Derpy arrives back at her house walk's in the door and start's thinking about other ponies who think they are better that her.
"So, who else think's that they are better than me? Let me think. Ah, I know, Sweetie Belle, I see her looking at me when I make mistake's, thinking that I am an idiot. Well im not, I'll show her..." Derpy said to herself.
Derpy stay's up all night making a deadly plan especially for Sweetie Belle. Meanwhile at the forest, at six O' clock in the morning, Apple Bloom, Sweetie Belle, Scootaloo and Apple Jack wake up.
"Good morning Apple Jack, you ready for the second day of the camping tri... Wait... What is that?" asked Scootaloo.
Scootaloo pick's up the note that Derpy wrote, unaware of who wrote it.
"What's that Scootaloo? It wasn't there last night." Apple Jack Said.
"It's a note. It say's:
Dear Scootaloo,
Since you are her biggest fan, I thought you should have this to remember her by.
Love from the mysterious insane mare.
Who is this mysterious insane mare?" asked Scootaloo.
Scootaloo pull's off the white sheet over Rainbow Dash's dead head.
"DEAR CELESTIA, WHAT HAPPENED TO RAINBOW DASH?!" screamed Scootaloo.
"ALL OF YOU, BEHIND ME NOW!" shouted Apple Jack.
The cutie mark crusader's ran behind Apple Jack. Scootaloo couldn't stop looking at the head, the more she looked, the bigger the tear was in her eye.
"Don't worry girl's, this is just a prank Rainbow Dash has pulled on us!" said Apple Jack.
"But I was her biggest fan, why would she pull a prank like this on me, that's not a prank, that's just being mean." said Scootaloo.
"I don't know. But she has taken it too far this time. Come on, pack your things. We're going to have a little chat with her." Apple Jack said furiously.
Apple Jack, Scootaloo, Apple Bloom and Sweetie Belle exit the forest and go to Rainbow Dash's house. Apple Jack knocks on the door.
"RAINBOW DASH! WE WANT A WORD WITH YOU!" shouted Apple Jack.
No pony answered. Apple Jack kept shouting. But still, No pony answered.
"Why is she not answering?" asked Apple Bloom.
"I don't know little sis, im going to see Twilight, see what she can make of this.
Apple Jack, Sweetie Belle, Scootaloo and Apple Bloom made their way to Twilights tree house. Apple Jack knocks on the door with her hoof. Twilight answers the door.
"Hi Apple Jack, how are you doing?" asked Twilight.
"Hi Twilight, I think Rainbow Dash has pulled a prank on us again but this time she's gone to far." said Apple Jack furiously.
"Why, what did she do?" asked Twilight curiously.
"She put a replica of her head to make it look like she's been killed by some pony and put it at Scootaloo's tent at our campsite to scare us." said Apple Jack.
"I know Rainbow Dash like's to pull prank's a lot but I don't think she would go that far. Have you got the head with you? I want to see it for myself." asked Twilight.
"No, we don't have it, we left it at the campsite. Apple Bloom, will you go and get that head back from the forest campsite, please." asked Apple Jack.
"Ok." Apple Bloom said.
Apple Bloom ran through the town and into the forest to go and retrieve the head. She came back about half an hour later.
"Here, I have the head." said Apple Bloom.
"Thank you Apple Bloom. Come in you four, come and sit down." said Twilight.
Twilight went into the other room to investigate the head. She decided to cut through the head with the knife to see if it was made out of plaster or some material. But one thing came out of that head that she did not expect to come out... Blood.
"Um, Apple Jack, will you come in here please! NOW!" screamed Twilight.
Apple Jack ran into the other room as fast as she could.
"Apple Jack, please don't freak out. But I have something to say. I have investigated this head and... Um... Its Rainbow Dash's real head!" said Twilight with a tear to her eye.
Apple Jack started crying.
"No, it cant be!" screamed Apple jack.
"I'm sorry but it is." said Twilight.
"She was one of our best friends." said Apple Jack.
"I know she was Apple Jack, but now is the worst part, we have to tell those fillies in the other room. said Twilight.
"I know." cried Apple Jack.
"Girl's, can you come in here please!" asked Twilight.
The cutie mark crusaders came into the other room.
"Now, girl's, you know how we said that this head was a fake and that Rainbow Dash was pulling a prank on you... Well it's not a prank, this is Rainbow Dash's real head." said Twilight nervously.
"WHAT!" screamed the three fillies.
The cutie mark crusaders all started running around the house screaming and crying.
"Girl's please stop, I know its hard to stop because of this bad news but if you try to calm down, me and Twilight will find a solution to get to the bottom of this." asked Apple Jack as calmly as she could.
"Good, now that you have attempted to calm down, we will begin the investigation. Now, I have read a lot of mystery novel's, so I know how this work's, but what we defiantly need to do is find the rest of Rainbow Dash's body. When you found the head, was there anything with it?" asked Twilight.
"There was a note there!" said Sweetie Belle.
"Will you please go get that from the forest please, Sweetie Belle?" asked Apple Jack.
"Yes." said Sweetie Belle.
Sweetie Belle reached the forest, she entered it. she retrieved the note and began to run back but she was distracted by a blue ribbon.
"Oh, a blue ribbon, I think I will give it to Rarity, she loves this type of ribbon." said Sweetie Belle.
"Hello, Sweetie Belle." said a voice from behind a tree.
"Who's there?" asked Sweetie Belle.
"The insane mare!" said the voice from behind the tree.
Sweetie Belle looked at the note and realized that the note was signed by the insane mare. The insane mare came out from behind the tree.
"Derpy, you were the one who killed Rainbow Dash. Why?" asked Sweetie Belle.
"It will take to long to explain." said Derpy.
Derpy picked up the ribbon and tied it around Sweetie Belle's neck and strangled her to death with it... The Derpy eyed mare's second victim in this murderous rampage.
Just before Sweetie Belle choked to death, she looked Derpy right in the eye and said, "Buck you!" and then it was all over for her.
One hour later back at Twilight's tree house, the ponies started to think something was wrong.
"Why is she not here yet, something is wrong." said Apple Jack.
"I agree." said Twilight.
The four ponies left the tree house and went to the wood's. They walked along the path until they saw another body.
"Is that Sweetie Belle?" asked Scootaloo.
"She's been murdered!" screamed Apple Bloom.
"I'm sorry, but its to late now. But at least we have the note, we need to return Sweetie Belle's body to her sister, Rarity, and dealing with her about this is not going to be easy." said Twilight.
The four ponies carried Sweetie Belle's corpse to Rarity's house. they knocked on the door. Rarity answered the door.
"Hello Rarity. You might of heard the bad news of Rainbow Dash being murdered by some pony." said Twilight.
"Yes, I have Twilight, I have been crying all day about it, she was a good friend to all of us." cried Rarity.
"Well, I have more bad news, your sister, Sweetie Belle has also been killed." said Twilight sadly.
Twilight showed Rarity the body of her dead sister.
"NO! NOT HER!" cried Rarity.
She started crying her eye's out.
"I'm sorry Rarity, it's to late, but we are starting an investigation to find the cultrate of these death's. We already have some clue's. Do you want to join us" asked Twilight.
"Find her? I will DISTROY HER!" shouted Rarity at the top of her lung's.
"Ok, We will put the body in my tree house, it's the safest place to keep them, is that ok with you, Rarity?" asked Twilight.
"Yes, that's fine." said Rarity.
Meanwhile back at the forest, Derpy walks back home to make plan's for ore gruesome death's...
