It was one afternoon in Ponyville, inside the School of Friendship's dojo the ninjas were training some of the students. Yona was currently running through various slabs of stone set up and breaking them as she ran them down. She finally broke the final one down and ceased charging. Her friends who were watching from the side cheered her on, as Leo counted up.
"Perfect ten, Yona."
"You rammed those slabs down, yak girl." Mikey commended her.
"I got sensei Rocksteady to thank for training." Yona motioned to Rocksteady, who patted her head.
"Little yaks horns getting stronger and stronger."
"All right, students, that concludes today's training," Twilight dismissed the, "Don't forget tomorrow is our school picnic."
"So bring your appetites!" Pinkie cheered, as the students cleared out.
As the group started leaving, Sunset spoke, "It's nice of you to suggest we throw a picnic for the students, Twilight."
"Well, Mikey was the one who originally pitched the idea to me. As another chance for the students to get to know all of you." she replied.
"Wow, Mikey actually had a good idea for once." Raph said.
Mikey frowned, "I've had other good ideas before!"
"And the students deserve it with all the effort they've been putting into their work." Rarity put in.
"Oh, I have so much to bake tonight I just know the class is going to love it!" Pinkie cheered with excitement.
Meanwhile at the entrance to town, Shredder and Krang walked over and saw the town up ahead, "What the devil is that place?" Shredder asked.
"Ponyville, Shredder." Krang answered.
Shredder turned to his partner in disbelief, "How is it you know everything?!"
"The sign says it, Shredder." Krang answered dully while motioning to a welcome sign.
"Oh, well. Very well. Let's go." Before Shredder could go further, Krang stopped him.
"Hold on, Shredder. I don't want to draw too much attention to myself," Suddenly Krang sucked himself further into his bio-suit and the opening which revealed him closed up. Out from the android's mouth came Krang's voice, "There, this is more like it."
"Can we go now?" Shredder asked clearly annoyed.
"Of course. Right this way." Krang said, as the two proceeded into town.
As the villains strolled through town while trying to blend in, every so often several other ponies were giving them weird looks, "Your plan to not draw attention to yourself and me isn't working, Krang." Shredder whispered to his partner.
"Quiet, Shredder, and play along." the alien whispered back.
Suddenly the two stop as the young colt Featherweight was looking up at them oddly. Shredder spoke down to him, "Why don't you take a picture? It'll last longer!"
Featherweight taking Shredder's sarcastic claim seriously, pulled out his camera and took a picture of the two before bolting. Shredder growled, before calming down, "Krang, we've been here for less than five minutes and already I hate this town."
"Well, deal with it!" Krang argued, until the two heard familiar voice, "Wait, do you hear that?"
Shredder listened in, and his eyes widened, "No, that can't be!"
"Hide!" Krang grabbed Shredder and pushed him off to the side to hide.
Coming around the corner were the ponies, the ninjas, and their allies. As they were gossiping amongst each other, they passed a cafe table where Shredder and Krang held tall menus up as a means to conceal themselves. When the heroes passed them, the two lowered their menus and watched the group leave.
"I don't believe it!" Shredder said in shock.
"The Turtles of the other dimension, their allies, and the Rainbooms?" Krang asked in equal shock.
"Not to mention those traitorous turncoats Bebop and Rocksteady!" Shredder growled, before taking notice of Twilight Sparkle, "Hold it. Why isn't she wearing glasses? Did she switch to contacts?"
Krang looked and answered, "No, Shredder. It can only be Princess Twilight Sparkle."
"Princess?" Shredder asked in confusion.
"Yes. I faced her and the Rainbooms awhile back when Subprime offered me a chance to come home."
"But why are the turtles and the Rainbooms here at all?" Shredder asked.
"I don't know. So let's find ouuuuut." Krang answered, as they followed.
As the two villains trailed the heroes while making sure to stay hidden, they overheard their conversation, "I hope the students love my idea for a marshmallow chilli pepper pizza at the picnic tomorrow."
"You can only dream." Keno answered.
"Well, at least we'll be able to unwind for a change." Fugitoid noted.
"The Professor's right. All this teaching is tiring." Sunset admitted.
"Who would've thought being sensei's would be so tough?" Karai asked.
