Deku Baba
Ocarina of Time
Deku Babas appear mostly throughout the Forest Temple, Kokiri Forest and Inside the Deku Tree. Their appearance is very similar to other Zelda games. They only reveal themselves when Link gets close to them, as in other Zelda games. Their attack method is to lunge at Link, which can easily be blocked by using Link's shield, or by simply backing away.If the Deku Baba attacks you, they will trap you in their mouth and continue to due small damage until they release you. If you kill Deku Babas when they are lunging out to attack you, you will obtain deku nuts, if you kill them when they are in their regular position, you will obtain Deku Sticks.
Majora's Mask
The Deku Baba is a species of carnivorous plant famous for their short temper, feisty attitude, and their production of Deku Sticks and Deku Nuts upon defeat. A Deku Nut is the bud of the Baba, while a Deku Stick is the stalk. Deku Babas thrive in forested areas where other Deku species, such as Deku Scrubs and Deku Trees, usually preside. As such, the best place to find one is in the Swamp at woodfall.Deku Babas rarely exist alone, and it is very common to find a thriving patch of them in heavily forested areas.
Twilight Princess
In Twilight Princess there are three variations of Deku Babas. The regular one's that come out of a tiny patch of grass and try to attack link when he gets to close. The second type are called Baba Serpent, these have 2 stages before they die. First Link needs to cut there Stem, they then slither along the ground. Link must now attack them or they will grab a hold of Link and the only way to get out of the grip is to do a spin attack. The last type is called Big Baba. These varieties are defeated by trowing a bomb into the flower part they grow out from. The Big Baba is only fought twice. Once in the Forest Temple and once in the City of the Sky.
Skyward Sword
Blue Variation
Deku Babas greatly resemble their appearance from previous Zelda titles. They come out from underground and try to bite Link if he gets too close. A new feature is that when battling the Deku Babas, Link must slash in the direction that the enemy's mouth is open. Some Deku Babas need to be sliced vertically while others need to be sliced horizontally. Alternatively, Link can toss or roll a bomb towards a Deku Baba and it will gobble it up before exploding within its mouth.
Some Deku Babas can be seen hanging from walls or the ceiling and they are out of reach from Link's sword. In order to defeat these fellows, Link must use the beetle. After sending out the beetle, Link can track its direction so that it cuts down the deku babas from their stems, causing them to fall to the floor in defeat. Link can also use his bow and arrow to cut these deku babas from their stem.
Gold Variation
The Golden Deku Baba is a stronger variation of the standard Deku Baba. It will attack Link in the same ways as a standard deku baba by lunging towards Link, attempting to bite him. Its mouth is divided into four parts, rather than the two halves that a standard deku baba will have. This will allow the golden baba to alternate directions in which its mouth opens, meaning Link will have to slash either horizontally or vertically, depending on how its mouth is open. Additionally, unlike standard deku babas, the golden babas take multiple hits to defeat and can be quite challenging.
