Our story starts on the highway of Ponyville with a car going fast, passing every single car in it's path.

Fluttershy: *driving car* What's his problem?
Pinkie Pie: I don't know.

Bob was the name of the pony that was driving fast, and he did not want to let anyone get in his way

Bob: *passes Sean*
Sean: *brakes*
Rainbow Dash: Jeez.

Bob: *passes another car*

(May I join? XD )

Mirage: *driving on the highway a little further ahead of Fluttershy's presence, when Bob passes him, almost ramming his car*

Yes, thank you for joining

Bob: *passes Spike's car then drives off highway, going airborne*

Mirage: Holy s***!

Spike: *stops car*
Sean: *stops
Fluttershy: *stops
Spike: *gets out* Did you see the way he went sailing out there?! He just went.. Sailing out there!

Mirage: *stops the car and runs downhill to the wreck* Oh man... there's nothing I can do here...

Sean: *looks inside* Hey! No one's in the car!
Pinkie Pie: *sees Bob* There he is!

Mirage: *trots over to Bob with all the others*

Spike: He's still alive.
Fluttershy: We gotta call an ambulance.

Mirage: Dang, my battery is dead!

Sean: Hey, I'm not a doctor or anything, but I have some medical experience. I'm a dentist. Do you think you're hurt?
Bob: Is he kidding?

Mirage: We could just take him to the nearest hospital ourselves...

Bob: No, forget it. They won't get here in time. Now listen, there's all this dough. 350 G's. Do you hear what I'm saying? 350 G's! It's all burried under the park, under this big W, in Santa Rosita. It's next to The Crystal Empire. You just gotta dig it up, under a big W. You'll see it. It's burried under this big W!

Mirage: What? Money? Uh... why?

Bob: It was mine, all mine. But they kept trying to take it from me! So I burried it, under this big W. Since I'm dying, I want you guys to have it, but watch out. Watch out for them cops. They'll most likely be everywhere. *dies*

Mirage: He's gone... *turns to the others* Do you think he was telling the truth?

Bob: *Wakes up* Aunt Belle?! *grabs Sean* I didn't mean to do it Aunt Belle!! Please, tell me no matter what, it don't make no difference! Say it!!
Fluttershy: For Heaven's sake tell him.
Sean: It don't make no difference.
Bob: Thanks, *kicks soup can, and dies*

The soupcan rolls to the bottom of the hill.

Mirage: Wow... that was weird... I hope he rests in peace now...

Pinkie Pie: Me too, cuz if he jumps up like that again, I'm getting outta here.
Spike: Shouldn't we burry him? *looks at Fluttershy*
Fluttershy: What are you looking at me for? All I got is this sweater

Another car pulls up, and two ponies wearing fedoras, and business suits come out of the car.

Mirage: Who are these guys?

Sean: I don't know. It could be the police.

One of them starts coming down the hill.

Spike: Are you sure it's the police? They don't normally drive Ford Mustangs you know.
Fluttershy: If it is the police what do we do?
Spike: Just answer their questions, but don't tell them anything about the money, otherwise we'll be stuck here all day.
Pinkie Pie: We can't be stuck here.
Fluttershy: Yeah, we're going to St. Petersburg in Florida.
Sean: Me, and my special somepony are going to have a date.
Spike: My special somepony is in my car with our mother in law.

Mirage: All right, just act cool, here they come...

Sean: Are you a police officer sir?
Police pony: *Checks body*

After checking the body, he looked at his friend on top of the hill

Police Pony: YUP!!
Cop: *calls ambulance*
Police Pony: How long ago did this happen?
Fluttershy: About five minutes ago.

Mirage: We saw this pony losing control over the car and driving off the road...

Police Pony: Did anyone actually see it happen?
Spike: He passed me, and that's when he went sailing out there.
Police Pony: Was he already dead before you got here?

Mirage: No. He must have crawled out of the wreck and died over there, before we reached him.

Police Pony: Did he say anything when you got here?
Pinkie Pie: *shakes head no*
Police Pony: I said did he say anything?!
Spike: What about?
Police Pony: WHAT DO YOU MEAN WHAT ABOUT?!!? Did he, or did he not say anything.
Sean: He said something, but it was uh-
Spike: Embarrasing
Police Pony: What was? Come on, come on!!

