"So let me see if I understand this." Rarity, Starlight, Spike, and the rest of the Main Six were sitting in the throne room together, examining Twilight's Yo-kai Watch together. "That little piece of plastic is actually something used for summoning things called..." She twisted her hoof, the name escaping her tongue.

"Yo-kai." Twilight nodded and brought the watch closer to the middle. "Yo-kai are invisible creatures responsible for the world's ups and downs. Whenever someone feels mysteriously hungry, can't remember anything, or just wants to be a slouch, that means that a Yo-kai's essence is controlling that pony, and they just pass it off as normal behaviour."

"But, if they're invisible, then how do you know they exist?" Rainbow Dash raised a brow and flapped over to the watch.

"Because this device is the only thing that allows me to see them." Twilight popped up the lens and pointed it at Whisper. She then showed it to the rest of her friends. "Look through here, and you'll see what I mean."

The rest of the room walked up to the watch and peeked through the lens. Once they did, they could clearly see Whisper giving them a warm smile. They looked without the lens and saw that he was indeed invisible.

"You mean..." Rainbow Dash let the thought fester in her head for a while.

"WHAT?!" Everyone else in the room chorused in perfect harmony.

"So, whenever you suddenly feel hungry, need to go to the bathroom, or tell a secret when you meant to say hello, that's a Yo-kai's work." Twilight brought the lens back to her friends. "And this little ghost next to me is Whisper. He's a butler, my guide to all things Yo-kai, and my supposed conscience for now."

"I'm also a grade-A chef, would you believe it?" Whisper gave a little chuckle. "But for some reason, Twilight doesn't seem interested in any of my meals..."

"That's because whenever I try to eat your meals, they always go right through me." Twilight turned towards him.

"Well, that's why the recipe is so secret!" Whisper flapped his arms at Twilight. "What did you expect from such things as ghost pie or spirit tea?"

"I'm guessing the secret is that it's only eatable by ghosts." Starlight deadpanned, causing everyone else but Whisper to laugh.

"Not funny." Whisper scoffed and turned his back to the ponies.

"So, how'd you find that cute little thingamajig, Twilight?" Pinkie Pie bounced up and over the watch before her eyes literally bulged out looking at it.

"You know that ghost story you said in the Everfree Forest the other night about the girl who disappeared after opening that capsule prize?" Twilight saw Pinkie nodding already. "Well, as it turns out, it was somewhat true. Whisper told me most of the specks on it, but he never told me about what happened to the mare in question."

"If she were in the Yo-kai World, someone would have told me by now. Nothing ever gets into the Yo-kai World except Yo-kai and a select few humans nowadays." Whisper tipped his hand.

"So wait, how is it that we can't see Whisper on the outside world, but we can hear him talking?" Fluttershy looked at Whisper, then the blank space where she couldn't see him without the watch. "It makes no sense."

"Oh. On the way back to the castle, I did some minor tinkering with the Yo-kai Watch." Twilight used her other hoof to show her friends the changes she had made. There was a speaker in the middle of the interior frame, as well as numbers and hands to tell the time. "Not only can it function like an ACTUAL watch now, but it also allows Yo-kai to talk to other ponies who don't have one of their own. Pretty sweet, huh?"

"How in the world did you make that while we were walking?" Whisper looked at the speaker and clock hands closely. "You seemed like you were having so much fun with your friends as you were talking to them about showing off the watch and what it could do, that I never would've guessed that you could alter the Yo-kai Watch at the same time."

"Whisper, I'm a multitasker. You should know that by now." Twilight smiled a little as she looked back at him.

"Well, you are pretty much the only pony I know who can stack books, write letters, and make food all at once, so there is that." Whisper looked at Twilight's horn. "Still, how? You looked like you were doing so much, that wouldn't you at least strain and struggle trying to pull it off?"

"Listen, buddy. Twilight here has done plenty of other things that'd blow your ghostly socks off." Rainbow tried to jab Whisper's stomach, but her elbow went right through his chest.

"Big deal, then. I don't wear socks." Whisper chuckled again at Dash's remark.

