After preparing for the trip, the group was walking through the jungle in the direction of Heart, Raya's home.
The reason? Since they were going to stay in that world for I don't know how long, what better way to make the most of that time than to explore that world?
"And there we were, walking through the sewers, with darkness enveloping us as the squirrelanoids were stalking us, ready to eat our brains." said Mikey.
"Wow. It's starting to scare me just hearing about it." said Boun.
Even Noi and the ongis were a little freaked out by the story.
"Ha. I would have swung my axe until I killed them all." said Tong.
"I can't believe that harmless little squirrels are so terrifying." said Sisu.
"That's the thing about mutagen. Sometimes those affected are good people, sometimes they turn evil, and sometimes they become like wild animals." said Leo.
"But you ended up normal." said Namaari.
"It's because we had Master Splinter." said Raph.
"Yeah, if it wasn't for him, I don't know what would have become of us." said Donnie.
"That Splinter sounds like a great warrior." said Tong.
"You speak so highly of him that I look forward to meeting him." said Sisu.
"And I'm sure he'll be thrilled to meet a real dragon." said April.
"Hey, Raya, how long until we get to Heart?" asked Casey.
"Not much. We should be pretty close by now and I can assure you that you're going to love it." said Raya.
"One question, wasn't Heart the kingdom that was in charge of guarding the Dragon Gem? What happened to it after the Druun left?" asked Raph.
"Well, after Sisu returned and everything went back to normal, we decided that, we each get to keep a piece of the Dragon Gem as a symbol that united, we can be stronger than apart." said Raya.
"Like pieces of a puzzle." said Donnie.
"Exactly." said Raya.
Suddenly, April felt a slight pain in her head, which the others noticed.
"What's wrong, April?" asked Donnie.
It was then that April's eyes widened in complete horror.
"Oh, no. Back off!" shouted April causing everyone to stop just as laser shots hit the ground in front of them, startling them all.
Soon after, four Kraang droids emerged from the underbrush and the mere sight of them caused the NY group's eyes to widen from shock.
"It can't be." said Leo.
"Impossible." said Raph.
"Do you know who they are?" asked Raya in confusion.
"Bad thing, sister. Very bad thing." said Mikey.
"Kraang recognizes those known as the turtles and their human allies." said the first Kraang droid.
"Kraang doesn't recognize the other humans who accompany those who are known as the turtles and their human allies." said a second Kraang droid.
"Kraang believes they are friends with those who are known as the turtles and their human allies." said a third Kraang droid.
"Kraang received orders to that effect in case what is known as a situation happened." said the fourth Kraang droid.
"Uh… What did they say?" asked Sisu.
"Take cover!" shouted Leo as the Kraang droids began shooting as the group split in two to take cover from the gunfire.
"Seriously, who are they?" asked Namaari.
"Long story. We'll tell you later." said Leo as he and his brothers drew their weapons.
Moving quickly through the gunfire, the turtles caught up with the Kraang droids and quickly decapitated them before they fell to the ground.
Seeing the gunfire cease, the others emerged from their hiding places and approached the fallen bodies of the Kraang droids.
"What did you do?" asked Raya.
"Uh, save your lives?" asked Mikey.
"But you killed them." said Boun.
"Oh, don't be alarmed. They're not their real bodies." said Casey.
"What do you mean by that?" asked Namaari.
That's when a Kraang popped out of the droid's chest and showed itself to everyone as it shrieked at them, which startled everyone.
Before the Kraang could think to do anything, Raph stomped it unconscious.
"This is his real body." said Raph.
"Okay, can you tell us what these things are?" asked Raph wanting answers.
"They are Kraang, a race from a different world than ours called Dimension X." said Donnie.
"For years, they've been trying to make our world a second home for them, but we've always thwarted their attempts." said Leo.
"Except for that one time when they took over the city and forced us to flee for a while." commented Casey.
"Actually, they were the ones who created the mutagen." said Mikey surprising the others.
"Wait, they created the mutagen that made you the way you are?" asked Sisu.
"Not only that, but they were the cause of my powers." said April.
"What?" asked Namaari.
"Long before I was born, my mother was captured by the Kraang and subjected to their genetic experiments. The result of that was for me to gain these powers, as well as being part human, Kraang and mutant." said April.
The group of listeners were shocked, as they didn't expect that the origin of her powers was that something so horrible.
"So what are these things doing here?" asked Tong.
