How do you beat Dongoron in Zelda Phantom Hourglass?

Answer 1

Make sure you are Gongoron and make him roll around the boss, when the boss roars loudly, carry on rolling until it runs into a wall then hit it, switch to Link and use a Bombchu and send it into the beasts mouth, switch to Gongoron and do what you did before but watch out for Link because those little things come after him so you have to switch to Link when monsters are near him, after fending them off switch to Gongoron and knock Dongorongo over and use Link's Bombchus to kill him After Gongoron has left and Dongorongo wakes up, run around the beaast until it breaths in and quickly throw a bomb in and when he falls over stab the odd blue thing sticking out of his back, when he dies run in to the room to win the Crimsonine