"Ugh! It was just a figure of speech, y'know!" Dash flew back to the rest of the group.

"Well, Twilight is the only pony who not only stood up and saved Princess Luna from Nightmare Moon; fixed our friendships so we could defeat Discord; used all of her power to stop Lord Tirek—" Pinkie was cut off by Starlight's hoof in her mouth.

"And stop me from re-writing the past to change the future." Starlight hung her head and curled her tail back.

"Whoa..." Whisper looked at Twilight, who had a smug and proud grin on her face. "You really did all that?"

"Yep. You're looking at Equestria's greatest hero right there, Whisper." Applejack tipped her hat back and gave Twilight a small hug. "We've been following in her footsteps ever since the Nightmare Moon incident a while back."

"In just one word, Twilight, you're incredible." He flew down and shook her hoof again. "I'm honoured to be your guide for the adventures you're going to have in Ponyville and beyond."

"Aww... Thanks, Whisper." Twilight gave him a small cuddle, which he was happy to return."

Meanwhile, as everyone was talking about Yo-kai, where Whisper came from, and other topics relating to the manner, a red mosquito creature cast a mean look at Pinkie Pie. Grunting, the insect flew over and dived its' nose right into Pinkie's brain, giving her a purple flame, just like before.

"So, Pinkie, aren't you excited to be a part of this adventure?" Twilight walked over to Pinkie and grinned at her.

"Not really." Pinkie pushed Twilight away, watching her happy expression evaporate instantly. "All of this just seems like a bunch of hooey. Why do little bugs have to control everything? Can't we decide for ourselves? It just ticks me off, quite frankly."

Everyone's mouths were agape with what Pinkie had said. Never in their lives had they seen her acting so negative, and Spike himself fainted over the sentence.

"Pinkie? What's gotten into you, girl?" Rarity slowly walked forward and reached her hoof out, only for Pinkie to slap it away, grumbling.

"Stay away from me. I'm not in the mood right now for any of my games." Pinkie crossed her hooves and sat down, glaring at her friends.

"Do you think there's a Yo-kai inspiriting her?" Fluttershy whispered to Twilight.

"Could be. I'll give her a quick scan." Twilight pointed the lens at Pinkie Pie and watched it light up to reveal the Yo-kai. As Pinkie muttered gibberish that could only be described as pessimistic hate comments, the mosquito was sucking something up through its' nose.

"Why does she have to be so positive all the time?" The Yo-kai sighed. "She needs to know the word 'negative' one way or another..."

"That is Negatibuzz." Whisper hovered over to Twilight. "If Negatibuzz inspirits you, your mood can become foul in a snap. Even the most joyful of ponies like Pinkie aren't safe from this grumpy, mean, and downright rude creature."

"Well? What's wrong with her?" Rarity asked Twilight.

"Something called Negatibuzz is inspiriting poor Pinkie, making her the grumpiest grump you'll ever see." Twilight pulled out a Yo-kai Medal and clutched it tight. "But don't worry, girls. I know just the Yo-kai that'll give Pinkie Pie her smile back.

"Come on out, my Yo-kai friend! Calling Heheheel!" Twilight threw the medal skyward, just like the others. "Yo-kai Medal! Do your thing!" And she similarly shoved it into her watch.

"SUMMONING: SLIPPERY!" The watch boomed, as light blue snakes danced in the air, causing Heheheel to appear and dance along with them as they flew through the air and crashed down on the ground.

Trippery!
Gippery!
Slimey-wimey do,
Slippery!

"Heheheel!" The snake bowed his head as his urn landed delicately.

"What in the heck was that, Twilight?" Applejack's eyes were wide in disbelief. "I mean, I understand the beams of light, but not that song that came out of nowhere!"

"Look, girls." Twilight showed them the lens again, revealing both Heheheel and Negatibuzz staring each other down. "The snake is my Yo-kai, Heheheel, while the other one is a wild Yo-kai called Negatibuzz."

"So that disgusting insect is what's making Pinkie Pie into Grumpy Pie?" Rarity spat to the side as she turned away from Negatibuzz. "Honestly, such a filthy creature shouldn't even be here."