"I don't know, but if there's one thing we know about the Kraang, it's that they don't usually go off on their own." said Leo.
"So what are they planning?" asked Boun.
"We'll find out soon enough." began Raph picking up the Kraang he knocked unconscious and putting him back in his place, waking him up in the process. "You. Start talking or our little friend will have squid for dinner tonight." said Raph pointing at Sisu.
"I'm not going to eat that." said Sisu.
"Yeah, but he doesn't know that." whispered Mikey.
"Kraang has orders to secure what is known as the perimeter." said Kraang.
"Don't they have any other way to talk?" asked Boun.
"You get used to it eventually." said Casey with a shrug.
"Kraang mustn't allow anyone to enter or leave what is known as the human settlement Kraang is attacking." said Kraang.
"Human settlement?" asked Leo.
Suddenly, Raya's eyes widened in horror as she realized something terrible.
"Oh, no!" exclaimed Raya before quickly breaking into a run.
"Raya, wait!" exclaimed Namaari as she and the others followed her running.
It was only a short time before they caught up with her.
"What's wrong, Raya?" asked April.
"The closest human settlement to this place is Heart!" said Raya.
"And if the Kraang were guarding the perimeter…" began Leo.
"It's because they must be attacking the kingdom." finished Donnie in horror.
"We can't waste time!" said Raya before picking up the pace, with the others following close behind, though Boun, Noi and the ongis were riding on Tong's shoulders so they could keep up.
Soon after, they finally reached the outskirts of the jungle, in front of the bridge that served as the entrance to the kingdom, where they had a clear view of Heart, but unfortunately, they didn't exactly have an expression of joy on their face, but one of horror.
All over the place, there were Kraang droids shooting non-stop, destroying everything in their path as people were fleeing in panic.
There were also some Heart warriors who tried to stop them, but the Kraang's advanced weapons eventually drove them back.
"They must be stopped!" exclaimed Raya about to pounce, but Leo grabbed her by the arm.
"Hold on, Raya. Don't be hasty." said Leo.
"It's my home that's under attack! My ba is in there!" said Raya with extreme concern.
"I know and I understand your concern, but you don't know this enemy as well as we do." said Leo.
"He is right. The Kraang are totally different from those Jaw warriors we fought because of their advanced technology." said Donnie.
"Trust me. Throwing yourself headlong into danger isn't a good idea in this case." said Raph.
"So what do you suggest we do?" asked Namaari.
"There is no way I plan to stay here while there are humans in danger." said Sisu.
"Of course not, but we have to come up with a plan." said April.
"Raya, you know this place perfectly well, don't you?" asked Leo.
"Like the back of my hand." said Raya.
"Okay, so here's what we'll do. Raya, Sisu and I will go find Raya's father and explain the situation to him. That way, we can arrange things. The rest of you, try to take down as many Kraang as you can." said Leo.
"That's a plan I'm willing to go along with." said Tong with a toothy grin.
"Have no trouble restraining yourselves. You've seen his true appearance." said Leo.
"Trust me, I won't forget." said Boun.
"We must hurry then. Get on." said Sisu before Raya and Leo climbed on her back.
"Do you think you can run all the way to the palace?" asked Leo.
"Run? Did I say I'm going to run?" asked Sisu before taking a big leap.
Suddenly, as if by magic, small, transparent tiles formed in the air under Sisu's paws, allowing her to be able to run in the air at full speed.
Needless to say, the NY group was completely amazed by that.
"Can she fly?" asked Casey.
"How is that possible? It doesn't even have wings!" said Donnie.
"We'll talk about dragon biology when they're not attacking the kingdom." said Raph as he and the others readied their weapons.
"Here we go! Booyakasha!" shouted Mikey as they all launched into battle.
Sisu went flying over the ground out of sight of the Kraang.
While Leo was amazed by the fact that he was flying on the back of a dragon, Raya was very worried, for all the while she was looking at what was going on below and the destruction the Kraang were causing in her home.
"Raya, where do you think your father will be?" asked Leo.
"Knowing him, he'll surely be helping people to safety." began Raya before turning her attention to Sisu. "Go to the stairs leading to the palace."
"Understood." said Sisu before starting to ascend as her passengers held on tightly.
As they climbed the massive mountain, they saw some Kraang droids climbing the stairs as some warriors tried to fight them, only to fail and retreat.
