Happy Halloween everyone! Welcome to another yearly Halloween fic from me. This one is going to be a lot darker and more serious than any of my previous Horror fics that you've seen, and it's also going to be pretty long too, about 24-28 chapters. This story was inspired by "Shadow of Doubt" by AdmiralBobbery, "Death is But a Game" by BoomShroom, and the TV show "Pretty Little Liars."

Cast: Mario, Luigi, Yoshi, Birdo, Peach, Daisy, Pauline, Rosalina, Wario, Waluigi, Toad, Toadette, DK, Diddy, Dixie, Kooper, Goombella, Koops, Vivian, Bobbery, Count Bleck, Nastasia, Dimentio

I may or may not add one more character as the story goes on, but other than that, no more characters will appear.

The following story is rated T for language, violence, and disturbing scenes.

It was Halloween night and Princess Peach was holding a costume party at her castle. Dance music was blasting, people were getting drunk, food and drinks were thrown everywhere...it was definitely a disaster.

"HEY! Don't you dare knock that vase over! That thing cost me 200 coins and I do NOT want to get a replacement!" yelled Peach at a wasted partygoer who was dancing pretty extremely right next to her tall, ceramic blue vase.

Vivian walked towards Peach, lightly pushing various people out of the way due to how crowded it was. "Peach, this party is getting completely out of control! I told you it was a bad idea to bring a bunch of Tequila here!"

"I know, I know! But I just wanted one of my parties to be exciting for once. You have to admit, they're usually so dull and slower paced...which I'm definitely preferring now over this mess! I'm so glad Mario and Luigi aren't here to see this chaos...I bet they're having loads of fun in Isle Delfino..." Peach shook her head, definitely regretting even throwing the party in the first place.

"And with parties like these, you just KNOW there's gonna be a good chance a fight will be started. We need to send these people home now before someone does something incredibly dangerous and we'll have to pay the price for it!" yelled Vivian, very concerned for the princess' safety and for the castle as well.

Peach was about to respond, that is, until Rosalina ran up to the both of them in a state of panic.

"Have you guys seen Daisy anywhere!? She told me she had to go to the bathroom so I said I would wait for her, but that was 20 minutes ago! I've checked every bathroom I could in the castle but all of them were empty. I even texted her but I've got no response yet..." explained Rosalina with a very worried expression. She was secretly fearing that some drunk bastard took her against her will and went into one of the bedrooms.

"Oh god, she wasn't drinking a lot, was she? She probably passed out in some random bedroom..." sighed Peach, already tired of this damn party.

"I-I don't think she was. But we need to find her now! Anything could happen to her..." begged Rosalina.

"Okay okay, we'll look for her together. Peach, why don't you go check your room since if Daisy really is drunk, then that might be the first place she'll go to be at," suggested Vivian and the girls walked off to start the search elsewhere.

"Ugh, I am SO throwing invitation-only parties from now on..." groaned Peach and went upstairs.

"Yoshi, come on, let's get going. This is too messy for my tastes, especially now that I've seen that couple on the couch literally stick their tongues down each other's throats!" yelled Birdo.

"Ugh...can you...drive, Birdo? I think I might've...taken in too much of that sweet Tequila..." groaned the dinosaur, holding his stomach.

"Oh you've gotta be kidding me! Yoshi, what the hell did I tell you about drinking too much alcohol!? You do realize you're gonna have a colossal headache in the morning, right?" Birdo shook her head, especially after warning him multiple times about not taking in too much alcohol.

"I know, but...Tequila...so...damn good...OH GOD!" Yoshi suddenly covered his mouth and ran towards the bathroom like his life depended on it.

Birdo sighed in frustration, grabbed her purse, and began to head out until she bumped into a familiar person.

"OOH! Oh, I terribly apologize for...Birdo! What a pleasant surprise it is running in to you here! How have you been? Are you here all by your lonesome?" said the one and only Dimentio in his annoying and demeaning tone.

"DIMENTIO!? What the hell are you doing here?" asked Birdo in total surprise. She never thought that the jester of all people would want to attend some random wild party.