As they continued on, Krang spoke to his partner, "A picnic they're having? Shredder, feel like crashing the occasion?"
"For once, Krang, I actually agree with you," Shredder answered, as the two laugh before noticing Derpy flying behind them while giving them a confused look, "STOP LOOKING AT US!" Shredder snapped, as Derpy tilted her head before flying off.
They very next day, Twilight, her friends, and their allies were leading the children to a nice spacious spot in town to have their picnic. Up front with the girls were the CMC, "this is gonna be a great picnic," Applebloom began, "Thanks again for letting us join you on our day off, Applejack."
"Especially since we're not exactly students." Scootaloo put in.
"Well, you are Friendship tutors, and I think that more than qualifies you girls to join us." Twilight replied.
"I can't believe you three actually tried to get into the school through bizarre attempts." April told the three.
"And you actually thought they were willing to go so far as to sabotage one of your students, Twilight?" Casey asked.
Twilight sighed, "I know, I should've known the girls would never stoop that low. I was just so preoccupied being headmare I neglected to hear them out."
"At least Cozy came clean about it." Leo replied.
As they continued on, Shredder and Krang were watching them from behind a bush, "There they are." Krang noted.
"This plan of yours better work, Krang." Shredder warned his partner.
"Someone sounds snippy this morning."
"Really? Maybe it's because we had to sleep outdoors on the ground!" Shredder snapped, before Krang hushed him.
"Keep it down, Shredder! And follow me." the two snuck off.
When they reached the spot, every creature set up picnic blankets and were enjoying their food. As the girls and the ninjas were enjoying their food, Bebop noticed Spike eating gemstones from a basket close to him, "Dude, how can you eat gemstones?"
Rocksteady saw this, and spoke, "Da. Don't they hurt your teeth?"
"Nah. Dragons love this stuff." Spike assured them.
"Ya got that right." Smolder said, as she took some for herself.
Rarity sighed, before speaking to the two mutants, "You won't believe how much I have to hide my own gemstones I use in decoration with my fabulous outfits when Spike comes to my shop."
"Bros, is this a good day for a picnic or what?" Mikey asked.
"Michelangelo is correct, the day is absolutely beautiful." Fugitoid agreed.
"The pegasi sure are giving us a break today." Shini said.
"You bet they are." Rainbow confirmed.
"And for once we don't have any problems to deal with." Donnie finished.
Meanwhile not too far from the picnic, Krang was hiding and spoke loud enough while changing his voice up to sound like a different pony, "Help! Help! Somepony please help me!"
Back at the picnic sight, the ponies and the ninja friends overheard the voice, "Comrades, you hear that?" Rocksteady asked.
"It's a cry for help, yo!" Bebop gasped.
"So much for not needing to deal with problems today." Raph sighed.
"We better check it out." Leo suggested.
Twilight nodded and addressed the students, "Attention, every student! My fellow colleagues are going to step away for a moment, but we'll be back. None of you go wandering now." And with that, the group took off to answer the distress call.
As they left, the CMC and the Young Six were gossiping to themselves, "Whatever's going on must be important." Sweetie Belle said.
"I know. I wish we could see what it is." Sandbar said feeling envious.
"So why don't we?" Gallus suggested.
"Yeah. I say we check it out ourselves." Smolder added.
"But you guys we're not supposed to leave." Silverstream replied.
"Headmare Twilight specifically said not to go wandering." Ocellus added.
"Technically we can't get in trouble if we don't get caught now can we?" Gallus tempted them slyly.
"He does have a point." Applebloom noted.
"Well, ok." Ocellus said.
"So come on." Smolder said, as the group followed after the others.
The heroes rushed into another clearing armed and ready. Mikey called out, "Hang in there, we're here to save... you?" they looked around seeing no one in sight.
Twilight called out, "Uh, hello? Anypony out here? You said you were in trouble."
Suddenly the voice came back, "No, I'm not in trouble... but you are!" the last part changed into Krang's normal voice.
Suddenly everyone found themselves trapped in an energy cage. When Rocksteady accidentally touched a bar he was electrocuted, "Don't touch zappy bars." he said dizzily.
"What's going on here?!" Fugitoid demanded.
"What is this?!" Rainbow equally demanded.
