Dodongo (The Legend of Zelda)

Dodongo is the second boss of the The Legend of Zelda is the earliest form of a Dodongo, which in this game resembles a Triceratops. The Dodongo in the The Legend of Zelda is vulnerable to what all Dodongos are vulnerable to, bombs. A bomb ingested by the creature will explode inside its stomach. Two bombs will kill the beast, giving Link the second piece to the Triforce of Wisdom. If the Dodongo walks into the smoke left after a bomb has exploded, it will be stunned and become vulnerable to Link's sword. The old man hints at this by saying "Dodongo dislikes smoke".
