You will find yourself in the sealed grounds. Once you regain control make your way downwards, fighting a couple of Deku Baba's on the way.
Location: Faron Woods, Skyview Temple, Lanayru Desert
Attacks: Venomous Bite
Effective Weapon(s): Sword, Beetle, Bombs, Bow
Strategy: Deku Babas don't have any eyes, but that doesn't mean they can't track you with... wait, they don't have any sense of smell or sound, either. Be careful not to let them bite you. Their buds are covered in a hard carapace, so if you want to cut them you'll have to slice them across their open mouths. Gold-colored ones are tougher and can open their mouths in multiple directions, so watch them carefully. The Beetle can also slice right through their stems, and they'll gobble down any Bomb Flowers you toss their way...
The door is currently useless to you, so make your way down to the center of the Sealed Grounds. As instructed, hit the pillar with the charged beam. You will now be able to dowse. Searching for Zelda will point you to the previous sealed door. The journey up is quick, use the newly formed jetstreams. The door leads to the Sealed Temple, in which you wil be takling to an old woman (man?). Now you will have the ability to place beacons. Once you regain control, note that there's save statue on the opposite side of the door that you need to go through. There's also a chest in the corner containing a Revitalizing Potion.
Functions: Fully reverses damage to your equipped shield and restores up to four of your hearts
Upgrades: Revitalizing Potion+
How to obtain: Found alongside Empty Bottle 2; purchase from the Potion Shop for 50 Rupees.
Description: The Revitalizing Potion serves a dual-purpose. Not only does it replenish four units of your life meter, it also fully repairs your equipped shield's Shield Gauge!
Exit through the east door, and head towards your newly placed beacon. Just a few steps ahead you'll run into Gorko the Goron being assaulted by a bunch of Bokoblins.
Location: The Surface
Varieties: Red, Green, Blue, Archer
Effective Weapon(s): Sword, Bombs, Bow
Strategy: Bokoblins are more intelligent than your average monsters. They'll use their weapons to block your attacks, sometimes parrying your incoming blows. To defeat them, you'll have to strike from a direction they're not defending against. They are known to wield a variety of weapons, from rusty cleavers to clubs and hammers. Boss Bokoblins carry horns that they use to summon reinforcements. You'll have to take them out by detonating their watchtowers with Bombs to prevent them from calling in backup. They seem to appear in multiple color varieties as well.
Taking care of them is easy enough, and once you do so, Gorko will share some rather hillarious information with you. Before you move on towards the beacon, go up the vines and through the tunnel. Push the log down - this'll create a shortcut for future use. You'll have to push another one before you reach the entrance to Faron Woods.
One vine swing and a couple of steps into Faron Woods and you have to save yet another character from Bokoblins. What would these people do without you?
Obviously enough, you follow the Kikwi up the ledge. Use your dowsing ability to look for it. It'll hide behind two mushrooms (Slash at them to scare it away), and eventually behind a tree.
After you're done talking, turn around and push the log down. This'll create a shortcut to the area below and earn you your first Amber Relic!
Head east and up the slop with the Deku Baba on it. Keep following the path - along the way you'll have another log to push down and another Amber Relic to pick up. The path will lead you to a cliff overseeing a lake. Cut the rope and use it to swing to the other platform where the Kikwi Elder awaits. He'll ask you to find three missing Kikwis before "he can remember" information about Zelda. Very convenient.
Head through the small opening to the right and up the vines. Use your Wii Remote to balance when crossing the rope. Drop down and fend off another pack of Bokoblins. The first Kikwi is sitting up on a tree. Roll into it in classic Zelda fashion to shake him off. Brutal, but effective. In order to get out of that area, and continue your search for the Kikwi's, you'll have to climb the vine that dropped down with the Kikwi and swing yourself to the nearby ledge. Note that you don't have to climb the rope up high, two steps is enough. Once you're on the other side, leap down.
Location: Faron Woods
Attacks: Peck, Bird Bomb
Effective Weapon(s): Sword, Slingshot
Strategy: Guay will dive-bomb you and peck away, just as annoying as the Keese, but they also have an extra ability: they can lay droppings on your head. These potent heaps of nasty will slowly drain health as you choke in an effort to breathe in the noxious fumes.
Head west, towards the elevated area right next to the bird statue on your map. You can climb up the darkened part. Head left and cross the rope to land your very first Heart Piece! Head into the opposite direction, past the Deku Baba and onto the elevated area. There's a hole obscure by the grass at the far end - drop down. Follow the path left into another small area, where you'll find the second Kikwi underneath a bush.
Location: Faron Woods, The Sky
Varieties: Grass, Rock
Attacks: Spit Rocks
Effective Weapon(s): Shield
Strategy: Octoroks attack you both on land and in the sky. Sky Octoroks latch onto floating islands and try to shoot you from your bird, while land-bound varieties disguise themselves as bushes and burrow in holes in the grounds to hide. Using a Shield Bash to repel their rocks back at them will defeat them.
You'll have to drop down and go around again now, head towards the northern-most region of the map, crawling through the small opening in the tree's branch. Get rid of the two Bokoblins and climb the small elevated part to your left. Dash up the wall to grab the wines and make your way up. Use the Wiimote flick to leap and get across gaps, and make sure to pick up the Stamina Fruit on your way. Once the ledge, cut all the grass so that the Kikwi can't hide anywhere, then talk to it. Now all you gotta do is make your way back to the Elder.
Type: Evolved Carnivorous Plantform
Location: Faron Woods, Skyview Temple
Attacks: Deku Bite
Effective Weapon(s): Sword, Bombs, Bow
Strategy: This gold colored Deku Baba is more durable than its blue cousin and also possesses the ability to open its mouth in multiple directions. Pay close attention to these dynamic changes as you fight. It's still got all the other vulnerabilities, too...
As a reward for finding all the Kikwi, you'll receive "a precious Kikwi heirloom".
Functions: Fire weak short-range projectiles
How to obtain: The Kikwi elder, Bucha, gives you this Slingshot to use against monsters as you hunt down the missing Kikwi.
Description: This Slingshot looks like a kid's toy, but it can stun enemies and even take out some small fry such as Keese. Its seeds don't fly very far, but they're strong enough to strike certain switches.
Next up, the journey to Skyview Temple! Go to the temple ruins in the east using the vine shortcut that the Kikwi Elder has shown you just now. Inside you'll find a flight of stairs leading to the top, where you'll find a save statue. Use the slignshot to drop down the vine nearby and swing across.
Once inside the Deep Woods, you can go straight to Skyview Temple, or you can turn left, towards the lone tree. There's a hornet nest hanging from it, and you roll into the tree to make it drop down, landing you a Hornet Larvae, an item used for crafting.
It'll also make the hornets angry. Just sayin'.
One you actually go towards the temple, you'll reach a rope not unlike the ones you crossed before. However, before attempting to go to the other side, use your slignshot to drop down the hornet nest above it, otherwise your attempt will be very short lived. Once you're over, go left and push down the log at the end of the path, creating an easier path.
Go back and follow the actual new path now. As soon as you can, turn right and across the ledge. The rop here is going to be covered in sticky bombs, and a Bokoblin will attempt to get to you via the rope as well. Just keep flicking your Wii Remote forward as you balance to shake them all off the rope. Climb up to the statue and jump back to the other side using the vine. Go to Gorko and talk to him, and to find your first Goddess Cube!
Push down yet another log, and walk another few meters to find... well... your SECOND Goddess Cube! Hooray!
At the entrance to the temple, pull out your slingshot and shoot the crystal switch above the door.
