Episode One: Murder at Six o'Clock

Author's Note:*Ahem* Yes, this will be a crossover between Case Closed and My Little Pony, where the main characters from Case Closed (Basically Conan/Jimmy, Rachel, Richard, and a few others) will be in ponysonas and in Equestria. Oh, the paragraphs in italics are Jimmy's thoughts, since the story will be more focused on him (And when it says "Conan says" or "Conan *did this*", it's still Jimmy. Remember that, mate). Oh, 'yknow, this will start during the time right after Jimmy gets poisoned and turns into a kid.

Episode 1: Murder at 6 o'clock

Why me...

"OOOOoooo! Hey Rachel! Who's the new kid?! I know every pony here, but I sure don't know this little colt!" A certain pink pony bubbled with excitement in the middle of the Ponyville town square. The pink pony had been talking with Rachel for a full twenty minutes until she actually noticed Conan, which was only when he yawned.

"Oh, this is Conan. He's the professor's nephew." Rachel replied.

"WHOA! I never knew we had a professor- no wait, now I remember! Yeah, the professor! He never told me he had a nephew! Where ya from, kid?!"

"uh, I'm from Manehatten," Conan said, thinking of the first thing that came to his mind. With a voice so innocent and childlike, you'd never expect him to actually be a seventeen year old, rather than being the eight year old he appearsto be.

"Coolio! Isn't that where all the big shot ponies are? Let me tell ya, my family almost move there when we were little, but with us being on a rock farm, we never had enough money! I always wondered why we even had farm rocks. I mean hel-loooo, they're rocks! They can't grow! So why did we have a rock farm?! That idea might have been crazier than me! Oops, I shouldn't say that! Tee hee, nothings crazier than me!"

At least you're right about that...

"Hey Conan. How about you spend the day with Pinkie Pie?" Rachel suggested.

Rachel, I've known you know for seventeen years, and what you're suggesting is by far the worst idea you've ever had.

"OOOOooo! Yeah! That'll be so fun! Can I take him to Sugarcube Corner so he can play with the twins and make some, u-uh, Cupcakes?" Pinkie said as she bounced in place.

"Well Conan? Want to spend the day with Pinkie Pie?" Rachel asked to confirm.

"Sure, OK," Conan said, knowing that he'd be suspicious if he said no.

"YAY! C'mon Conan! We've got a day of fun ahead of us!" Pinkie nearly yelled as she grabbed Conan and brought him with her to Sugarcube Corner.

"Bring him back by six!" Rachel yelled.

"This is gonna be FUN FUN FUN!" Pinkie giggled as she and Conan entered Sugarcube Corner.

"So what 'FUN FUN FUN' thing will we be doing miss?" Conan asked.

"Hmm, first, we play with the Cake twins. Oh, they are so adorable! You should see them, one's a Pegasus named Pound Cake with too much energy so he can fly a whole lot, which, to me, is really unfair to Scootaloo, since she can't fly. The other filly's a girl Unicorn named Pumpkin Cake and she just loves loves loves her rubber chicken doll. After we play with them, we'll watch some movies! Maybe Tangled or, no, wait, The Nutty Professor. Strangely, the movies don't have ponies as the main character: They're some kind of strange species that know one knows. But anyways, after that, we'll play the game of Clue. Oh, it's my favorite game! You know, murder mysteries? Sometimes they'll never get the right suspect as the killer, which is what makes it fun: Er, you've, uh, gotta try some more to catch the murderer, yeah, that's it. Then we'll bake some cupcakes made from Rainbow Dash! Rainbow Dash loves cupcakes, and so do I! I'm sure you do too! Then after that, it'd be time for you to leave... But then we'd play again tomorrow! That's the fun in it, isn't it?!"

Hold on! It sounded like her reasoning for liking Clue was another reason than what she suggested. And bake cupcakes from Rainbow Dash? I'll need to keep a close eye on this pony...

