Barinade

Bio-electric Anemone: Barinade is the third boss in Ocarina of Time, residing Inside Jabu-Jabu's Belly. He is the guardian of the third Spiritual Stone, Zora's Sapphire.

At the start of the battle, Barinade is attached to the ceiling of the arena, sucking life energy from Lord Jabu-Jabu. He must be separated from the guardian deity by severing the three tentacles that attach Barinade to the ceiling, using the boomerang. While doing this, Link must watch out for Barinade's ability to shoot lightning from its other three tentacles.

Once separated, Barinade is surrounded by a group of electrified jellyfish, preventing any direct attack on its soft body. Getting rid of them will be Link's second task. This can be done with the boomerang when Barinade sends them out to attack.

Once all of the jellyfish are gone, Barinade will start to spin wildly through the room and firing blasts of electricity at Link. There are more jellyfish that protect him while he is spinning. Again, they can be destroyed with the boomerang to get a clear hit on Barinade's body. Once Barinade is exposed, Link can use the boomerang to stun him and then attack using the Kokiri Sword or Deku Sticks. After several strikes, Barinade falls (and blows up in a rather grotesque manner).

After getting rid of this foe, Link will be rewarded with a Heart Container and the third Spiritual Stone.

Trivia
The fighting style of Kalle Demos, the parasitic plant-monster from The Wind Waker, is reminiscent of Barinade.