They continued climbing until they spotted a man who was holding his own against the invaders despite the disadvantage.
It was a man, but not just any man. That man was Chief Benja, Raya's father and chief of Heart.
"Come on, come on! Everybody inside!" said Benja as the people rushed quickly toward the palace.
Suddenly, several Kraang droids appeared in front of him.
"Resistance against Kraang is what is known as futile." said one Kraang droid.
"Kraang demands from the human what is known as surrender or Kraang will open fire." said another Kraang droid.
"I don't intend to surrender to invaders such as yourselves." said Benja with determination.
"Kraang warned. Prepare to what is known as die." said the Kraang droid as he and the others prepared to shoot.
Benja prepared to fight despite the odds against him when…
"BA!"
Looking up, Benja saw his daughter, Sisu and Leo fall in front of him.
Before they could say anything, Raya and Leo moved quickly and used their weapons to smash the first Kraang droids before Sisu gave the others a pigtail that sent them far back on the stairs.
"Raya?" asked Benja in surprise.
"Ba, are you okay?!" asked Raya going to her father.
"I'm fine, take it easy." said Benja.
"Sir, you need to get everyone to safety." said Leo.
"What? who are you?" asked Benja surprised to see someone like him.
"A friend of ours." said Sisu.
"Raya, what's going on?" asked Benja.
"I'll explain later, but you have to go and protect everyone." said Raya with a serious look.
That was enough to convince him.
"Okay, just be careful." said Benja.
"Tell your men not to hold back when fighting them. They're metal beings, so they're not alive." said Leo.
"I will." said Benja before the three of them went downstairs.
He may not have known who that humanoid turtle or the invaders were, but he trusted his daughter and knew that if she was with him, she was a good person.
He could only hope they stayed safe.
"Goongala!" shouted Casey throwing several explosive disks that knocked down several Kraang droids.
Suddenly, three Kraang droids moved up behind him and aimed their weapons, but then, the ongis stood on their heads and turned them to face backwards, which they took advantage of to steal their weapons, giving Casey, just enough time to take them down with his field hockey stick.
"Thanks for the help, friends." said Casey before skating away.
Casey skated away to dodge the laser shots and when he got close to the Kraang droids shooting, he hit them hard with his baseball bat, knocking them down in the process.
More Kraang droids came right over, but then, gunfire quickly tore them apart.
Looking over a box, it was discovered that it was the ongis who did it with the Kraang weapons they had stolen.
The one with a conical hat made a blow to the tip of the gun like a western cowboy.
April jumped to the side to dodge the Kraang's shots while holding Noi in her arms.
"Hold on tight to me and don't let go!" said April receiving a squeal from Noi in agreement.
Using her ninja training, April moved back and forth to dodge the incoming shots before pulling out her tensen and throwing it like a frisbee.
With the help of her powers, she moved the tensen so that it was slicing the Kraang droids to pieces.
After retrieving her tensen, she began using it as a shield for shots as she approached the nearest Kraang droids and knocked them down with fists and kicks.
While she fought, Noi spent her time shooting rocks with her slingshot, but due to the metal structure, it didn't hurt them at all.
Then, thinking of something else, Noi shot a rock directly into the hole of a Kraang droid's gun, causing the moment the droid pulled the trigger, it exploded, knocking the droid down in the process, much to the amusement of the baby who began repeating the process with any Kraang droid in sight.
April couldn't help but smile at the baby's bravery despite her age.
Boun was running through the streets of Heart until, as he rounded a corner, he saw a pair of Kraang droids who, the moment they saw him, began shooting, though fortunately, Boun was able to protect himself by getting behind a wall.
"Okay, okay. Calm down. You saw that they're just some alien brains in metal bodies, so no problem. It'll be just like fighting those training dummies." began Boun trying to calm himself down before a nearby shot shattered a part of the wall's edge. "Only these dummies have weapons that will kill me on the spot."
With a bit of gathered courage, Boun looked around until he saw something that gave him an idea.
The Kraang droids kept shooting until, suddenly, a barrel shot out from around the corner and, by reflex, the Kraang droids shot the barrel into splinters.
The two droids bowed their heads in confusion not realizing that Boun had scaled the wall and was now on the roof of a building next to the two droids.
Slowly and swiftly, Boun climbed down from the roof and moved towards the Kraang droids while drawing his karambit knives.