Too enveloped in his thoughts, Conan merely muttered. Pinkie took this as a yes.

"Squeee!" She squealed. "Alright! It's time for the twins first!"

The two walked over to a playpen where the twins were sleeping.

"Shouldn't we just leave them alone, Miss Pinkie? They're sleeping, after all," Conan suggested.

Pinkie turned around to Conan with a blazed and empty look in her eyes, like all the party had been sucked out of her and all that remained didn't even have a soul. Her hair became ever so slightly straighter, but not by much. "Why Conan... Don't you know it is rude to stop a plan when you are only the guest?" She said, her voice trailed with just a small hint of anger, but more along the lines of monotony.

This pony's crazy! I have to make sure she doesn't do anything to anyone... Or me.

"I'm sorry Pinkie. It won't happen again," Conan apologized.

"Well that's fine then Conan!" Pinkie accepted as she went back to normal.

Pinkie opened the playpen and nudged Pumpkin Cake. She stirred, but only a little.

"Wakey wakey, Pumpkin Cake," Pinkie said.

When Pumpkin heard that it was Pinkie's voice, she woke up immediately and woke up Pound Cake.

"Oki doki loki! Let's watch The Nutty Professor!" Pinkie said as she walked towards the TV room.

Wait, that's what she means by playing with the twins?

"Why didn't we play with the twins some more? You just woke them up for nothing!" Conan asked as he caught up with Pinkie.

Pinkie stopped suddenly, almost making Conan run into her. She turned around with the same expression as last time. "There's a reason for everything Jimmy..." She turned back around and bounced over to the TV room.

H-how did she...? But I never told anyone yet! It's only been less than a day! How could Pinkie possibly know?!

An hour and a half later, after they had watched The Nutty Professor, Pinkie brought Conan in the kitchen.

"Now we're gonna make some ~cuuuuupcakes~!" Pinkie giggled. "~First you take a cup of flour, add it to the mix. Then you take a cup of sugar, add a bit of salt, just a pinch~"

Conan noticed Pinkie's song, but she sung it too softly, so he couldn't even hear the words. "Miss Pinki-"

"Oh Conan, you can just call me Pinkie Pie! Or Pinkamena, or Pinkamena Diane Pie, or Diane, or Diane Pie, or Pie, or Pinkamena Diane, but I'd prefer it if you called me Pinkie." she said as she set up the bowls and ingredients necessary.

"uh, Pinkie? What was that song you were singing?"

"The Cupcakes song? Want me to teach it to ya?!" Pinkie offered, eager to start.

"Oh, no thanks, I-"

"NONSENSE! I'll still teach ya! Now then, ~first you take a cup of flour, add it to the mix~"

Conan searched for the cup of flour, but to no avail. Pinkie helped as she grabbed the bag which was hidden behind everything else. Due to Conan's small stature, it was quite hard to find it.

"~Then you take a cup of sugar, add a bit of salt, just a pinch.~"

This time, Conan finds the sugar and salt and adds it to the mix.

"~Baking these treats is such a cinch add a teaspoon of vanilla.~"

Pinkie grabbed the vanilla.

"~ Add a little more, and you count to four, and you never get your fill of... Cupcakes! So sweet and tasty! Cupcakes! Don't be too hasty! Cupcakes! Cupcakes, cupcakes, CUPCAKES!~" After putting in the necessary ingredients, she turned to Conan. "So Conan, want to do the honors and put in the special ingredient?"

Before Conan could say anything, the clock chimed. It was six o'clock.

Thank god...

"Aw... Well, bye bye Conan!" Pinkie said, pushing him out the door, then shutting it. After blinking over how fast that was, Conan decided to go back to Rachel's place.

"Oh, Conan, you're back just in time," Rachel said as Conan walked through the door. He didn't answer back. He was too tired and only wanted some sleep.

