A perfectly normal-looking apple.
Twilight in a salute position.
"This spell's a toughie!"
"But I feel lucky this time."
What a long neck you have there, Twilight.
Twilight pushing Pinkie away.
Pinkie you know better than to invade other's personal space.
Just wanted to say how much I love you.
Hee hee, excuse me, Twilight.
Orange bird, now I've seen it all.
This is gonna be so much fun!
"What a cute orange birdy"
and stunned Pinkie Pie, nice.
Um, Rairty, is it just me, or are you somepony in a Rarity mask?
Rarity's latest creation, lovely as it is!
I worked hard on this fabulous dress.
"Perhaps not my finest..."
You said what now Rarity?
Rarity, seems worried over Pinkie.
I'm looking up at you, Twilight.
Looks like she's in a rush.
I think I'm freaking out again.
An awkward moment between friends.
"We weren't going to turn her into an orange!"
Dashie ain't having none of these today.
Rainbow Dash smacking the fog with her tail
Oooh! Tasty cloud thingie!
What fun is this cloud thingie.
There is debate whether this Pink streak has a speed potential up to par with Rainbow Dash.
We don't usually see Rainbow Dash spinning around like that!
Dashie looking at a cloud.
Applejack happily pulling Apple Bloom in a wagon of apples.
Fluttershy having a tea party with Angel.
Pinkie Pie making a big grin
Good, just what I wanted to hear.
A butterfly on Pinkie's nose.
Fluttershy's face being squished
Fluttershy's face still being squished
Um...Pinkie...I don't think spines are supposed to bend like that...should I call a doctor now?
Fluttershy offering to help Pinkie.
That looks uncomfortable, Pinkie.
Rainbow flies in front of Pinkie.
Pinkie Pie's starting to feel the pressure.
Oh no! Pinkie looks frantic.
Twilight's spell turns a frog partially into an orange.
Twilight wondering about her friend's mental health
I've only got this much time left.
Ooh Pinkie, don't be silly.
Twilight inadvertently dooms Equestria with an offhanded remark
Clock is ticking, Pinkie. CLOCK. IS. TICKING!
What is she going on about this time?!
Wow Twilight, you have really big eyes.
Spike looks proud of himself.
That wasn't the answer Spike was looking for.
The Everfree Forest gets scarier every time.
Are those branches hands?
She's looking strangely happy
Who placed that dangerous hole in the middle of the forest?
Anyone up for Pinkie face pancakes?
Pinkie won't lie to herself.
"And into her own reflection she stared."
"Uh, yearning for one whose reflection she shared."
"And solemnly sweared not to be scared."
"At the prospect of being doubly mared!"
Just like in G1, except the copy's an adult too
"Okay wait- I promised not talk to myself anymore."
I'm finding it hard to distinguish one from the other
Pinkie Pie galloping off into the sunset with her double
Pinkie and her duplicate leaving the Everfree Forest.
Now Pinkie can find out how annoying she really is
Pinkie and Pinkie Pie duplicate leaving the forest.
Duplicate Pinkie Pie seems very excited.
I think I see a lollipop in the bushes!
Dashie at the water hole.
Rainbow is reading the same book again, although Twilight has a huge selection of Daring Do books.
That's enough reading for today.
Here I come Rainbow Dash!
"Come on in Rainbow Dash, the water is extra warm today."
"What exactly does she mean by that?"
Rainbow Dash, trying to figure out what Pinkie is going on about.
"I'm so glad you wandered by."
One of Fluttershy's critter friends bringing over a cheese for Pinkie.
Did I say "Applejohn?" I meant "Applejack!"
"Walls? But we're outside."
"Goodness. Was it something I said?"
Rainbow Dash is not amused
Gearing up to catch some zzzs
Am I crazy, or did I just see two Pinkie Pies.
For the sake of my SAN points, I shall remain too cool to care.
My Pinkie Sense is tingling...
This ain't gonna go well.
"Fun, fun, fun, fun, fun"
Okay...lead on Pinkie's...I promise there is fun.
How the heck is she able to whistle!?
And none but a leaf remained.
Rainbow Dash acting cool. Completely oblivious to the Pinkie Pie clone
Pinkie bringing Rainbow Dash a "floaty thing".
This can only end in tears...
The Pinkies invade the barn raising!
Quick, escape the crime scene before it's too late!
Alright! What is going on here?!
Where do ya think you're going?
Did Dr. Hooves visit the pool, too? There's two of him in the crowd!
An angry crowd at Twilight's doorstep.
No, I'm Batman!...Wait, wrong catchphrase.
Wait, how did they fit in?
Spike looks like a hypnotized doll.
Harry the Bear: "Oh Bother."
Awwww! So many cute Pinkie's!
Yee haw! Run along, little doggie!
Pinkies being taken to Town Hall
Twilight welcoming the Pinkie Pies.
"Just the opposite actually."
Dash with the real Pinkie
Just toss her down. She's only a worthless clone, after all.
"Pinkies. You've been brought here to take a test."
"Don't worry, It's a simple test; about as simple as they come."
The horror! The boring horror!
Aww, Why couldn't be watching grass grow?
Extreme concentration activate!
"Okay, maybe not that exciting."
Pinkie clone debating whether she wants to explode, or keep watching the wall. How hard can it be?
"Oh hey, Look at the birdy!" (Wrong choice Pinkie clone)
INFLATABLE PINKIE BALLOON!
That... did not look like fun.
"Watch me bounce and touch the ceiling!"
Hey, the hybrid frog is back!
"Look what I can do with my hooves!"
Lyra would be so jealous.
I can't believe the Pinkie Pie clone is surprised that the fourth wall is broken!
"Betcha can't make a face crazier than..."
The way they get sent back is terrifying.
"Can't take it anymore..."
"Somepony's making balloon animals!"
"Pinkie, you can look away now."
"You passed. You're the only Pinkie who kept staring at the wall!"
"I couldn't leave my friends... I just couldn't!"
Doing a quick check to see if it's the real me.
