Nintendo 1.13 manual

King Helmasaur is just like the little Helmasaurs you see all over the dungeons. But this one is the king! In the first part of the battle, you

need to break open the hard purple shell that's protecting him. Keep hitting it with the magic hammer. He moves forward and backward. Don't hit him when he's moving towards you or you'll get hurt. When his tail shakes around quickly, he's about to try whipping you, so get close to his face to avoid getting hurt. Occasionally, a fireball comes out of his mouth, splits into 3 pieces, and each of those pieces splits into four fireballs. Be careful to avoid that. It takes 17 hits to destroy his purple shell. After that, hit his face with the sword to hurt him. He moves around much faster now, and he's a lot harder to hit without getting hurt yourself. The attacks of fireballs and tail whips continue.

After breaking his helmet, it takes about 9 hits to defeat him. I'm not sure exactly, I lost count :P

Swamp Palace - ARRGHUS

The Arrghus is a huge eyeball-jellyfish creature surrounded by small spongy balls. In the first part of the battle, you need to destroy the sponges. Stand at a distance from him and use the hookshot to pull one of the sponges to you. Then slash away with the sword to destroy it. Every few seconds, the sponges will form a wider circle and spin around fast. Be sure to keep your distance. After you've destroyed all 13 sponges, it's time to destroy the Arrghus itself. Now that it's all alone, it leaps into the sky for a few seconds...then comes crashing down. It will try to land on you, so never stay in one place for more than a second. When it's bouncing around the room, hit it with the sword. Then it leaps into the air again and repeats the process. It takes 9 hits and he's completely defeated.

Skull Dungeon - MOTHULA

The Mothula is a big moth creature...but it's only half of the danger of the battle. You'll have so many obstacles and dangers around you that

it's hard to concentrate. The room's floor is moving in random directions, the spike traps are constantly moving across the room, the Mothula shoots fire thingys at you, and you'll also need to avoid the Mothula itself. I pray that you have fairies in your bottles, you'll need them! At first you should attack the Mothula with the fire rod, but

you're bound to run out of magic quickly. When you run out of magic power, just attack like crazy with the sword. The real challenge here is

avoiding the hordes of traps all around you. The spikes shake a bit before they move, but I doubt you'll even notice it since you're concentrating on the boss itself. There's not much more advice I can give you. May the force be with you.