The next day:

Conan woke up to a crashing sound. On instinct, he thought Rachel was hurt, so he scurried down the stairs into the living room.

"Rachel, Rachel!" Conan yelled.

"Oh, did you hear that crashing sound too?" Rachel asked as she looked through the window. "It came from outside. I'm just surprised my dad didn't wake up from it," she chuckled. Conan looked through the window and saw a carriage wreck just a mere few yards from their house. Police were already on the scene. Having a feeling that Pinkie had something to do with it, since Sugarcube Corner was right across from them and therefore next to the wreckage, he ran outside onto the wreckage.

"Who let a little colt here?" A large police stallion snorted. He was answered with a wave of "not me"s from other police stallions. "You heard 'em kid. Get on out of here."

Conan grunted and walked off, but he could still hear two police stallions discussing the event.

"One injured, three dead. A Pegasus foal, a Unicorn mare, and a Earth Pony stallion. The filly Unicorn was rushed to the ER. She'll live."

"That's not all Butch. There was a teenage mare in one of the carriages, but there's no trace of her. I think her name's Minuette?"

"That's weird..."

Disappearances? I've a feeling that Pinkie's responsible, but maybe I need to ask around first to get some better info on Pinkie...

"Excuse me, but where's Miss Sparkle?" Conan asked.

"She's upstairs in the library," a green dragon replied.

"uh, can I talk to her?" he asked.

"Sure. Just go up the stairs and you'll see her sorting books... which was my job but I guess no one cares."

Conan went up the stairs and, as expected, saw a purple unicorn putting books in order. "Twilight Sparkle?"

"Oh, who might you be?" she asked, turning towards Conan.

"My name's Conan Edogawa," he replied.

"That's a strange pony name."

"Can you tell me about a mare named Pinkie Pie?"

"Oh..."

"D-did I do something wrong?"

"No, it's quite alright," she replied with a forced smile. "Pinkie is, well, a party pony. Ponies only love her parties in small doses. To put it bluntly, she's kind of crazy, but it's the kind of crazy that you just can't hate," she chuckled a bit. "But... I don't think anypony else knows this... But Pinkie might have split personality."

I guess a split personality would explain what happened last night, but it still doesn't explain how she knew I'm really Jimmy.

"Oh, ha ha, you're just a colt. I wouldn't expect you to know what a split personality is," she replied. "It's where one pony acts in two different ways, or two ponies in one body, so to speak. I should warn you right now Conan, if you ever break a Pinkie promise, that's when her bad personality comes out. Never break a Pinkie promise."

"O-ok..."

"I'm sorry. I shouldn't have scared you like that. It's really easy to not break a Pinkie Promise, so you're most likely fine." Twilight reassured.

"OK, thank you!" Conan replied as he left.

Maybe the mare that disappeared broke a Pinkie Promise? I don't know. Equestria doesn't have many crimes, so you wouldn't suspect somepony right off the bat. But there's no mystery Jimmy Kudo can't solve! He thought as he walked along the street from Twilight's place. Let's see... the evidence so far is that a mare disappeared. No prints, nothing else. Whoever it is, the kidnapper's smart.

"Hiya Jimmy!"

"WAH!" Conan screeched, falling headfirst to the ground. He got back up while rubbing his head. "Argh... Don't do that..." He looked up and saw the same pink pony from yesterday. "Oh, hi Pinkie! uh... Why do you keep calling me Jimmy? I'm Conan."

"You're a silly filly, ya know that?!" she giggled.

Conan was about to say something, but was cut off by ambulance and police sirens passing by him. He ran off and followed them, leaving Pinkie to stand there.

"We've found the body!" A police stallion yelled to the others. Conan got there just in time. He hid behind a building and watched the entire thing.

"It looks like the mare committed suicide. She was found dead behind the school building with a gun in her head and a suicide note next to her. She hasn't undergone rigor mortis yet, so I'd say she's been dead for merely a few minutes." One stallion told the other.