"Well, duh! It's a traaap!"
The turtles, Twilight, Sunset, and their allies from New York gasped, "That voice." Leo began.
"No! It can't be!" Twilight said in shock.
"But it is!" Stomping right up to them was Krang who undid his concealment so all could see him in the chest cavity, "Surprise!" he gargled.
Rarity screamed in a panic, "What, in the name of Celestia, is that?!"
"Krang?!" the ninja group gasped.
"Here in Equestria?" Twilight asked in confusion.
"Indeed, Princess Twilight," he pointed to each of his captives), "And now I have you, the Turtles, their allies, Fugitoid, Sunset Shimmer, (to Starlight) I don't know who you are (Starlight scowled), and the Rainbooooms!"
The five other ponies looked at the alien in confusion, as Rainbow Dash asked, "Uh, Rainbooms?"
Krang frowned, "Don't play dumb with me! I recognize you girls anywhere. And you're going pay for my humiliating defeats!"
"What humiliatin' defeats?" Applejack asked in confusion.
"We don't even know you." Fluttershy added, while shaking in terror.
"And the only Rainbooms we know, is my legendary Sonic Rainboom." Rainbow boasted.
Krang double blinked, "You mean to tell me, that you don't know who I am?"
"Nuh-uh." Spike shook his head.
"Nope. This is the first time we've ever seen you before." Pinkie smiled.
Krang looked like he was about to have a migraine, "Okay, what's going on here?!"
Twilight spoke up, "Allow me to explain, Krang. You see, they don't recognize you because they're not the Rainbooms, but their pony counterparts."
"Counterparts, you say?"
"That's right. Much like the Turtles and their counterparts from your dimension, everpony has a human counterpart in their world. Including myself."
"Hmm," Krang pondered before resuming his evil demeanor, "No matter! We waited too long for our revenge!"
"We?" Spike asked.
"Wait," Leo began, "If Krang's here? Then that would mean..."
"That's right, you accursed turtle!" Stepping out from some shadows of the trees was Shredder, "I am here as well."
Karai frowned, "Shredder!"
"Oh, snap." Bebop gasped, as he and Rocksteady were nervous.
Spike spoke up, "Um... Is anypony gonna ask them how they got here? Cause, last I heard, their Technodrome got destroyed."
"Very true. But we're glad you asked." Krang replied.
Shredder explained, "After we broke out of the slammer, we enlisted the help of an old ally named Baxter Stockman."
"After showing him the plans for my matter transporter, he managed to transport the both us here. Then we began plotting our revenge. And now that we have you, we shall destroy you!" Krang declared.
"Painfully!" Shredder added, as the two laughed evilly while everyone gasped.
Meanwhile watching from the bushes were the Young Six and CMC who saw and heard everything, "Oh, no!"Silverstream, Ocellus, and the Crusaders gasped.
The villains ceased their evil laughter, as Shredder spoke, "But first, we're going to do something far worse!"
Sunset's eyes widened, "Oh, no..." she groaned.
Fluttershy asked fearfully, "What're they gonna do?"
"You're about to find out." Fugitoid answered, as his face gave off a dry expression.
"Prepare yourselves for... gloating!" Shredder declared.
"Excuse me?" Applejack asked in confusion.
"Gloating?" Twilight asked feeling annoyed.
"Are you for real?" Rainbow asked in disbelief, as the two started gloating at them.
"We are the best and you are not, you blasted ponies!" Shredder mocked.
"Puny Ponies!" Krang laughed.
"Mud-Headed Mules!"
"Inadequate Equines!"
"My Little Donkeys!"
Pinkie cried, as she covered her ears, "Make them stop!"
Fugitoid spoke to her and asked rhetorically, "Let me guess. You don't really find this torturous and are only acting up because you feel they should have this moment?"
"Wow! How did you know that?" she asked in surprise.
"Lucky guess." the professor replied.
"They are seriously as dumb as we are." Bebop told the group.
"And that is saying something." Rocksteady agreed.
From the bushes, the young ones watched the scene awkwardly, "Boy are those two dumb." Gallus said.
"We gotta do something!" Sweetie Belle panicked.
"But what?" Silverstream asked in worry, as the others were concerned on how they could help their teachers.