"I came here to meet someone very close to me. Why do you ask? Is it that important to know why I, Dimentio, Master of dimensions and pleaser of crowds, am here attending this disastrous party?" teased Dimentio with a wink.

"Yes it is important actually, because whenever you're around, trouble always happens! I know about all the crap you did a long time ago so don't think I'm gonna let you pull off another one of your stupid tricks," yelled Birdo, ready to smackdown this jerk.

"Oh just piper down already. Save your wrath for something that's ACTUALLY threatening," the jester sighed, rolled his eyes, and walked off into the crowd.

"WOAH! WATCH IT!" screamed Toadette as she barely dodged a thrown plastic water bottle.

"Ugh, whose brilliant idea was it come to this annoying party? It's full of idiots that just want to get wasted and have a one night stand. We're too good for this, sis. We are out of here," grunted Toad in frustration.

"Err it was technically Peach's idea to come here since she said it would be a fun and safe time...both of which are not happening right now! Let me go get my sweater and then we'll go," replied Toadette and attempted to tread through the loud and obnoxious party people. As she was making her way, she saw Dixie and Diddy who both looked like they were in the middle of an argument.

"I heard everything earlier today when you were talking to Toadette at the house! How the hell could you do this to me, Dixie!? I trusted you! I thought you loved me!" yelled Diddy, who was starting to sob.

"DIDDY, YOU'RE NOT LISTENING TO ME! YOU DON'T KNOW THE WHOLE STORY! And I do love you with all my heart! I just...if I tell you why it happened in the first place...it will kill you...but it wasn't my fault! I was...I was..." Dixie struggled to get her words out without breaking down in tears.

"It will kill me? Huh...it already did, Dixie. I am done with you," Diddy angrily shook his head and stomped upstairs while Dixie buried her face in her hands.

"Oh god...I knew this was going to happen sooner or later..." sighed Toadette and was about to go and comfort Dixie until she saw DK nearby, glaring right at her.

"What the hell...?"

"YOU BITCH!" yelled a familiar female voice. Right after that, there was a bunch of screams as Goombella tumbled down the stairs.

"IF YOU EVER GET CLOSE TO MY MAN AGAIN, I WILL BEAT THE SHIT OUT OF YOU!" roared a drunken Pauline who had pushed the poor goomba gal down.

"Ooooooookay then that's more than enough drinks for one night! Pauline, let's get out of here unless you want your ass arrested...AGAIN!" yelled Waluigi who was in shock at the violent act that occurred. He grabbed Pauline and pulled her out of there before anyone could do anything.

Koops and Kooper ran over to Goombella's aid and helped her up.

"My god, Goombella! Are you alright!? You're not bleeding, are you!?" asked Kooper.

"Ugh...my head is killing me...what the hell was that chick's problem though!? I was just telling Waluigi something! It's not like I was hitting on him...not like I would ever do that in a million years anyways because ew!" yelled Goombella who luckily didn't have much physical damage to her.

"Well it's over with now, but we should get out of here in case anything more, um, dangerous happens because this party is getting out of control," suggested Koops and the two dragged her out of there.

Meanwhile, Wario came out of the upstairs bathroom, tipsy as all hell and his vision was slightly blurred.

"Ah shit...BURP! Can...can someone help get me down the...thing pleeeaaase? Waluigi? Are ya here? Helloooooooooooooo!?" he called out and slurred his words as he attempted to walk down the hallway without stumbling over. He then saw a familiar person approach him.

"Oh! Daisy! That you? Yes? No? Yes? Maybe so? Well whatever! Help me down those goddamn stairs so my stupid brother can take me home..." he growled and Daisy took him along and carefully led him down the stairs then to the outside.

Peach opened the door to her bedroom and was surprised to see Diddy of all people to be in there. He was talking to someone on his cellphone while crying uncontrollably.

"THIS IS ALL YOUR FUCKING FAULT! My life has been absolute hell ever since I met you and...what? You want me to do WHAT!? NO! SCREW THAT! I AM DONE HIDING SECRETS! LOOK AT WHERE IT'S BROUGHT ME! I WANT OUT!" he screamed.

"Diddy? What's going on? What are you doing here?" asked Peach in concern and slight fear since she had never seen the monkey so emotional before.