"Poor Minuette... She was my daughter's best friend..." The other replied.

"Oh suck it up, Buttercup."

"Hey, shut up Rocky. This is actually really sad."

"Oh can it Butch. Minuette was pretty rude to many other mares, especially that Derpy Hooves. It ain't like they're gonna miss her." Rocky said.

"But it's still sad. I mean, somepony must have been even ruder to her if she were to commit suicide."

How idiotic are they? There's evidence that it was a murder, not a suicide. If it was a suicide, there'd be burnt skin where she supposedly shot herself. But there's not. It'd be impossible to commit suicide without some burnt skin where they shot themself.

"Conan Edogawa!" A voice came from behind. He turned around and found out it was Rachel, with her eyes glaring. "You shouldn't have run off like that!"

"I'm sorry Rachel..."

"You could've gotten hurt!" She bent down to eye level with him. "Look, I know you want to play detective, but you're better off just letting my dad or the police take care of it. They've already ruled it as a suicide."

But it's not! Someone murdered that mare! The question is who... Of course!

"OK Rachel... Hey Rachel? Can I go to Derpy's house? Pinkie said that Derpy would teach me how to make muffins," Conan lied, trying to come up with an excuse to go over and interrogate Derpy.

"I guess so. But be back by six, and don't go back to the crime scene. Oh, and don't call her Derpy. She hates that. She likes being called Ditzy, OK?" Rachel walked back to her house.

Conan rang the doorbell, and a grey mare answered it. "Oh, hello there young foal. Who might you be?"

"Conan Edogawa."

"Strange name. My name's Ditzy. Ditzy Doo," She reached a hoof out, and Conan gave her a hoofshake. "Come on in. I've got some muffins set out. You're more than welcome to have some."

He entered her dwelling and sat down on a couch in her living room.

"Miss Ditzy? Did you hear about that death of a mare today?"

"Minuette? Oh, yeah. That's just so sad... I can't believe someone murdered her... I mean, she had so much potential in life! I guess these things happen..." She sighed as she sat down on a chair opposite of Conan.

But they ruled it as a suicide! It's quite obvious who the murderer is... But if I accuse her now, with no one else here, things could get ugly...

"Oh, hehe, look at the time! I gotta get going!" Conan stuttered.

"OK, bye bye Conan!"

"Rachel, Rachel!" He yelled as he entered the house.

"Oh? What is it Conan?"

"I went to Ditzy's, and she told me they ruled the death of the mare as a murder, but they said it was a suicide!" Conan replied, trying to sound as childlike as possible so he wouldn't blow his cover.

"Huh... I'll tell my dad about it when he wakes up --- still can't believe he's still asleep --- and he'll look into it, OK?"

Conan smiled.

An hour later, Ditzy Doo was caught and charged for the murder of Minuette. She confessed that it was because Minuette made fun of her for having wall eyes.

Conan, looking at the scene in which Ditzy was being caught, was relieved. Another case solved thanks to detective Jimmy Kudo.

Wait a minute... What about Pinkie? Sure she must have done something...

"Hiya Conan!" Pinkie's voice yelled as Pinkie was somehow right behind Conan.

"I said to stop that!" Conan said.

"Oki Doki Loki!"

Conan walked off as Pinkie bounced back into Sugarcube Corner. She went in the basement, and her posture became different. Her hair was sleek and straight as her entire being turned a darker shade of pink.

"You're smart Jimmy Kudo... But I'm smarter..."

Episode Two: Angel Abduction (Pt 1)

Episode Two: Angel Abduction

"Just calm down ma'am," a police stallion reassured the sniveling Pegasus.

"CALM?! H-how can I b-be C-CALM when A-Angel's g-gone m-missing!" The cream colored Pegasus cried.

"She's got a point Butch," Rocky, the other police stallion pointed out.

"Shut up," said Butch. He turned back to the Pegasus. "What's your name, madam?"

