Getting into the Forest:

Now that you've rescued the elemental warrior known as Rubble from the shadow troll of the realm, you're now able to enter the Forgotten Forest. Head back to the forest glade, and near the middle of it, you'll find four, one-eyed trees surrounding a small platform. Step onto the platform with Rubble, hold onto the back, right button until Rubble shoots all of his rock pieces off of his body, where they will hit the trees' eyes, thereby opening the entrance to the Forgotten Forest beyond the river across the four trees; the entrance looks like an enormous tree with yellow eyes.

The Forest:

As you enter this long-forgotten forest, you'll be started out with a short cutscene where Kalus is taking Kameo's uncle Halis into the the forest temple, where a deadly creature awaits for your arrival. Once the cutscene has ended, walk forward and into the only passageway so far. Once you have, the entryway that you walked into will close right behind you. As you can see, one of the local, plant creatures of the forest is being held captive by Thorn's mischievous trolls. The trolls guarding the cage will have shields, so press the back, left button with Rubble, shooting a rock behind them, when the rock comes back to you(remember not to move when you it the rock behind the troll), it will damge the trolls. Continue this technique until the two trolls are no more. Infront of the imprisoned villager's cage, you'll see a large pad. Stand onto the pad and transform into the Rubble. Doing so, the mouth of a stone beast will open above the cage. When the mouth opens, press the back, left button with Rubble and shoot a rock into the stone beast's mouth, thereby opening the cage and freeing the young villager. The villager will reward you by playing his fluit, which brings a plant from behind you alive. As you can see, the plant has shot out a strange, plant-looking shell. Form into Pummelweed. Hold onto the two, back buttons as Pummelweed uses his uprooter technique. While using this, have Pummelweed spin under the shell. While he's under it, move it towards the wooden fence ahead. Once the shell touches it, the fence will explode, leaving another passageway open for you. Walk through the newly-opened passageway, where you'll encounter two Golumn-looking trolls. The two trolls will dive under an explosive shell, where they will be able to charge after you. Keep dodging their incoming attacks until one of the shells stop moving and their spikes are down. Transform into Pummelweed and use your uprooter attack, punching the shell into the air. With the troll exposed, quickly destroy it with Pummelweed's punching technique(s). Do the same to the other troll, and another passageway will be opened ahead. Walk through this passageway, where you'll find a couple of troll archers. The easiest way in killing them is using Rubble and shooting rocks at them from a not-too-far of a distance. Once the archers are destroyed, head over to the pad infront of another imprisoned villager. Use the same technique as before and "high-shoot" a rock into the stone creature's mouth. Once the young villager is free, he'll begin to play his own fluit, shooting another explosive shell out of a plant. Now, head back to the same area where you fought the two, skinny-looking trolls, where you'll find another explosive shell. Use Pummelweed's uprooter technique and go under it. Once you're under it, head forward and destroy the nearby fence with the shell. Also, you may wanna destroy the two trolls infront of the fence aftward. Once you've done that, head through the now-destroyed fence where you'll find three more shielded trolls. Use Rubble and "high-shoot" a few rocks into the air and behind the three of them. As it comes back to you, it will damage the troll. Keep on doing that until the three trolls are down. Once they're destroyed, walk through the rest of this small passageway, where it will then close behind you(then again, there's really no other reason to go back, is there. Hehe..). In this next location, you'll find more shielded trolls. Destroy with Rubble using the same technique as before, and you'll see a nearby blockade in the bottom, left corner of the area go down. Head through it, where you'll find more trolls. Keep walking forward, destroying every troll in your path until you see another passageway leading downward. Head down, where you'll find more troll archers. Take them out with Rubble at a slightly far distance. After the archers are down, use the same technique with Rubble and free the next villager in the same area. The villager will play his fluit, releasing another explosive shell in the same area in which you fought the last set of shielded trolls. Head back towards the hill and walk back up. Unfortunately, the entryway to the explosive shell is closed, and you'll find yourself trapped. You'll also find three more, skinny, Golumn-looking trolls, who will hide under their own shells. Use Pummelweed's uprooter and take 'em down. Once they're out, you'll be able to head back towards the explosive shell. However, once you're there, you'll find an enormous ogre and several trolls to keep you company. Destroy them to keep them out of your way(I suggest using Pummelweed on the ogre). Once the ogre and the couple of trolls are gone, use Pummelweeds uprooter, head under the explosive shell and head forward towards yet another fence. Once the shell has touched the fence, it, along with the shell will be destroyed. Head through the newly-opened passageway, where you'll find two trolls holding two shields on each of their hands. Take out the metal shields with either one of the two warriors and then kill the two of them. You'll then find two more archers hiding behind two seperate boxes. Take them out with Rubble from a distance. Once they're no more, another passageway near the back of this area will open. Head through it, where you'll find two more trolls. Take them out, head to the left, where the entrance to the Forest Temple lies. However, you'll have to take out a number of trolls to get in. Once they're all down(using Rubble on the shielded ones), head through the temple's entrance, where your uncle Halis will be waiting for his rescue.

The Forest Temple:

Once you've entered the temple, you'll see a number of blue mosquitoes coming towards you. They're no really trouble, but if you want, take them out with Rubble. Once you're at the end of the short hallway, use Pummelweed's uprooter and head down the vine blockade. Now, head to your left, and head up a stone set of stairs. Head to the left again, and use Pummelweed's uprooter to pass another vine blockade. Inside of the chamber ahead, you'll find another stone creature. Stand on the pad infront of it with Rubble and when the mouth of it is open, shoot Rubble's rocks into it, activating two lifts outside of the chamber. Head back outside with Pummelweed's uprooter and through the same blockade as before. Stand on the nearby lift with Rubble(near the two villagers). Now, at the top of the lifts you'll find another stone creature. Shoot a rock into the beasts' mouths, and you'll see that inbetween the two lifts, a set of stairs will be activated. You may wanna use Kameo to jump your way to the top of the stairs. Once you have reached the top, head through the bright passageway, where Kameo's uncle Halis is being held captive.....
