Diababa

Twiit Parasite: Diababa is the boss of the first dungeon, the Forest Temple, in The Legend of Zelda: Twilight Princess. The boss itself is made up of two large plant heads that resemble Deku Babas and one massive plant head with a hidden eye inside its mouth. The appearance hints Diababa may have originally been a Deku Baba which touched the Fused Shadow.

The beginning of the fight starts with only the two smaller heads (1). Bomblings can be seen around the field and your objective is to use the gale boomerang to make the bomb collide with each of the two heads. A single hit will defeat each one (2).

The second phase of the fight begins when the larger head enters the battle. Ook will swing across the room carrying the Bomblings for you to use (3-4). You must now target the Bomblings as they swing back and forth and then the large head of Diababa. Avoid getting hit by his poison spray and the usual attacks by either one of the smaller heads (5).A hit will stun the head temporarily and leave the eye open to damage (the Critical Point) (6). Attack it quickly with your sword. Immediately following, Diababa will spray poison at you, so you must move quickly to dodge it. Repeat the process until Diababa is defeated, but if your sword strikes are accurate you should not have to hit it with more than two Bomblings. If you accidentally grab a bombling, chances are a guard head will attack and you can feed it the bomb.
