Dodongos are powerful creatures who appear in The Legend of Zelda series. They are a hulking species who spew fire out at their opponents. They usually can be killed by tossing a bomb in their mouth. They can't be killed by standard sword attacks, seeing how thick and tough their skin is, though the insides are much more vulnerable, which is why they can be killed once they've engulfed a bomb. They are usually hated by the Gorons who often lives in the same areas as the Dodongo and must regularly deal with them as a result.
The Legend of Zelda
Ocarina of Time
In The Legend of Zelda: Ocarina of Time, Dodongos appear throughout Dodongo's Cavern. They breathe in as they aim toward Link, expelling fire toward him. While expelling flames, they must stay in place, allowing Link to damage their tails, which acts as their only weak spot. Dodongos can also spin their bodies to swing their tails at Link as a mean of attack. While a Dodongo breathes in, Link can also throw a bomb into their mouth to damage them. A special Dodongo named the King Dodongo also serves as the second boss in the game.
In The Legend of Zelda: Majora's Mask, Dodongos can be found in Termina Field near the entrance to the Snowhead region. They are virtually the same as their Ocarina of Time variant and share the same weaknesses.
A Dodongo appears as the boss of the Snake's Remains in The Legend of Zelda: Oracle of Seasons. Link must equip the Power Bracelet to pick up and throw the Dodongo into the floor spikes after bombing it. Additionally, a friendly Dodongo named Dimitri can be ridden in both Oracle of Seasons and The Legend of Zelda: Oracle of Ages.
Four Swords Adventure
In The Legend of Zelda: Four Swords Adventures, a Dodongo is fought as a boss in the Tower of Flames. It mainly attack by emitting fire from its mouth and the Links can damage him by throwing bombs inside it like in the other games.
In The Legend of Zelda: Twilight Princess, the Dodongos appear as Gecko-like creatures and can be found in the Goron Mines, Cave of Ordeals and various Lantern Caverns. Link can defeat them by using his sword, throwing bombs into their mouth or shooting Arrows into their mouth.

"A giant rhinoceros. It hasn't got so much attacking power, but it bounces off attacks with its thick hide."
"Watch out for its fiery breath! Use Z Targeting techniques!"

"What?! Don't you know about the Dodongo? It moves slowly, so you can circle around to its backside. Got that?"

"That's a Dodongo! It moves slowly, so you should be able to circle around to its backside. Got that?"
