Didn't update sooner because I was working on this long chapter.

Ooo,

Meanwhile, back in Ooo, Marceline was still wondering if Finn was doing okay. She knew where they went from information that Princess Bubblegum told her and she did secretly wish that she also gave her a dimension traveling device. She did remember when those strange skeleton-like creatures attacked her but mysteriously teleported away which she also found out that they were ordered to return by their master. But still, she felt glad that while Finn and Jake were off finding the Gems of Light scattered in the other three dimensions, she and several others were on a search for the Gem of Light in their dimension and it was easier how Bubblegum gave her a device that could track down large amounts of energy but felt disappointed that they were far from it.

Equestria,

Gilda the griffon was flying through the skies looking at the land below her and soaring high. She did remember her falling out with Rainbow Dash when she called Rainbow Dash's friends lame and insulted some of them and left. And she didn't regret that very much. At the moment, while she was flying, she saw several strange creatures behind her that she never saw before. They had eight red eyes and four bat wings and were shooting something at her. She avoided them and smashed through them taunting, "Ha! Is this the best you've got?" But just as she said that, several Changelings and two large figures that resembled dragons only they had long bodies and eight red eyes came. "Oh great," she said, looking at her enemies. The Changelings and the dragons chased after her very fast. Despite the fastest that she could fly, they were gaining up and what else was slowing her down was that she had to constantly dodge what they fired at her and some hit her. She kept on flying until she saw one of the dragons slip down and come in front of her and grab her and everything went dark.

When she opened her eyes, everything was blurry and she saw two figures in front of her. One of them had the same colors of the Changelings but looked more like a tall horse and the other looked like a snake except that it had a round head and red eyes and arms. "Who are you guys?" she asked. "Who I am is not important," said the snake-like figure. "What is important is that I want to employ you for our cause," it said. "Whatever you want, I'm not joining!" she shouted at it. "You have no choice," it said. "Ha! Make me!" she taunted it and tried to make a run for it but was pinned down very quickly and found herself all coiled up and was looking up into the creature's eyes on its snake head. She tried not to look but could not take her eyes of the creature's red eyes. After a while, hypnotic swirls appeared in her eyes as she looked into its eyes and then she was fully hypnotized.

"Glad that's done," said General Serpentius after hypnotizing Gilda. "Are you sure it will work?" asked Queen Chrysalis. "I have a backup plan for that," said General Serpentius, "For I have sent a frightening mechbeast to their present location in case our little friend fails," he said. "That's great," she said. "Enough of that," said Serpentius, "Let's go find the dark energy source that our master told us," he said.

Meanwhile, Finn, Jake, Spike, Twilight Sparkle, Rainbow Dash, Rarity, Fluttershy, Applejack, and Pinkie Pie were heading toward the Everfree. "I wonder how Flame Princess is doing," said Finn as he was walking. "Who's Flame Princess?" asked Rainbow Dash. "A friend at home," said Finn, "And I miss her," he said. "But it isn't the time to be nostalgic," he said, "We've got Gems to find." "Wait," said Twilight, "If there were four Gems of Light and one for each dimension then what about the one in yours?" she asked. "It's not a problem now," said Finn, "And Princess Bubblegum has taken care of it," said Finn. At the moment, Lorina suddenly appeared on the disk. "So where in the Everfree Forest is it?" asked Finn. "It's on the edges of it and it's very dark there," she said, "And it could be a great hiding place for Kronosians, specifically mechbeasts," Lorina said in a warning tone. "I'm scared," said Fluttershy.

As the nine were walking into the dark forest, they all got dashed by something. "What was that!" shouted Finn. But he only heard an animalistic sound. Then to the surprise of the nine, a griffon with red eyes and a brown body walked out, snarling. "Gilda?" said Rainbow Dash in surprise. "You know her?" asked Finn. "Old friend," she said. At the moment, Gilda leapt to attack her. Rainbow Dash narrowly avoided the griffon's sharp talons and got to the ground. "Yah!" shouted Finn as he leapt at the griffon but she avoided and struck him with her lion tail. Jake stretched into a large form and pinned down Gilda, only for her to bite him. "Yeow!" yelled Jake in pain. As Finn got up again, Lorina appeared and said, "According to my energy detections, this creature has been mind controlled by a Kronosian." "What should we do then?" asked Twilight. "If we can defeat her, then the mind control spell will wear off. Then, Rarity and Twilight levitated some rocks to hit her; Spike blasted some fire at her, Fluttershy threw some twigs and Pinkie Pie blasted her with a party cannon. Gilda dodged them but not all. Reeling from the blasts, she crawled and gave a loud shriek. As she was preparing to attack again, she found herself in a magic field, and saw it was originating from Twilight Sparkle. She clawed, thrashed and attempted to break off from it but it was no avail. Twilight chanted a spell and a few moments later, the red in her eyes disappeared and was back to normal.

"Where am I?" she asked in surprise. "The Everfree," said Rainbow Dash. "You guys again," she said looking at the six ponies and dragon. Then she turned and saw Finn and Jake, "What are these guys?" she asked. "Some new friends," said Rainbow Dash. "Whatever," she said, "I don't care what you and your lame friends are doing now and I've got my own stuff to do," she said and flew off. "That was quick," said Jake. "Anyways," said Finn, "Let's continue on the quest," and the nine of them all continued to walk into the Everfree, unaware of the creature that was following them.