Before they could react, Boun leapt between the two Kraang droids and in one swing, quickly decapitated them, knocking them down in the process.
Boun spun his weapons around with a grin as he watched the Kraang jump out of their droids before quickly crawling away from there.
"Ha. If only my brother could see me now." said Boun.
Donnie dodged a couple of enemy shots before charging towards the Kraang droids and taking them down quickly with swipes of his staff.
One Kraang droid, who was a bit away from him, was about to shoot him, but Donnie stretched the staff as far as he could towards him and thanks to the hidden blade, impaled him in the head, which caused him to be knocked down.
After that, he saw a pair of Kraang droids approaching him, but he swung his staff quickly like a propeller before delivering a swing that knocked them both down.
"Hey, tin-heads!" shouted Mikey drawing the attention of several Kraang droids. "I've seen toy robots smarter than you!"
"Kraang won't tolerate what is known as insult!" said the Kraang droid before they started shooting, but Mikey jumped to the side to avoid the shots before running towards them.
As he approached them, he hit a few with his nunchucks before throwing his chain that wrapped around another Kraang droid and then, with a jerk, spun it around so that it hit another Kraang droid, stunning it a bit in the process before Mikey kicked it down.
Tong swung his axe back and forth, smashing any Kraang droids in his path.
"Ha. I'm starting to like smashing these things." said Tong before being met by multiple shots, forcing him to take cover.
It was then that he noticed a cart near where he was and with his strength he picked it up and threw it towards the Kraang droids, managing to take down some of them.
Before the other Kraang droids could react, Tong smashed them with his axe before grabbing the last two by the head and crushing them with his hands.
Suddenly, he saw a group of Kraang droids heading towards him.
"For someone from Spine, that's nothing more than mere training." said Tong crunching his fists before charging towards them with his axe at the ready.
Raph moved from side to side to dodge the gunfire as he charged toward the Kraang droids.
With one sai, he disabled one Kraang droid's weapon before using the other to decapitate it.
He then approached another Kraang droid and knocked it down with a punch.
Namaari had to admit that she had never imagined fighting strange creatures from another world that carried deadlier weapons than she could imagine, but they were attacking her friend's home and she wasn't going to stand by while they continued to cause damage.
With her swords, she went about annihilating any Kraang droids that came her way.
After taking down another Kraang droid, she had to duck to dodge shots from a pair of Kraang droids.
She threw one of her swords, plunging it into a Kraang droid that was knocked down and moved quickly and used the other sword to take down the other Kraang droid before retrieving the previous sword.
Suddenly, she was completely surrounded by Kraang droids that aimed their weapons at her.
Despite the situation, Namaari wasn't willing to give up and got into position to fight even though that could be the end of her.
However, before any Kraang droid shot, something moved quickly between them and soon after, all the Kraang droids fell to pieces.
Namaari was confused by this until she saw that, in front of her, there was a girl with a suit of armor and a katana.
"Are you okay?" asked Karai turning to see her.
"Yes, thanks for the help." said Namaari.
"You'd better get to a safe place, this might get the better of you." said Karai.
"I appreciate the concern, but I don't plan on letting these creatures do whatever they want in this place." said Namaari.
Before Karai could say anything…
"Namaari!"
The two girls looked to the side to see April arrive on the scene.
"How are things going for…?" began April before stopping as soon as she saw the other girl. "Karai!?"
"April! I'm glad you're okay!" said Karai happy to see her friend.
"How did you get here?" asked April.
"It's a long story." said Karai.
"Wait, are you Karai? The turtles' sister?" asked Namaari in surprise, as she didn't expect to meet her so soon.
"You know my brothers?" asked Karai.
"That's a long story too." said April.
That's when Noi peeked out from behind April.
"What's a baby doing here?" asked Karai.
"Oh, helping us fight the Kraang." said April like it was no big deal.
"You let a baby fight the Kraang?!" asked Karai angrily and surprised.
"In her defense, she came with us when all this happened and she's proven herself capable of defending herself." said April as Noi let out a couple of squeals with her arms crossed.
"Ugh. Okay, but when this is over, we're all going to have a long talk about this." said Karai before going the other way.
"I'm sorry you had to meet her like that." said April.
"That's okay." said Namaari.
After that, the three of them set off again to fight the Heart invaders.
As they made their way down the stairs, Leo, Raya and Sisu were taking down any Kraang droids in their path, helping the Heart warriors in the process.
