Hyrens Locations
There are two areas where you can get one out of four or all of them.
For the Leaf and Timber Hyrens, go through the first Shadow Gyser. When you get to the underneath, play a few rounds of that Brub game. Beat the second Gyser and you will be captured. Go to the Cald city and save them.
You will now have to get the Orothe Boots. Go talk to the bridge builder.
Find a Lava Arboll and take it to the bridge builder. When you have the boots, go to the man in front of the cabin. He will tell you how to get back to the Cald. When you get back, you will not be in the Cald but by the Old Lady's house. Talk to her. When you are finished, go to Naroom and a ticket store will be opened next to the ring shop. Buy a blast item and take it to the underneath tunnel.
Go past the rock in front of you. Turn left the first chance you get, to find more rocks. Break them, go down the stairs, and use your blast item to blow up the wall where you find the cracks. Follow the path all the way to a forest and enter it. Here you will find the first two Hyrens, Timber and Leaf. They are difficult to defeat.
For the Cave and Mushroom, go from the forest that has Leaf and Timber Hyrens and move straight down through an opening. Jump across the lava and go out of the cave. Go to the left where the brigd builder is located, but do not go to him.
Go back to where you found the Lava Arboll and walk around. You should discover a bridge that has stairs around it. Go down one and wait for a spinning white object. When you see the object, run into it and you will find yourself underneath. Here, you will find the other two Hyrens, Cave and Mushroom.