It was very dark for Finn and he the forests were very dense. "The Gem isn't very far from here," said Lorina. "That's good news," said Finn, "Now, let's split up so it will be harder for the Kronosians to track us down," he said. "Good plan," said Twilight, "But where will we meet?" she asked. "Show the map, Lorina," said Finn. Lorina created a digital map that showed their present location and the location of the Gem. "We shall meet each other there," said Finn, pointing to the place close to the Gem location. The ponies were a little uneasy about it. "But it's scary," said Fluttershy. "I agree," said Spike. "It's the Gem that's matters not your fears," said Finn. "And let's start," the nine all split up and walked different paths while a creature lurked in the bushes, looking at its targets.

Finn walked and walked and didn't very scared but had a tiny tinge of fear but brushed it away. He remembered what Lorina said earlier about a mechbeast and he had his sword out at all times. As he continued to go, he heard a rustle of branches and turned but nothing was there and continued on. It wasn't that dark in the forest but still, there could be danger lurking in every corner. As he walked into a corner in the forest, he spotted a figure, and it was getting closer. Upon closer examination, Finn saw it had a blank grey face, had a faint red glow and a dark suit. As that creature walked closer, some tentacles seemed to reach from its back. Finn ran to land a hit on it only for the creature to expand and swallow him and there was darkness.

Fluttershy was feeling uneasy as she was walking through. She had been to the Everfree before but not this part of the Everfree which she was unfamiliar with. At the moment, she heard a rustle and a branch breaking. "Who's there?" she asked in a scared voice as she turned back but there was nothing. Giving a sigh of relief, she continued on. She did know the location that they would meet and she ran a bit to go faster. She heard another rustling sound and some static and felt more frightened and ran faster. She tried to take off and fly fast but knew that she wasn't as fast as Rainbow Dash and after a while, fell down, panting. She felt more static and looked up at her attacker and screamed as it enveloped her.

Spike was getting a bit nervous in this part of the Everfree and it was darker than the rest. He continued to walk and walk and after a while, just when he thought that nothing was going to happen to him, he felt static and looked to see a tall, slender figure emerge from the bushes with tentacles and envelop him and screamed as he got enveloped.

Meanwhile, Twilight was trotting toward the rendezvous point and heard a loud scream and felt a little uneasy. She kept on walking and walking. Then, she heard a rustle of leaves and footsteps then static and she didn't dare to look behind her and continued walking and just when she turned around, the static got louder and a tall, slender, blank-faced figure was in front of her and it enveloped her and then she could see nothing but darkness.

Rarity like Twilight, was also feeling a bit uneasy about this part of the Everfree forest. She walked but then felt static and heard footsteps behind her and when she turned, she saw a strange looking figure that then sprouted tentacles behind its back. She turned to run but it already caught her and she screamed before she was dragged into it.

Pinkie Pie was usually cheerful although she felt a tinge of fear and walked. She walked until she felt static and turned around to see a tall slender creature and before she could even shout, it enveloped her.

Applejack was walking through the forest, observing her surroundings for danger and just when she decided that there wasn't anything chasing her, she realized that there was something following her. "So much for someone not following you," she thought to herself. She turned and looked at what her pursuer was and ran but tripped over a root and looked up at her pursuer to see what it looked like. Just before she got enveloped by it, the last she saw was a blank-faced figure wearing black with tentacles.

Jake walked and walked and suddenly, he felt static and heard footsteps and a rustle of bushes. "Who's there?" he said as he turned around but there wasn't anyone there. "Maybe it was my imagination," he thought as he turned back only to find a tall slender figure wearing black standing in front of him and it enveloped him quickly before he could do anything.

Rainbow Dash was flying fast through the forests and noticed that the trees looked a bit strange and that was one thing that made it different from the part of the Everfree she had been too. At the moment, she felt static and footsteps and looked behind to see a tall, slender figure wearing black but had a completely blank face and tentacles stretched from it and it seemed to be reaching for her. Thinking fast, she flew very quickly and it also followed. The two chased and chased and chased until Rainbow Dash got into a clearing and it came in to. Rainbow Dash backed up against a tree and the creature emerging from the darkness came closer and closer and closer. Just at the moment, when it reached sunlight, it seemed to reel in agony and clutch its body in pain and then a huge hole opened in its body and it vomited through the hole and out came Finn, Jake, Twilight Sparkle, Spike, Fluttershy, Applejack, and Pinkie Pie.

"What in the hay happened?" asked Rainbow Dash. "We were eaten by that thing, but we somehow got out," said Twilight Sparkle. "Where am I," said Finn gaining conscious, but just as he saw that figure, he snapped into action and charged at it and stabbed it through with his sword before it could recover from vomiting them all out.

It fell to the ground and lay there lifelessly. Then, its body disintegrated into nothing. "Glad that's over with," said Applejack.

Note: I suppose that everyone knows that the mechbeast in this chapter was an Expy of Slenderman, right? Other than the fact that it got stunned by sunlight.