Mirage: He babbled something about his aunt or something... we're not sure.

Police Pony: What?
Pinkie Pie: *points to Sean* He thought this hedgehog was his Aunt Belle.
Police Pony: Alright, enough.
Cop: *comes down* What happened here?

Mirage: Um... we just old your partner... We don't know anything else.

Police Pony: They came down here to see if they could help. Well, I think that's about all we can get from this group. Get outta here.
Sean, Spike, Fluttershy, and Pinkie Pie: *go up hill*

Rainbow Dash: Sean, what happened?
Sean: Oh, just something bad.
Spike: *walks to car*
Twilight: Well?!
Spike: It was terrible, very terrible.
Rarity: Oh, the inside of my stomach.
Spike: Take it easy, these things happen.
Twilight: Man, what kind of an attitude is that? "These Things Happen." They only happen, because this country is full of careless ponies that see these things happen, and just say these things happen, and that's why they happen!
Spike: Let's try not to get upset.

Mirage: Indeed. We've done everything we could. Let's get out of here...

Spike: *drives*
Twilight: Now what did that pony say?! Tell every bit word for word, and don't leave anything out!
Rainbow Dash: Why are you looking at the road like that?
Sean: Be quiet, I'm watching something.

Pinkie Pie: *looks back at Mirage*
Fluttershy: Pinkie, don't look back. Play it smart. We gotta keep our cool.

Mirage: *glances at Pinkie from the corners of his eyes and raises a brow* (Why is she looking at me like that?! Feels embarrassing...)

Rarity: I don't really feel comfortable getting this money. We should've called the police.
Twilight: Man what do the police have to do with this?
Rarity: I think they were chasing the pony that just died.
Twilight: Of course they were, he was speeding!
Spike: Well what's important now is that we gotta find the money.
Rainbow Dash: Well do you think he meant it?
Sean: *smiles* Dash, I don't know about you, but some of them believed it like those two in the back
Rainbow Dash: *looks back*
Sean: DON'T LOOK!!

Fluttershy: I know where the money is, it's under a big W. That's what he said. It could be anything like a waterfall.
Pinkie Pie: Geez. I hope it's not under a waterfall. Then we'd get drenched.
Fluttershy: Please, think of something that starts with a W!

Mirage: *glances at the other car and sees the others are having a discussion* Probably talking about the money... and as like in the past, everyone wants to leave the earth pony out of the business! Oh, no, not this time! That guy said the dough is under a big W... Big W.... what the hay does that mean?

(Mirage is driving a '58 Plymouth Fury, btw, just like in your fanfic. :)

Twilight: The only reason Spike wants to get the money is because he is running a company that makes gems for ponies to eat!!
Spike: Yeah, but-
Twilight: And he used $40,000 of his own money, including $15,000 of my cash to run dat company!
Spike: Yeah, but-
Twilight: Yeah, but what?!
Spike: M-most people like it, and I like it!

Rainbow Dash: What if that pony was playing a trick on you? Did you think of that?
Sean: Really? What kind of a pony would play a trick on a bunch of strangers, with every bone in his body broken? Now, big W... What?

Mirage: So we are falling for this... All right, let's do it. If the money is there, we can share...

Pinkie Pie: Watch
Fluttershy: No
Pinkie Pie: WATCHTOWA!!! :D
Fluttershy: No.
Pinkie Pie: A wall!
Fluttershy: no!
Pinkie Pie: Walnut tree
Fluttershy: No!
Pinkie Pie: Walnuts!
Fluttershy: NO!!!!

Mirage: Wallaby? XD

Twilight: Man, why you only doin 35? Step on it, and see what happens!
Spike: They'll just follow us.
Twilight: It's worth a shot.
Rarity: Twilight, he's not that good of a driver.
Spike: *accelerates*
Sean: a, ha. *accelerates*
Fluttershy: A ha!! *accelerates*

Mirage: Fine. If you wanna be that way... *accelerates*

All four of us were going over 70 miles an hour for no reason.

Spike: *slows down to 20*
Twilight: Man, why you stoppin?
Spike: It's no use, they'll just do whatever we do.
Rarity: Oh, the inside of my stomach.

Mirage: *slows down a bit too* So how do you propose we settle this?
