Diababa

Diababa is the Boss of the Forest Temple in. It is a three-headed Deku Baba, with one massive head with a hidden eye inside its mouth.

Characteristics
After Link enters Diababa's chamber, a large room with four waterfalls and a pool of poisonous water containing a large tree and two logs, the water will start to bubble and Diababa will emerge from the water.

The beginning of the battle starts with only the two smaller heads. Bomblings can be seen perched on logs floating in the water. Link can use the Gale Boomerang to make them collide with each of the two heads, with a single hit defeating each one. The heads will attack with a bite that can be easily avoided.

The second phase of the fight begins when the larger head bursts out the water. After a few seconds, Ook appears and swings across the room carrying Bomblings for Link to use to stun Diababa's middle head, leaving its eye open for Link to attack with his Sword. Upon recovering, Diababa sprays poison at Link, so he must dodge it. The two smaller heads also continue to attack occasionally. Link can choose to defeat them, however, they can eventually regenerate. Link must repeat this process until Diababa is defeated.

Upon Diababa's defeat, Link receives the first of the three Fused Shadows and a Heart Container.

Trivia

 * When defeated, Diababa, along with Blizzeta, share a different "Boss Clear Fanfare" in comparison to the other bosses in.
 * If Link descends into the water pool where Diababa was, he will fade back to the entrance of the boss room.

Nomenclature