"But then again, that snake is what turned you into a laughing hyena back at the boutique." Twilight rolled her eyes as she showed Rarity Heheheel."

"Touche..." Rarity eyed up both Yo-kai, using her hoof to say that she was watching them.

"Heheheel. Why did you come to this world too?" Negatibuzz groaned as he looked at the snake bemusedly. "You're just going to cut me out of the market again, aren't you?"

"Nope! I heed Twilight's call now!" He was still laughing and giggling crazily. "Wherever she goes, if she needs me, I'm there in two shakes of a snake's tail!"

"Sigh. Everything just seems pointless with you around to spoil the fun." Negatibuzz flew out of Pinkie's head and buzzed its' wings faster. "Well, if you are going to break my inspirit on this pink horse, then I'm not going out without a fight!"

"Bring it on!" Heheheel licked its' lips and hurled itself at Negatibuzz, who simply flew aside.

"Weak. Just what I expected from a snake stuck in its' pot." Negatibuzz drove its' nose into Heheheel, sucking up something and making the eel yelp in pain, but still giggle. "Don't you feel weak stuck in that thing? Do you want to break out?" He cast a purple flame on the Yo-kai, making it stop laughing.

"Actually, why am I in this pot?" Heheheel looked down at where his tail should be. "I could be out there, wriggling around the world, but I'm just stuck in something dumb for the rest of my life."

"Heheheel? What's wrong?" Twilight looked at what had become of her Yo-kai. "Why are you negative too?"

"Oh, did I forget to mention? Yo-kai can inspirit each other in combat as well." Whisper crossed his arms and peaked over Twilight's shoulder. "Heheheel might be a laughing sack, but even he isn't immune from Negatibuzz's inspiriting powers."

"Then there's only one other way to fix this." Twilight pulled out another Yo-kai Medal. "Come on out, my Yo-kai friend! Calling Buhu! Yo-kai Medal! Do your thing!" She repeated the process at a much more rapid pace and saw Buhu appear instantly, without the watch calling it out.

"Oh, hey, Twilight. What's up now?" Buhu looked up at Twilight.

"Wait. Buhu?!" Negatibuzz's eyes went wide as he looked at Twilight's new Yo-kai ally. "Why didn't you tell me you were friends with Buhu? That puts a whole new spin on things!"

"Negatibuzz?!" Buhu looked at him.

"You two know each other?" Twilight raised a brow as both Yo-kai flew up to each other and gave off small smiles.

"Yeah. Buhu was my partner back in the day." Negatibuzz still kept up his attitude, but his voice felt a little better in mood. "Together, we created the ultimate depression combo. Making people cry, making them doubt themselves, oh, those were the days."

"For you, maybe. I can't imagine how it must've been for the other people you inspirited." Twilight shivered and rubbed the ground with her back hoof. "Still, it's great that you two know each other."

"Oh yes. Yo-kai aren't like animals, Twilight." Whisper nodded and watched Buhu and Negatibuzz fly off and talk. "Most of the time, certain Yo-kai are friends with one another, have worked together in the past, or even got married."

"Yo-kai can marry?!" Twilight's mouth fell wide open again.

"Yes. It's a weird and wonderful thing, don't you agree?" Whisper said as he watched both Negatibuzz and Buhu return.

"Alright, Twilight. I'm not really one to trust humans much, but Buhu here says that you've really opened up to him." Negatibuzz looked back at both Heheheel and Pinkie and removed the purple fires. "Buhu is probably the only friend—or at least acquaintance—that I've had, so I want to make sure that he's safe and with me at all times. I don't usually hand this out, but he is my chum, and so I just want to make sure in case we get lost again." The white flash happened again, and a Yo-kai Medal dropped into Twilight's hoof. "My Yo-kai Medal. You probably won't need it, but you're going out befriending Yo-kai, so, whatever."

"Thanks, Negatibuzz." Twilight smiled.

"Don't mention it. Ever. To anyone." Negatibuzz looked away and disappeared with Buhu.

"Girls? What happened?" Pinkie Pie shook her head and looked at the rest of the Main Six. "Was I a bad pony?"