By the time they reached the bottom of the stairs, they spread out a bit to deal with the large number of Kraang droids.
Sisu took advantage of her scrawny body to avoid enemy gunfire.
"You don't get me. You don't get me. You missed. You missed again. You need to improve your aim." said Sisu as she dodged the shots.
"Kraang doesn't recognize the creature that seems to be allied with the ones known as the turtles." said a Kraang droid.
"Kraang needs to get data on the strange creature." said the other Kraang droid.
"I still don't understand what you are saying." said Sisu before swinging her tail to take down several Kraang droids.
Before a couple of them shot with their weapons, Sisu grabbed them and slammed them into each other, destroying them in the process.
Soon after, the Kraang jumped out of the destroyed droids and took off running.
"Yuck. After this, I'll pass on squids for a season." said Sisu.
Raya used her sword to block the Kraang droids' shots as she headed towards them and when she reached them, she attacked them with her sword, taking down several in the process.
Then then, she saw several Kraang droids approaching her with their weapons at the ready, so she turned her sword into a whip and began lashing out.
Most of the lashes cut some Kraang droids due to their sharp side and one lash caught a Kraang droid before, with a jerk, she sent it crashing into another Kraang droid.
After that, she turned her whip back into a sword and charged at the remaining Kraang droid.
It tried to shoot her, but Raya jumped to dodge it and with one swing, decapitated it with her sword.
Leo used his katanas to block the shots as well as deflect some to hit themselves.
When he saw his chance, he charged towards them and began to take them down with his weapons.
Leo felt a Kraang droid approach him from behind as he pointed his weapon at him, but the moment he turned around to answer that, a sword pierced the Kraang droid from behind.
As the Kraang droid fell to the ground, Leo was shocked to see who the person was that saved him.
"Karai?!" asked Leo in shock.
"Surprised to see me?" asked Karai with a smile.
"But… What? How did you…?" asked Leo.
"We'll talk about it later. There are still a few left out there." said Karai.
Although he wanted answers, he knew the situation was more important, so he gave her a nod with a serious look before heading off to the side.
Raya shot down another Kraang droid before noticing that the area was clear.
Soon after, the others arrived, though the NY group was surprised to see a certain person.
"Karai?!" asked Raph, Mikey, Donnie and Casey at the same time.
"Hello everyone." said Karai.
"How come you're here?" asked Donnie.
"I'll explain later." said Karai.
"Wait, she's your sister?" asked Raya.
"Wow. She's not like I had imagined her." said Sisu approaching her for a closer look.
Needless to say, Karai was shocked as soon as she saw what she was.
"A… dragon?" asked Karai.
Before anyone could say anything else, they began to hear heavy footsteps.
Looking in one direction, everyone was shocked to see three Kraang bio-droids.
"Oh, great. They've brought in the heavyweights." said Raph.
"Ha. Is that supposed to intimidate us? I've taken down sturdier trees than those." said Tong.
"It's not the looks we should be worried about." said Casey.
That's when the bio-droids turned around and crouched down as a compartment opened up in their backsides to reveal a pair of missiles per bio-droid.
"They've got butt cannons!" shouted Mikey before the missiles were shot at them.
They quickly took off running in time to escape the missiles that hit the area where they were before.
After that, the bio-droids reared up and let out a gorilla roar before charging towards them.
"If you think that will be enough to scare me, you're wrong." said Tong before charging towards one of them.
The moment they got close, they threw their hands towards each other, trapping them together in the process as they pushed each other away.
They stayed like that for a while until the bio-droid opened a compartment in its chest and shot a chainsaw attached to a chain, but Tong managed to pull his head away just in time and before it could retrieve its weapon, Tong, with a groan of effort, managed to push the bio-droid away from him, giving him just enough time to grab him by the body, lift him onto his shoulders and throw him towards the wall of a building.
A bio-droid approached Boun, Mickey and Donnie, with the three of them readying their weapons to fight.
"Uh… Any more advice about them?" asked Boun.
"Just see to it that he doesn't hit you directly." said Donnie.
"That's pretty obvious." said Mikey.
Suddenly, however, the ongis showed up on the bio-droid's back and pulled hard on a plate where the neck was, which was where the Kraang piloting the thing was located.
When they managed to remove it, they saw a bunch of wires inside and the ongi with the big head grabbed a wire before biting into it, getting electrocuted in the process, but that made the bio-droid start hitting itself in the head a couple of times before falling to the ground knocked down.