"F-F-Fluttershy..." The Pegasus with bright pink hair muttered as she tried to back away.

"And what does Angel look like so that we can give a missing ponies report?" asked Rocky.

"H-he's a bunny w-who's a-about one f-foot tall... w-with beady b-black eyes... and he's v-very picky..." She replied

"Got it. We'll send a report on it while a detective comes in. Have a good day ma'am," Rocky said as he and Butch left. One they left the building, Butch gave him a good hit on his head.

"OW. What was THAT for?!" Rocky fumed.

"'Have a good day ma'am'?! You IDIOT! Her rabbit friend got kidnapped and you want her to have a good day?!"

"Jesus, sorry."

"Better be..." Butch muttered under his breath.

Five minutes later, seven ponies arrived to the house: Conan, Richard, Rachel, and four other detective ponies. Richard, a stallion with a light tan coat and a brown mane and tail, walked in front of Fluttershy and knelt down. "Alright, first things first, what evidence lead you to believe he was kidnapped rather than running away?"

"W-well, Angel's room was cluttered up, but Angel always keeps his room tidy. And there was a ransom note on his bed," she replied, no longer stuttering, but still maintaining a softness in her voice.

Richard turned to the other detectives. "Search for clues."

The other detectives went to work as Richard did too. Conan, a white coated colt with a mane and tail that's a black color and who wears a blue suit with a red tie (The tie which enables him to mimic other people's voices) and glasses, walked towards Fluttershy, whom was sobbing as she was bent down on the floor.

"Miss?" Conan asked.

"Y-yes?"

"When did you last see Angel?"

"Just two hours ago: He was sleeping in his room..."

Conan looked at the window that was broken. Shards of glass were scattered on the ground outside.

"Fluttershy? Did you have your door locked?"

"Yes, until the police came. Why?"

Conan glanced at the door: It wasn't open. No forced entry via door, nothing. It ruled out Conan's second option, which must meant...

Someone from Fluttershy's place must have done it! If the kidnapper broke in, the shards would be on the floor. But they're outside!

"No reason!" Conan said as he walked away from Fluttershy. Just then, the door busted open, and a cyan Pegasus went inside Fluttershy's house.

"Hey! This is a crime scene! Get lost!" Richard yelled.

"Listen, I'm Fluttershy's friend, so I'm able to come in here, crime or not," She flicked her rainbow mane.

"Rainbow c-can come in..." Fluttershy said, joining in.

Rainbow stuck her tongue at Richard, making him furious. She noticed Conan, and rubbed his head. "Hi Conan. Pinkie's told me all 'bout you."

"T-that's cool, I guess," Conan said, putting his mane back in order.

Rainbow Dash turned to Fluttershy. "So what crime happened?"

"Oh it was horrible Dashie! Angel got kidnapped!"

"WHAT?! Nopony takes any of Fluttershy's animals!" Rainbow scowled.

Fluttershy turns to Conan. "Um, little colt? Would you like to help out and try to find Angel? The more help the better.... if that's OK with you..."

"Sure!"

"Hey, let's get Twilight here. She can be Sherlock and he can be Wattson," she teased, grabbing Conan's cheek.

"Um, Rainbow? I was just kidding. I doubt Conan, was it, can do it. I, I mean, a little kid like that just can't." She turned to Conan defensively. "I-I mean you can help if you want, b-but I don't think that will bring enough help..."

"But I want to play detective!" Conan argued, trying his best to act as childlike as possible.

Rainbow laughed. "Oh come on Fluttershy! Give a kid a chance. Sure, he might not be able to get Angel, but I bet Twilight could help him! Twilight's an egghead: She loves this kind of stuff."

To be honest, I'd rather be Sherlock... I can solve mysteries better than "Twilight".

"Hey, I'll go get Twi' right now!" Rainbow replied as she sped out through the open door.

