I'd like to say thank you to EchoKazul and Raphaelfangirl4real for giving me some tips on how to structure the story. I hope this is better. Enjoy!

Raph was about to ask Leo if he was delusional, but then he caught sight of what Leo had seen. A footbot.

One footbot, then three. Then seven. Now fifteen. Raph's lips curled back as he drew out his sais and got ready for a fight. But there weren't that many, this would be a cake walk. Raph let out a battle cry and dived head first into the group of robots. Leo followed soon after. Ever kick or punch the two turtles threw, the farther away the footbots jumped. Soon enough, the turtles had cornered the group into a group of trees. Rare to see in New York City, but the local Natural Community Workshop had encouraged enough people to start growing something similar to a mini forest. Giving the final blow to the last of the footbots, Leo looked around to check if there was anymore surprise visitors. He didn't sense anything coming to attack, but he did feel a strange feeling in the center of his gut. A feeling that he could only describe as Dread.

Raph on the other hand was itching to get into another fight. To be able to stick his weapons through an object without killing anything. Keeping his anger about him, Raph started kicking and punching at the tree he was in front of. Leo only rolled his eyes at his younger brother's patience. But before he could place his blades back in their holders, another group of footbots came charging at them. Raph smiled. "More footbots? This is too good to be true!" he said as he greatly charged into the second fight. Leo was now on high alert. One group of footbots was considered normal, he found it weird that there was only a small amount, but it was normal. But two groups of only a small number of footbots was a little weird. Even weirder was that the footbots were all backing up in the same place. They were leading him and Raph deeper into the forest. Leo didn't like this one bit.

But before he could get a word out, the footbots suddenly started to attack more violently and more powerful than they had before. Raph and Leo were now the ones backing up. Dodging a ninja star aimed for his head, Leo felt the weapon bury itself into his shoulder, but he payed no attention to it. He looked over his shoulder to see a box. In the middle of the woods. Leo now saw what the footbots were doing. They were backing the turtles up into this little box, and Leo had no intention to find out why. "Raph! We have to move!" Leo yelled.

"What?! No way, we have to finish the fight!" Raph countered as he kept fighting while taking another few steps back.

"Raph, listen to me! We have to get out of here!" Leo said as he looked back again. He could now clearly see the big box, but not only see it but feel it as well. The closer they got to the mysterious box, the colder it got. Leo couldn't figure out what the initial plan of their enemy was, as he was too busy to think about anything but the fight. But he knew it wouldn't be good. Throwing one of his katana's into their holders, he quickly took his T-phone out and pressed the distress button. He would've texted one of his brothers to tell them what was happening, but a ninja star destroyed his phone before he could do anything else.

Leo really started to worry when they were no more than 15 feet away from the box. Raph must of also felt the temperature change because he looked back to see what the cause of the coldness was. When he did, the footbots took their advantage and used a roundhouse kick to push the turtles into the cube. Raph gave a small cry of pain before hitting the ground. Almost immediately, Leo gained his balance and stepped up to stop the footbots, but he was too late. The door had slam shut. In a fit of anger, Leo used his katana on the door. But it had no affect. He punched, kicked, and slammed his entire body into the door. But all he managed to do was give himself a few more bruises. "Well this is just great!" Raph pronounced, throwing his sais back into their pockets while sitting on the floor.

"Not only did we lose a fight to footbots, but now we're trapped in this-what is this thing? This, this BOX!" Raph yelled. "And it's all your fault!"

Leo froze. "How is this my fault!?" Leo asked.

"If you hadn't followed me, those footbots would never have found me and we wouldn't be here!" Raph countered.

"As I recall, I was the one who told you that coming up to the surface was a bad idea. I told you that gang activity was higher than usual and I told you that the Shredder was still hunting us. No doubt he's behind this." Leo said, mumbling the last part to himself.
Leo kept talking.
"I told you to not come up here, but did you listen? No! Because you let your ego and anger get the better of you! If you learned to control your anger better, we wouldn't get into these kinds of problems." Leo finished.

"I don't remember asking for your opinion" Raph retorted.

Leo said nothing, remembering his Sensei's words. "Let's just focus on getting out of here" Leo said, stepping away from the door and looking for another way out.

"It's no use. We're trapped." Raph said, turning his shell to one of the corners. "Just call the B Team and tell them where we are." Raph said. Leo took out his T-phone, which still had the ninja star stuck in the screen.
"Why don't you call them." Leo said, putting his T-phone back in his belt. As Leo put his T-phone back in it's pocket, he felt a stab of pain in his shoulder. Looking down, he noticed the small ninja star lodged in his skin. Looking back to make sure Raph wasn't looking, Leo quickly pulled the weapon out and shoved it into his belt. He moved his holder straps to cover the wound as Raph talked.

"I left my phone back at the lair. My goal was to get away from you guys." Raph mumbled, frowning. Silence then lingered on for a few minutes, Raph stayed sitting down while he watched Leo try to find a flaw in the trap they were now in. A while passed without any sound from either turtle, until Raph shivered. "Is it just me, or did it just get colder in here?" Raph asked.
Leo stopped examining the walls and started to pay more attention to the temperature around him. It was colder than before.

"It's probably just really cold outside and the temperature is affecting the box." Leo answered. Raph scoffed at Leo's answer, and that's when Leo lost it.

"What's your problem with me?" Leo asked, becoming fed up with Raph's attitude. "All you ever do is tell me what I'm doing wrong, like you could do better. I'm done with your attitude, so if you want to get out of this trap I suggest you start helping me find a way out instead of just sitting there and sulking." Leo said.
Raph said nothing but rolled his eyes and stood up to help his older brother find a way out. But as he did, he put pressure on his ankle and stumbled. Leo looked to Raph with a questioning look, but Raph brushed it off, hoping his brother wouldn't question it. It didn't take long to search the entire box, after all, it was only the size of a small tree house. You couldn't even fit a regular sized bed in it. As for how tall it was, it wasn't too tall but at least they didn't have to crouch down.

"Okay, it's definitely gotten colder." Raph said, crossing his arms over his chest.
"Yeah, definitely" Leo added, looking around one last time before finally giving up. Hopefully Donnie had gotten his S.O.S.

Master Splinter hadn't come out of his room, he was still meditating. He had gotten a strange feeling that he usually only got when his sons needed him. He had been trying to reach Leonardo through meditation, but the only problem was both people needed to be meditating for it to work. But Master Splinter kept trying. Mikey was also still in his room, most likely playing with his T-phone. Ever since Donnie had invented them, Mikey had been bad about staying up late and playing games on it. Sometimes he would stay up so late he would be too tired for training the next day. Donnie was no different. He too had a bad habit of staying up late and missing the extra hours of sleep that he most likely needed. Unlike Mikey, Donnie usually stayed up brainstorming or working on his other inventions to make them better. He would sometimes invent a whole new gadget in one night.

But tonight, Donnie was a little stressed and very worried. He had received an alert from Leo's T-phone, which meant he was in trouble. Donnie hadn't told Mikey nor his Sensei about the alert, he didn't want to involve them until he knew his facts. He knew it was Leo's T-phone that had sent the alert, and he had started to track it, but the signal was suddenly cut off. He then tried Raph's T-phone as he noticed that his hot-headed brother was also missing. The signal worked, but it had said that he was in the lair. After following the signal to Raph's room, Donnie discovered that Raph had left his phone there. Walking back to his lab, Donnie felt defeated. He didn't know what else to do. His two older brothers were missing, and he had no way to find them.