"No, Pinkie." Twilight walked over to Pinkie Pie and helped her stand back up on four hooves. "You just had some mosquito Yo-kai sucking on your brain and turning you into a meanie. It's gone now, though." Twilight looked back at Heheheel. "Actually, Heheheel? Do you mind giving Pinkie Pie her laughter back?"

"Sure thing, Twilight! I love to see people laughing! It makes them forget about their worries!" Heheheel laughed so much that he shot off his own inspiriting flame that took Pinkie in seconds.

Pinkie let a small chuckle slip, but it soon rose into a giggle, then into full-blown laughter. As she laughed, tears streamed from her eyes as she flopped onto her back, kicking her legs out all over the place as she let the feeling take her.

"Pinkie sure seems happier now." Whisper watched Pinkie continue to laugh under Heheheel's influence.

"Yes. Pinkie's usually the happy one, so to see her mean and grumpy, I just couldn't allow it." Twilight lightly tickled Pinkie's tummy, making her laugh even more. "I don't care if Heheheel's controlling her or not. A laughing Pinkie Pie is a normal Pinkie Pie in my books."

"You're all so funny! All of you! With your manes and your Cutie Marks, it's all hilarious!" Pinkie Pie said through her laughter as she looked at the rest of her friends.

"Maybe a bit too much?" Rarity watched Heheheel and Pinkie laughing together.

"Nope." Dash shook her head at the sight. "If Pinkie's laughing, she can keep going for a long, long, long time."

Eventually, everyone else in the throne room couldn't help but join in with the laughter. They weren't on their backs as Pinkie was, but they were still chuckling at what had happened.

"Hey, Whisper. I don't think I've seen this Yo-kai before." Twilight stopped in the middle of the road and pointed her watch at another Yo-kai. The creature looked perfectly like a dog with brown and green fur, but it had the face of a human male. "Care to fill me in?"

"Of course. That is Manjimutt." Whisper looked at the Yo-kai and stroked its' fur. "Unlike other Yo-kai, Manjimutt doesn't inspirit people, and instead just prowls the world looking for a job."

"Why's it got that weird face?" Twilight looked at Manjimutt's face as henstarted to chase his own tail.

"Have you ever seen a human before?" Whisper asked. "Skinny legs? Tiny nose? Sometimes even funny clothes?"

"Oh! You must mean those things on the other side of the portal!" Twilight realized exactly what Whisper was talking about. "Yes, I know what a human is now. They're those things that Sunset Shimmer's living with in the other world."

"Sunset Shimmer?" Whisper cocked a brow.

"It's a long story. I'll be happy to tell you once we get back to the castle." Twilight smiled again. "But right now, I think we should definitely make friends with Manjimutt. It'd be great to have a dog as one of our friends! Well, technically half-dog half-human, but it's still the same thing."

Twilight walked up to Manjimutt and slowly raised her hoof to greet him. "Hello there."

"Hi." Manjimutt waved at Twilight. "Who are you?"

"My name's Twilight Sparkle and this is—"

"Whisper?" Manjimutt recognized Whisper immediately and walked up to him. "Hey! Where've you been you sly devil, you?" He chuckled as he came over to Whisper and noogied his head. "It's been a long time, hasn't it?"

"Why yes, yes it has, Manjimutt." Whisper stopped the dog-man from noogieing him. "Are you still looking for a job?"

"Well yes, but most of these ponies don't really want a dog as their employee." Manjimutt looked at the different stalls and shops in Ponyville. "Figures. I'd probably get hair in most of their products anyway, knowing me."

"Aww, don't give up hope, Manjimutt." Twilight kneeled down and gave the dog a small back rub. "I'm sure that there's a place for you right here in Ponyville somewhere."

"Yeah, well it's not just a job I'm after." He used his back left paw to tap the ground. "I'm also looking for a place to stay outside of the Yo-kai World, and I was just counting my money for a house when all of a sudden, I was ambushed by a trio of Roughraff." He shook his head. "I could've taken them one on one, no problem, but they all attacked at once, and it just wasn't fair."

