Kodongo

Kodongos (originally known as Kodondo) are small reptilians that appear in with an appearance similar to a rhino or triceratops, much like a Dodongo.

Characteristics and Weaknesses
Kodongos often appear behind low barriers, where they walk back and forth occasionally breathing bursts of three fireballs. These fireballs can reach beyond the barrier, but it is difficult for Link to hit the Kodongo. The fireballs will burst into flame when they impact on something, so they can temporarily block off short passageways with their flames. The Kodongos themselves are weak, and can be defeated with a single sword stroke, although they are invulnerable to other attacks like the Boomerang. Green Kodongos appear in the Palace of Darkness in the Dark World, where they live in a pitch black maze-like room, making their attacks more dangerous, but they themselves are no stronger than the red variety.

Trivia

 * Kodongos were originally known as "Kodondo" in the Japanese guide for the SNES version of the game, but were renamed Kodongo in the GBA version. Whether this was to correct a spelling mistake or simply to make the connection to Dodongos more obvious is unknown.
 * Kodongo literally means "Little Dongo" in Japanese.
 * Dodongos and Kodongos are probably related, but prior to A Link to the Past, Dodongos did not breath fire. In games afterwards, such as Ocarina of Time, Dodongos gained the ability to breath fire much like a Kodongo.
 * Despite being similar to a Dodongo, Kodongos are completely immune to Bombs.
 * Kodongos first appear in the Tower of Hera, while a similar tower in, the Tower of Flames, is home to fire-breathing Dodongos.