"It's OK miss. I'll help you find your bunny." Conan reassured as he patted Fluttershy on the back.

Richard walked back to Fluttershy as he pushed Conan away. "Fluttershy? We've found some clues. It appears that the kidnapper is someone in this house."

Look at that. Richard may be able to solve this after all.

"Oh my. The only others who live in this house are my animals. Why would you assume that?" she asked.

"It's quite obvious, really. The window shards are outside. If a stranger broke in, the shards would be inside, but no! They're outside!" Richard concluded as he gave a proud look to himself.

"Sorry mister. But that doesn't prove anything."

"What?"

"That window had been broken for a week already... I didn't want to get cut with the shards, and no one would help, so I left it there..."

Right after Fluttershy finished, Rainbow Dash and Twilight appeared, with Twi' looking slightly dazed.

"How'd you get here so fast?" Conan asked.

"You're looking at the fasted flier in all of Equestria!" She boasted while Twilight murmured.

Richard merely rolled his eyes. He went upstairs to see what the ransom note had to say. As they did, Rachel, a slightly darker white coated Pegasus with a black mane and tail, came over. "Fluttershy? Do you want me to help you find Angel? I can give that kidnapper a good fight! I am, after all, an expert in Karate!" she boasted.

"It's alright Rachel. You don't have to if you don't want to... if that's OK with you, I mean..."

Twilight finally comes back to her senses after that fast trip. "Fluttershy, I'll help you find Angel."

"Oh thank you!"

Rainbow Dash sneer as she picked up Conan, whom was struggling from her grasp. "And Conan can be Wattson. BWAHAHA!"

Twilight studied Conan. "Oh. Didn't we meet yesterday or so? Anyway Conan, do you want to be a little junior detective?"

"Yeah!" Good God, what's with these ponies thinking I can't solve a mystery? Well, besides me being as an eight year old.

"Terrific!" Using her magic, she got out her Sherlock hat from her satchel she brought, as well as her bubble pipe. "Well then Conan, let's go get some clues!"

"Mind if I come along?" Rachel asked. "I don't really want to be alone with Rainbow and Fluttershy.

"Sure," replied Twilight.

The trio walked up the stairs to Angel's room. Upon arriving, they saw Richard... Asleep.

"Dad?" Rachel asked as she walked over to him. She turned him to his side and gasped.

"What?!" Conan almost yelled.

"Someone tranquilized my dad!" she panicked. A tranquilized dart was indeed in Richard's front hoof.

"Okay, no pony panic... We need to be calm. It's obvious the kidnapper's still here, so we'll need to search around. Rachel, you search downstairs with the other detectives and tell them that Richard's been tranquilized. Conan and I will look around upstairs." Twilight reasoned.

"Got it," said Rachel as she headed downstairs.

Now the two were alone with a sleeping Richard. "Hey Twilight?" Conan asked.

"Yes?"

"You know how I was asking about Pinkie Pie yesterday?"

"Yes?"

"Can you tell me some more?"

Twilight looked conflicted. "S-Sorry Conan. Not right now... Remember, we need to look for clues."

Conan sighed. He wasn't getting anywhere with finding out about Pinkie Pie... He went towards the random note while Twilight searched around and read it.

"I've kidnapped Angel."

That's not really enough help as to finding out the kidnapper. Why would they kidnap Angel without any claims for ransom or anything of the sorts? Maybe running a hoofprint test on the note could find the kidnapper. Maybe even searching for who's handwriting it is? The handwriting does look familiar...

Something fell to the ground in the next room. Conan ran as fast as he could and gasped at what he saw. There, slumped on the ground, was an unconscious Twilight, or so it seemed. He bent down to Twilight just to make sure she wasn't dead or anything. She was breathing, and her pulse was steady. She must have been tranquilized.

Footsteps entered the room, ever so slightly, but not soft enough for Conan not to hear. He turned around and screamed.