"Roughraff WOULD do that, wouldn't he?" Whisper shook his head and scoffed. "Honestly, it's bad enough that one was involved in this, but three at once just seems mean."

"Well, don't worry about a thing, Manjimutt. I'll find those Roughraff and give them a piece of my mind." Twilight slammed her hooves together and gritted her teeth. "Do you know where they are now?"

"Well, the last time I met them, I heard them saying that they were going to 'hang out' at the park." He flexed his paws to emphasise what the Roughraff meant. "We should go there now, to stop them from getting away."

"Good idea." Twilight began to walk away with Manjimutt and Whisper right behind her. "You stay with me, Manjimutt, and I promise I'll get your wallet back."

"Are you sure that you know what you're doing, Twilight?" Whisper lightly tapped her shoulders. "Roughraff is a cruel and nasty Yo-kai. Imagine the worst school bully you've ever had, multiply that by ten, and that's him in a nutshell."

"I could tell just from the name alone, Whisper." Twilight sighed as she looked at her Yo-kai Medallium again. "If anything goes wrong, I have five Yo-kai on standby to slap some sense into those Roughraff."

"Well, alright. But I'm not going to be responsible for what happens if Roughraff inspirits you or Manjimutt." Whisper crossed his arms as the group approached the park.

"We're here." Manjimutt began to look around at the different ponies, objects, and plants that were laid all across the green hills and dirt roads. He got up on his hind legs and used his front left paw to block out the sunlight streaking onto his face. "Be sure to watch out for a green Yo-kai with an orange pompadour haircut. That's what Roughraff looks like."

"Twilight. You might need the Yo-kai Watch for this." Whisper saw how much stuff was in the park and pointed to the watch. "I forgot to mention that Yo-kai can also transform into different objects and blend in with the real world."

"So they're like Changelings?" Twilight flipped the lens up and began searching. "Alright. Let's see what we have here..."

Twilight looked at each and every tree, blade of grass, pony, park bench, and flower that she could find in an attempt to find the Roughraff. Unfortunately, all of her searching turned out to be fruitless as the watch had not lit up once in her attempts.

"Darn! They must've got away." Twilight hung her head and stomped the ground as she closed the lens. "There's no Roughraff here, Manjimutt. Sorry about that."

"No. They're definitely here." Manjimutt stepped around Twilight and began sniffing the air. "I can smell the scent of delinquency somewhere in this park."

"Manjimutt has an enhanced perception of smell, Twilight," said Whisper. "He can detect a Yo-kai, person, or anything else from a mile away at least."

"There are three Roughraff here all gathered together." Manjimutt walked along the road, sniffing out the Yo-kai every step of the way. "The reason that you couldn't see them was because they decided to hide in the trees."

"You can tell that from smell alone?" Twilight's eyes went wide.

"Yep. I also smell that they're eating candy bars and using hairspray." He looked back and gave Twilight a thumbs up gesture. "No doubt that they're going to litter with the cans and wrappers once they're done..."

"Well, where are they now?" Twilight asked.

"I can smell that they're moving through the trees towards a trio of children." Manjimutt ran through the park to try and follow the scent of the Roughraff. "Probably going to use them to cause even more trouble." All of a sudden, he felt a new smell and shivered. "Twilight. Not to worry you or anything, but I can also smell an inspiriting flame."

"What?!" Twilight ran as fast as her hooves could carry her and opened her wings out wide. "We've gotta hurry! Get on my back!"

Manjimutt didn't even have time to respond as he was lifted onto Twilight's back by her magic. He simply held onto the flying pony and held his head out to the side, letting the air slam into his face and blow his lips back, just like an actual dog looking out of a car.

"There!" I can see them!" Manjimutt yelled and pointed out to the bridge where three fillies were standing there with purple flames around them.

"The Cutie Mark Crusaders?" Twilight grimaced at the thought of the three fillies being mean troublemakers. "Ooh, I'm gonna wrap my hooves around Roughraff's neck so hard..."

"Save the violent thoughts for later, Twilight." Whisper grabbed her shoulders, making her stop in mid-air. "For now, use the Yo-kai Watch to expose Roughraff. Then you have the usual negotiation or confrontation deal."