"P-PEACH!" he shrieked and accidentally dropped his phone. "I...I'm...um...please...leave me alone...I just...wanna be alone..."

The princess wanted to ask why but she was afraid he would explode at her so she quickly nodded and closed the door.

"Wow...that was actually a bit freaky...who the heck was he talking to?" she asked to herself.

Meanwhile, as Vivian was just about to give up on the search for Daisy, she saw her come into the castle.

"Oh Daisy! Where were you? Me, Rosalina, and Peach were looking all over for you! We were worried you had gotten wasted and passed out or something!" the shadow siren yelled in relief.

"Oh I was just talking to Luigi on the phone in one of the rooms upstairs because it's so goddamn loud in here. I was also taking Wario to his brother's car because one more drink, and he would die of alcohol poisoning!" she explained and laughed a little.

"Alright then...well, I guess now we just find Rosalina and Peach so they can see you're okay. We also need to find a way to get everyone out of here because this place is getting trashed by the second!" exclaimed Vivian.

Right after she said that, the electricity shut off along with the music from the TV which made the partygoers groan in disappointment and some even screamed.

"Everyone! It seems as if there has been some kind of power outage so I need you all to exit the castle so no one gets, um, lost and...hurt?" shouted Toad, trying to find any kind of legit excuse to get these people the hell out of there already. But surprisingly, they all listened and walked out of the castle, leaving some of the remaining characters behind.

"Um wow. Okay then. That was helpful yet coincidental. How the hell did the electricity just go off like that?" Birdo asked.

"Oh I just switched off the fusebox in the basement. I could tell Peach was getting pretty tired of the insanity that was happening so I had to do something to help her out before me and Toadette left," explained Toad.

"Why thank you, Toad! I was actually getting ready to call the police to come over here since I was running out of options on what to do about those people..." Peach spoke as she was heard walking to the living room due to her heels.

"So, uhh, anyone wanna go down to the spooky, dark basement and turn all the lights back on?" asked Daisy.

"Give me a flashlight and I'll go. We certainly won't be able to clean up the place in the dark," said Rosalina.

"Ugh, I'm afraid to see what this place will look like once the lights turn back on!" said Toadette.

"Here Rosalina, follow me into the kitchen and I'll hand you the flashlight then I'll lead you to where the basement is," ordered Peach and the two princesses left to the kitchen.

"Okay it's getting awkward to be standing around in the dark like this so why don't we all just go outside till the lights come back on?" suggested Birdo and everyone immediately agreed with a "Yeah" or "Yes please!".

The remaining characters that were inside, besides Peach and Rosalina, exited and were met with Goombella, Koops, and Kooper who were standing right outside, looking concerned. They also saw the partygoers talking amongst themselves and scoffing at the now ruined party so they all got in their cars and headed off.

"Hey is everything alright? We were just about to get Goombella home but then we saw the lights shut off and thought something bad might've happened..." Kooper asked.

"No no it's fine, little devious Toad right here shut off the fusebox so he could get everyone out of there because it was really getting out of control," said Daisy while Toad smirked at her 'compliment.'

"Oh! Dixie! I didn't know you were still with us! Is everything okay?" asked Toad, noticing that the monkey gal looked upset.

"I...um...I'll tell it to you later. I just wanna go home and sleep..." she replied, not even bothering to look at him.

"Oh god, you and Diddy got in a fight, didn't you? Don't tell me you two broke up!" groaned Daisy and felt bad for her. Dixie wiped her eyes and just gave a shrug.

Right after that, DK suddenly came out of the castle with his arms crossed and held a serious expression.

"It's a bit funny how two people can be so close and then, suddenly, there's just one little thing that ends it all, don't you agree Toadette?" the ape asked in a way no one's ever heard him speak before. Everyone gave him a look of confusion.

"Uhhh...y-y-y-yeah, sure...I guess..." replied Toadette nervously while shifting her eyes.

"Hey, isn't that Waluigi's car over there? Why is it empty? Didn't the brothers and Pauline leave to go home in it?" asked Vivian, pointing to the purple Mustang, the only car that was now left on the grounds besides the remaining people.

