It's time for the third boss of the game, Barinade. To start off, it has a bunch of electrified Bari surrounding its body, and it is connecting to the ceiling. It can fire off electricity at Link, which is easily sidestepped.Take out your Boomerang and throw them at the tentacles connected to the ceiling. Once these three connections are severed, it will start spinning the Bari around itself and chase after you.
This is your opportunity to throw the Boomerang at its main body, which when hit, will stun it. You should kill the Bari with the Boomerang when the main body is stunned, throwing the Boomerang at the main body from time to time to keep it stunned. With all the Bari gone, Barinade will shoot electricity at you while spinning around the room. Stun it again, hitting it with two Jump Attacks, which will prompt it to shoot electricity and start spinning again. Keep doing this until the boss is defeated (it has 10 health). Grab the Heart Container and then step into the blue light to be transported back to Zora's Fountain.