"Woohoo. Nice one, friends." Mikey said.
The ongis gave him a thumbs up before high-fiving each other, but because the medium-sized one was electrocuted, the moment they touched him, the other two were also electrocuted.
That was witnessed by Karai, who was surprised by that.
"Did you also bring monkeys to the battlefield?" asked Karai to Leo.
"It's a long story." said Leo.
Raya and Namaari moved back and forth to dodge the attacks of another bio-droid.
The bio-droid raised its arms to crush them, but then, Sisu coiled around it, which the Kraang manipulating the droid noticed.
"Hey, brain head, what do you say we play a game? I called it 'roll the droid'." said Sisu before giving her own body a tug that caused the droid to spin rapidly like a spinning top.
By the time it finished spinning, the bio-droid wobbled from side to side looking very dizzy.
Taking advantage of that, Raya and Namaari jumped at it and gave it a double kick that sent it sprawling backwards.
Before they thought they had won, the bio-droid got up, looking very angry, as did the bio-droid that knocked Tong down, who had also gotten up.
"They're tough as nails." said Namaari.
"How are we going to beat them?" asked Raya.
"Maybe we can't, but there's someone who can." said Karai.
"What do you mean?" asked Casey.
"Did you really think I would go alone to find you in another world?" asked Karai.
The bio-droids were about to launch into an attack, but then, something hit them and knocked them backwards.
The NY group was completely shocked when they saw that, in front of them all was a humanoid rat wearing a kimono and carrying a staff.
"I hope I wasn't too late for the fun." said Splinter.
"Master Splinter!" exclaimed the NY group with glee.
"That… That's Master Splinter?" asked Raya in surprise.
"The master of the turtles?" asked Namaari in surprise.
"Wow. He's taller than I imagined." commented Boun quietly.
"Sensei, how did you…?" asked Leo.
"Explanations come later, Leonardo. First let me take care of those two." said Splinter turning to see the bio-droids get up.
"Kraang recognizes the one known as Splinter." said a bio-droid Kraang.
"Even though Kraang knows of the abilities of the one known as Splinter, Kraang has orders to annihilate any allies of the one known as the turtles." said the other Kraang bio-droid.
The bio-droids again shot their butt missiles that flew directly at the mutant rat.
Splinter dodged a couple of missiles before using his hands to deflect the other missiles to hit elsewhere.
With great speed, Splinter approached one of the bio-droids, who tried to hit him with its fists, but the mutant rat dodged all the attacks with ease as if they were nothing.
After dodging another punch, Splinter connected several blows to the arm that rendered it unusable and then gave it a strong kick that knocked it down.
The other bio-droid lunged to attack him, but Splinter reacted quickly and delivered several punches and kicks in a swift manner to the bio-droid's body before he extended his index and middle fingers just inches away from the bio-droid.
It was then that an invisible force sent the bio-droid flying straight into the other, knocking them both down in the process.
Needless to say, everyone in the group (outside of the NY group) was in shock at the mutant rat's display of power.
Before long, the NY group approached him.
"Master Splinter, you were amazing." said Mikey.
"I never doubted you could defeat those things." said Casey.
"You're always able to surprise us." said Leo.
"My children, my friends, I am glad to see you again." said Splinter.
"And so am I." began Karai with a smile before that smile changed to a frown. "But I'm also angry. May I ask what you have been doing that you haven't shown any signs of life?"
"Again, it's a long story," Leo said.
"Sorry."
Splinter turned his gaze forward to see Raya and her friends approaching them.
At first, he thought about running away quickly given his history of encounters with humans, but seeing the confident smiles of his children and friends, he knew these people were trustworthy.
"Are you Master Splinter?" asked Raya.
"That's right." said Splinter.
"I am Raya, daughter of Chief Benja of Heart, and on behalf of the kingdom, I thank you for helping us." said Raya with a smile, much to the mutant rat's surprise.
His surprise increased even more when Sisu stood in front of him.
"It can't be." said Splinter in amazement.
"Master Splinter, it is a great honor to finally meet you." said Sisu.
"The honor is all mine, honorable dragon." said Splinter in respect.
"Oh, please. We are among friends. Just call me Sisu." said Sisu.
"We know you have many questions." said Donnie.
"But we will be happy to answer them all." said Leo.
