Is my singing terrible? Yes.
Is my impersonation of the ponies bad? Yes.
Do I really care? No, it was fun as hay to make this.

Parody of the song of My Littlest Pet Shop - You can watch it here http://www.youtube.com/watch?v=-nZowPYMfQQ
(I also couldn't find a way to remove the lyrics so I just lowered the volume of it in the back)

It's a cute little show. If you liked MLP, check it out.

So with that, I just knew that a crossover needed to be done and came up with this. Shame I'm not a girl who can sing to make it properly.

Lyrics:

I'm gonna tell you 'bout a few friends
So just watch me
Don't steal the show
Sit on back and try to follow

My name is Twilight (Sparkle)
and to make it short
I'm the big star here
There's nothing that I don't report

Rarity: Uh hi, ah, I'm Rarity, actually I'm a bit of a star too, yeah, actually, a bit more in the fashion sense

Rarity is my good friend
Ask her any thing about vogue
'Cause that's what she's a passion for

And when she's thrilled
Yeah, you can tell
She'll make a scene about it
And you'll hear one of her yells

RD: What's up with that?
AJ: Yeah, that's kind of...

Rarity: What?

Yeah, that's Rainbow Dash in the air
She likes to show off but admit it
She is really kind of awesome

She's also loyal
And she has some guts
Not very bright, but she's one of us

We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) Pony ponies
We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) My Little Pony ponies

Pinkie Pie is a very friendly pony
Always looking for a way
to put a smile on your face

She's gonna party here
She's gonna party there
Okay, she's disappeared
Does anyone here know where she's at?

PP: Ohhhhh, you're new here, do you know what this calls for? Do you? Do you?

FS: Eat your carrot Ang- *coughs* Oh dear *coughs* Not again...

This is Fluttershy, she's so kind
She loves all the creatures
but her posture is a bit loose

Sure, she has some fears
That gets the best of her
But we don't mind at all
Because she's one of us

We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) Pony ponies
We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) My Little Pony ponies

RD:Aww, Derpy!
Derpy: Oops, sorry Rainbow Dash.
AJ: Um, Twilight, maybe you need to hurry up, we seem to be making quite a mess here

This is Applejack
A really tough one
Her hard work and honesty
have no known boundary

Derpy
Are you okay? 
And that's everybody 
So what do you say?

We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) Pony ponies
We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) Pony ponies
We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) Pony ponies
We're the My Little (My Little) Pony ponies
Yeah, the My Little (My Little) My Little Pony ponies