Wasting no time, Twilight flipped up the lens of the Yo-kai Watch and pointed it at the Cutie Mark Crusaders. In seconds, the three Roughraff appeared next to them. One sitting on Applebloom's back, another leaning on Sweetie Belle's mane, and the third one drinking soda and throwing it away as it stood next to Scootaloo.

"Roughraff! Stop this at once!" Whisper yelled at the top of his voice to the three Yo-kai.

"Hey guys. Look at that." One of the Roughraff pointed at Whisper and Twilight. "Some dorky poached egg is telling us what to do."

The three Roughraff merely shared laughter as they watched Twilight and Whisper both grit their teeth and crack their knuckles and hooves.

"Confrontation." Twilight and Whisper both said together as Twilight opened the Yo-kai Medallium.

But before Twilight could even pick a medal out of the book, Sweetie Belle leapt up and snatched it out of Twilight's hooves.

"Hey! That's mine!" Twilight was flabbergasted at Sweetie Belle's actions.

"Nope. It's ours now." Sweetie made a menacing look at Twilight and looked at her fellow crusaders. "And we're not giving it back, no way, no how!"

"Give. Me. That. Book. Now!" Twilight landed and marched up to the three fillies with fire in her eyes.

"Keepaway!" Scootaloo called, as Sweetie tossed her the Medallium.

Twilight ran over to Scootaloo, who threw the book to Applebloom, who then sent it to Sweetie as she got close, and then caught it again as she tried to grab it in mid-air. With every missed catch, Twilight's teeth gnashed together as she looked at the Roughraff riding on the backs of the fillies, using jockey whips to make them run faster.

"Giddyup, little ponies!" One Roughraff grabbed onto Scootaloo's muzzle and used it like reins.

"Yeehaw!" Another one cried out as it spun its' whip in the air.

"I'm the roughest, toughest, meanest cowboy in the whole wild west!" The third Roughraff drove Applebloom towards Applejack and swiftly stole her hat.

"Hey!" Applejack chased after the ponies.

"Stop those Roughraff!" Twilight called as she ran through the town with the CMCs having a commanding lead, with her, Applejack, Manjimutt, and Whisper just trailing behind.

"You know what's going on, Twilight?" Applejack turned towards her while still pursing the fillies. "Why are the Crusaders runnin' like this?"

"A trio of bad Yo-kai known as Roughraff have inspirited the fillies, turning them into mean and nasty troublemakers," Twilight explained. "They stole my Yo-kai Medallium."

"And my wallet!" Manjimutt yipped from Twilight's back.

"And my sanity!" Whisper wildly flailed his arms.

"I'm not gonna stop until I get back what I deserve!" All three of them said together.

"Well, I'd be glad to help out." Applejack lowered her brows and pulled out a lasso. "Any feller that thinks they can steal my hat and get away with it has got another thing coming!"

"She's got a rope!" The Roughraff with the hat warned his friends. "Split up!"

And with that, the three fillies jumped to each side to avoid Applejack's rope. They then dispersed into three different streets, each carrying a different item. Sweetie Belle had the Yo-kai Medallium, while Applejack's hat was travelling with Applebloom.

"Darnit!" Applejack growled as she chased after Applebloom.

"Give me back that book, Sweetie Belle!" Twilight galloped after the white filly so fast that she accidentally sent Manjimutt hurtling right onto Scootaloo.

The three chasers ran after their targets, with Whisper flying overhead to get a bird's eye view of the action. "This should be interesting..."

Author's Notes:

The whole thing involving Manjimutt and Roughraff will continue in the next chapter, just in case you're wondering, so be sure to stay tuned to that. I'm so glad to be getting out of Scotland and back home in a few days too, since I'll have access to my PC again once I'm back. And with that, I should be able to bust out chapters of this, and my other stories more often.

I also strongly recommend upvoting this story if you like it so far, as I feel that upvotes have much more of an impact and get my story out there easier, and attract a wider audience. And as always, make sure that you leave your comments down below and comment on what you liked so far, what you think could change, and some ideas for upcoming Yo-kai and who they inspirit.

See you soon.
