Ice Cavern
After the story sequence you'll be just outside the Fire Temple. Walk
back over the bridge (use your Hookshot to cross where's it's broken)
but instead of going out the cave, walk over the next bridge to a cave
blocked off by red boulders. Use your hammer to mash the boulders and go
inside to the 4th Great Fairy who will double your magic meter. Now you
can either walk down Death Mountain or you can use the Prelude of Light
to warp to the Temple of Time, walk outside, and summon Epona with
Epona's Song. Either way, head on over to Zora's River. Make your way up
the river just like the last time and just like the last time, play
Zelda's Lullaby on the Triforce symbol in front of the water fall.
Unlike last time, however, you'll find that the water world is now an
ice world.
Go up to the King's room and go around behind him to enter Zora's
Fountain. Now hop on the ice blocks and make your way to a cave there
known as the Ice Cavern. The Ice Cavern is a fairly straight forward
level. Just make sure you have a couple of bottles to use to store the
magic blue fire in. You'll need at least two to carry back out with you
- one for the King and one for the Zora store. Now, from the entrance of
the Ice Cavern, follow the path until you reach a room with a revolving
spike thing and some ice statue guys. Kill the ice statue guys to open
the door to the next corridor. At the end of this corridor you'll be in
a room with a big helicopter-blade thing made of ice. You'll have to run
around and collect all the silver rupees to open the blocked door. One
of them is right next to the exit door floating in the air. Go through
the door and tunnel and fight your way through the next room until you
get to a room with some ice bridges everywhere. Go up on the ice bridges
and get to that blue fire. Now use all your empty bottles on that blue
fire to collect it for future use. Use one of them to melt the red ice
around the treasure box at the end of the bridge to get the dungeon map.
Make sure to refill it (you need two bottles at least BTW), and go back
to the helicopter blade room.
There are two additional exits from this room that are covered with red
ice. Use your bottles of blue fire to melt them. Go through the one to
the East (the one with two pots next to it). It leads to a small round
room containing another blue fire thing. Refill your bottles and use
them to melt a heart container piece and a treasure box containing the
compass. Now refill them again and go back to the helicopter blade room
and then through the West exit. The basic idea behind this next room is
to push that block of ice around and use it to get where you want. The
following directions pertain to the direction you were facing when you
first walked in. First, push it left and get the silver rupee there.
Then forward and get that one. Then (careful not to fall of the edge!)
push it right, then back toward the entrance to get another silver rupee
there. Then push it off of one of the edges and a new one will appear.
Push this one forward then right and climb up to melt the last silver
rupee with your blue fire. Then push this one off the edge to get
another new block. Push this one left, forward, right, back, and then
left to get to the exit and go through it.
You'll have to use some blue fire to melt some red ice in your way in
this corridor. Open the ice door and you'll face an ice wolf. Kill it
and receive the Iron Boots. Sheik will come and teach you the Serenade
of Water. Use your new Iron Boots to sink into the water behind the
treasure chest and walk to the end of the passage. Take the boots off
once you emerge from the water. You're now back in the first room.
Before leaving the ice cavern, go back to the small round room where you
got the heart container piece and the compass (East of the helicopter
blade room) and fill two bottles with fire. Then go back out the way you
came in. Leave Zora's fountain and use a blue fire on the frozen King
Zora. Talk to him and he'll give you the Zora Tunic, which keeps you
from drowning. Go down and use your other blue fire on the doorway to
the Zora Store. Now play your Serenade of Water and you'll warp to Lake
Hylia. Run forward and jump into the water in front of you. Make sure
you're wearing Zora's Tunic and then turn around and equip the Iron
Boots. Use your Hookshot to hit the blue diamond above the doorway and
it will open. Go inside and you're now in the Water Temple so take off
those Iron Boots.
