Dodongos are monstrous reptilian beasts that have made frequent appearances across the Legend of Zelda series. Its appearance has changed somewhat over the years, but it is commonly described as resembling a triceratops or even a rhinoceros. It has a thick, scaly hide that serves as natural armour, protecting it from any form of attack. It is also capable of spewing fire from its mouth.
Though its hide is impenetrable, the Dodongo is by no means indestructible. Its mouth is its weak spot; when it is about to unleash its flame breath attack, it takes a deep breath and can suck in any loose objects in the vicinity. Link can use this window of opportunity to throw a bomb in the beast's mouth, damaging it from the inside.