"Yeah that is a bit odd. Did they go back inside? Perhaps they're lost in the dark?" suggested Birdo. Everyone else shrugged, not having the faintest idea since none of them saw the three after they exited the castle.

The lights turned back on and everyone gave a sigh of relief.

"Finally! Now let's get back inside and see how trashed the place is..." said Toad, not looking forward to cleaning up. Everyone went inside and groaned at the messes that were made. Cans, food, stains, glass, and anything else you can think of were scattered all over the floor.

Peach and Rosalina made it back to the others.

"Well we got the lights back on successfully, but now we need to clean this place up...fun..." sighed Peach, already tired enough as it is.

"We'll help you clean up, Peach. It will be a bit quicker if we do and I'm sure all of us wouldn't want you stuck to deal with this all by yourself. Any objections?" asked Kooper and everyone shook their heads...except for one ape.

"Nah, you guys got this. I'm just gonna go home and pretend that I never went to this stupid party in the first place. Quit trying to make yourself appear 'cool' and 'not boring' by throwing these crazy parties, Peach, you're not fooling anyone," stated DK in anger and quickly walked out of the castle, leaving the others in surprise by his unusual attitude.

"Wow! What the hell is his problem!? He's been acting like that for a while now. Dixie, do you know?" asked Toad.

"...N...no...I don't...just forget him, it doesn't matter. Let's start cleaning up," said Dixie while rolling her eyes.

"Peach, don't listen to anything that jerk says. I don't know what his problem is, but he needs to not take it out on us," said Daisy.

The princess stood there for a few seconds with no response. Tonight was suppose to be a blast, but it turned out to be the complete opposite.

As everyone started to clean up, Birdo checked the bathroom to see if Yoshi was still in there. Thankfully, he was, but it looks like the poor dino fell asleep next to the toilet.

"Ugh...Yoshi...oh god, is that the smell of puke!? Come on you, you're laying on the couch, then I'm taking you home once we're done here..."

THE NEXT MORNING...

Peach opened her eyes. She was lying on her bed in her room. She sat up and looked over to find Daisy lying next to her, still sound asleep.

"Huh. I don't remember coming up here to go to sleep...I must've been really exhausted after cleaning the place up..." she said to herself and then looked over to her clock. It was 12:27 PM. Peach never woke up that late before so she must've gone to sleep a lot later than she thought.

"Perfect. Just perfect. It's already noon and I haven't even ate breakfast, taken a shower, brushed my teeth...ugh, I am so not looking forward to today. Daisy, come on, wake up. It's late," groaned Peach while nudging her best friend. Daisy grunted a little and slowly opened her eyes.

"Oh my god...I feel like I've been hit by a bus...did we get everything cleaned up last night?" the tomboy said while yawning and standing up.

"I think so. I'm guessing after we were done, everyone else just left and us two just randomly fell asleep on here. I honestly don't remember anything from last night after DK was being rude to me for no reason..." said Peach while stretching her body and yawning as well.

"DK was probably buzzed last night, so don't worry about it. He turns into a mega douche when he's drunk, remember?" recalled Daisy, who was looking in the mirror and made a disgusted expression at how messy she looked.

"I guess so...well, whatever. Let's go brush our teeth and get dressed, we need to make ourselves look decent for when Mario and Luigi come home from their vacation later on today," said Peach and walked over to her closet to pick out the clothes she would wear after her shower. She opened it and let out a shrill.

"Peach!? What is it!?" Daisy jumped at her scream and ran over to the closet.

"O-OH MY GOD! IT'S DIDDY!" yelled Peach and quickly backed away. Daisy saw what made Peach petrified.

It was Diddy lying against the wall with his throat slit.

EOC.

So, even though Diddy is dead, he is still going to play an extremely important part in this story, from now until the very end. Also, the rest of the characters will appear next chapter. I'm not going to ask you all who do you think committed the crime, because it's just the first chapter and there will be many clues and mysteries unfurling as the story goes on.

And for those of you who are still waiting on a new chapter of Mario Party Deluxe, don't worry, for I will start writing it tonight and hope to get it uploaded before the 6th!
