It was a long way which involved a LOT of digging, but eventually the Earth Skylanders were able to reach Stonetown. However, they needed to get through a Cyclops outpost to get to the town. And for some reason, the ground was shaking! "This place must be named Stonetown due to all the earthquakes they have here." Terrafin said. After a long trek through the outpost, the four of them reached the town. But then, they noticed something else. A huge Stone Golem was on the rampage! "That thing must be after the Eternal Earth Source!" Terrafin said. "It's not looking for the Eternal Earth Source." A terrified Mabu yelled as he ran by. "It IS the Eternal Earth Source! AHHHHHHH!" Quickly, the four ran towards the golem, who was ready to fight them! "GGGGGRRRRRRRRRAAAAAAAAHHHHHHHH!" It roared, stomping furiously and causing another earthquake. After using their powers to create a stone bridge from the nearby floating rocks to get to Rumbling Ravine, the Earth Skylanders were ready for battle! With his bulky strength, Terrafin was able to catch a boulder the golem threw at him and destroyed it with an uppercut. He and Bash got up close and personal to attack, but the golem stomped on them. Bash quickly rolled out of the way while Terrafin burrowed to dodge the foot. Bash then whacked another boulder back at the golem with his tail while Terrafin summoned mini-sharks. As Bash summoned a stone projection that he whacked, Dino-Rang was doing some summoning of his own by luring the golem into Stonefist Traps. He then threw his Stone Boomerangs at the golem, then used his Boomerang Shield technique to block small rocks. Prism Break summoned a crystal and then fired his laser at it, thus refracting the beam. When it did no damage to the golem, Prism Break used his Crystal Eruption to shatter the crystal, sending fragments at the golem. Terrafin also belly-flopped onto a smaller boulder before it could hit Bash. The golem then summoned a wind vortex around himself and conjured more boulders, while the Skylanders dodged them. After the golem failed to smash them with his bare rocky fists, he then threw a bigger boulder at them! Terrafin took cover behind a rock, which the boulder bounced off! It hit the Golem, weakening it. But however, it would not go down without a fight! Suddenly, the golem got weaker and weaker until it exploded into hundreds of rocks! And among that pile of rocks, was the Eternal Earth Source itself. Terrafin grabbed it, and the team headed back to the Ruins.
"Skylanders!" Eon said. "I see that you have gained the Eternal Earth Source! It is the eye within the eye, and the foundation of all Skylands!" "Hang on a sec, I thought Magic was the foundation of all Skylands! Meh, whatever." Terrafin put the Earth Source close to the Core, where it flew into the Crystal Eye. The eye then pointed upwards, while the pillar fell to reveal the Core's inner workings. Then, a laser shot out of the eye and into the air! "Woah. That was easy!" Gill said, amazed. "Do not rest yet." Eon warned. "Just because the Core of Light has activated its beacon doesn't mean the Darkness is gone. The beacon is very weak. We need the rest of the Eternal Sources to strengthen it." Then, the Life Skylanders noticed the nearby flower patch rising! Instinctively, Stealth Elf readied her daggers. Stealth Elf was an elf ninja who had been separated from her parents when she was very young and had awoken in a hollow tree with no idea about how she got there. She was then taken in by a tree creature that wielded a green sword and specialized in the arts of Ninjutsu. Stump Smash was a tree creature whose arms were turned into stumps via troll loggers. He used his stumps to smash every bad guy in sight! Zook was from a race of bamboo people who used his bamboo stick for multiple purposes, mostly a bazooka. Camo was a dragon-plant hybrid who harnessed solar energy to make foods grow at a highly accelerated rate, making them explode! "Ahhhh!" The plant creature said. "Sunlight feels so good on my leaves! And the water! So delicious! And the earth is just right! Thank you for reviving me!" "Who are you, and what are you doing here?" Stealth Elf said, not letting her guard down. "I am Arbo!" The creature replied. "Son of Barbo! Child of Larbo! Spawn of-." "Yeah, yeah, yeah, we get it!" Stump Smash roared. "Now, can you help us?" "I don't know!" Arbo said. "I'm only 8 seconds old after all. But somehow, I seem to have memories of all this happening before! We need to find the Eternal Life Source, but to do that, we must find the Seeds of Life and plant them so that their roots can point the way!" "Uh, how did you know-?" "I can do something. Like this!" Using his powers, Arbo was able to summon a giant vine! "WOAH!" Camo said, astounded. "How did you do that?!" "I don't even know!" Arbo replied. "Huh. It leads up to Treetop Terrace." Zook said, looking up as far as he can without climbing the humongous vine. "But I believe that the locals there call it the Tree of Life. The Life Seeds must be there!" And with that, Arbo took the Life Skylanders to the Tree of Life.
