight Princess, Dodongos are gecko-like creatures that breathe fire but must be defeated by attacking their tail or shooting them in the mouth with an arrow.
Other types of Dodongos include Baby Dodongos, which are infant, worm-like creatures which explode when attacked, and Big Dodongos, which are larger versions of normal Dodongos.
IGN called it an "awesome lizard dude" and a "deadly, fire-breathing creature", commenting on how awesome the boss fight was.
