I've written what Anon might be doing during each episode. But what was he doing during the movie? Here's the trailer for now, till I get an opportunity to re-watch the movie.
 
THIS SUMMER!
"Who the fuck left all this snow in my yard? Lazy ass fucking bird ponies. Winter wrap up my ass."
ONE MAN!
"Mommy, what's that green, spindly thing?"
"That's the human, don't look at it sweetie."
ONE DECISION!
"ANON! Get back here! Pants are not optional for you!"
"I don't see you wearing pants Twilight."
"That's because my genitals don't look like something you'd find stuck in a shark's teeth!"
ONE VOICE OVER!
"Damn it Discord, stop narrating my life!"
CRITICS ARE CALLING IT SENSATIONAL!
"I believe this sensation is called disgust."
IN A TIME OF CRISIS!
"You want me to do what?"
"Find and stop the Changeling Queen, Chrysalis."
"I must have corn in my ears or something, say that one more time Sunbutt."
FOUR FRIENDS!
"With Discord, this changeling-"
"My name is Pharynx, you jerk."
"And some random guard."
MUST UNITE!
"I think you must be drunk Celly, do we look like the Elements of Harmony?"
EQUESTRIA AS WE KNOW IT WILL NEVER BE THE SAME!
"You know the guard will probably die before we reach the train station."
THIS WILL BE ONE EPIC ADVENTURE!
"This is going to be the dumbest adventure ever."
"I know. Isn't it wonderful?"
"Blow it out your ass Discord."
 
 
And now our feature presentation.
----------------------------------------------A month before the events of the MLP Movie-------------------------------------------
 
The sun is peaking around the edges of your curtains, disturbing you from a good nights sleep. For once, you've woken up feeling refreshed and alert.
Flinging open the curtains and the window you inhale deeply. Another glorious day in Ponyville, ahhh, smell that fresh summer air.
The smell of fruit from the farms, the smell of fresh baking from Sugarcube Corner. That dusty, hay smell that reminds you that you live in a town full of small horses.
Still, you're in an unshakably good mood this morning. You almost feel like singing. In fact you do feel like singing!
"Better check the calendar."
Let's see here, according to this you haven't sang a song for three months. So you should be okay to follow through.
Can't be too careful, too much singing and your faggotry levels might reach critical. You'd have to forfeit your man card if that happened.
But not today!
Swiftly donning your clothes before the mood fades, you throw open the front door, stepping outside with a flourish.
You're already heading into town with a jaunty stride as that magical musical accompaniment, no doubt sensing your imminent faggotry, begins to pick up.
 
"Morning in Ponyville shimmers! Morning in Ponyville shines!"
"And I know for absolute certain! That everything is certainly fine!"
Some ponies join in, marching beside you as you Julie Andrews your way past the shops on the main street.
"There's the Mayor en route to her office!"
"Seriously why Sofas AND Quills!"
One of your backing dancers mutters "I've been wondering that too." Good to know someone's got your back.
 
"Morning in Ponyville shimmers! Morning in Ponyville shines!"
Your backing dancers pipe up again. "Isn't this Princess Twilight's song?"
"And I know for absolute certain! That this song is definitely mine!"
She didn't finish the song, can't claim something you didn't finish. That's the Law of the Sea. Salvage Rights and Shanties.
"There's two dykes on the way to the market!"
"Hi Anon."
"Hi Lyra."
"We are not dykes! Darn it Anon."
"Come on Bonnie, we kinda are."
"There's the Flower Sisters fainting again."
Got mad improv skills today son.
 
"My Ponyville is so gentle and still. Can things ever go wrong? I don't think that they will."
"Actually things go wrong quite a lot."
"That's enough out of you snarky, backing dancer pony. You're interrupting my song."
"Sorry."
 
"Morning in Ponyville shimmers! Morning in Ponyville shines!"
"And I know for absolute certain! That everything is certainly-Ooof"
 
A sharp bolt of pain shoots up your spine, instantly killing your stride, song and that magical instrument free music.
You recognise this pain quite well. It means close contact has occurred between a pony's face and your testicles.
A recurring problem during your first months in Ponyville before everyone got used to the height and line of sight differences.
Which means whoever just reached second base with you is not local.
Gritting your teeth, you look down to see a perturbed Guard.
"My apologies sir. Message for you from Princess Celestia for you sir." The guard holds out a scroll to you. "She requests your presence urgently sir."
He's saying sir a lot. Probably a coping mechanism, trying to deal with the fact he just got teabagged in the middle of the street.
Before you can open the scroll the guard interrupts "Uh... sir? If I might make a request?" He seems a little flustered.
Holy shit you've managed to fluster a guardpony. You now hold the secret to breaking the implacably stoic Royal Guard. Your power is LIMITLESS!
Control yourself Anon, don't let him know you know their weakness. Your testicles. "Yes?"
"I have another message for the Spirit of Chaos, Discord."
"And?"
"I-I was wondering if maybe you could deliver it for me." The guard clears his throat trying to regain his former stoic guarditude. "He just freaks me out, sir."
Interrupts your song, headbutts you in the nuts then asks for a favour.
You sigh audibly. "I suppose I can." Your morning routine usually takes you past Fluttershy's cottage anyway.
Because you're a nosy jackass and also because Discord would probably feel insulted, in his own weird way, if you brought him unopened mail.
You're gonna open his mail. Let's see what we got here. Oh. It's exactly the same letter you got. Urgent summons.
Better not be about the comedy club you and Discord Chapelle did at the Gala.
Celestia may have found it funny but as far as the rest of the crowd were concerned, you were dying on your feet.
Best get this sorted quickly. To Fluttershy's! He practically lives there these days.
How those two haven't taken each other dancing, vigorously and horizontally, yet is beyond you.
Beyond most people in fact.
-----------------A short walk later-----------------
"Discord you in there?"
A flash of light, a brief sensation of nausea and a sudden eye watering change of surroundings.
"Yes and so are you!"
You fucking hate teleporting.
"No time for the usual fun and games Discord. We got business to take care of."
Discord reacts to your stern tone by slithering through the air and behind your back, looming over your shoulder like an evil conscience.
"Ooooh? Do tell."
Stepping away from the looming shoulder devil, you toss the scroll at him.
"Celestia wants us."
"Well who wouldn't want the pleasure of my company?"
"I can think of quite a few but we don't have time for mucking about."
Discord floats over, pinching your cheek like a disapproving grandmother.
"And here I thought you knew how to have fun." Another flash of light and a diary appears in his claws. "When does her royal sunniness expect us."
Snatching the diary, you toss it away. "Today. Now. The next few hours." Gotta be firm.
He rolls his eyes. Before you can protest you're teleported again. When your vision clear you find yourself in- Oh for fucks sake.
You appear to be in some sort of tacky 1920s club. Or maybe 1940s. Or maybe you're just in Las Pegasus.
Whatever, it looks like the kinda of place you'd find pinstripe suits and gangsters who say 'See' at the end of every sentence.
"Discord!"
"What?" He has an injured tone in his voice, like he's done nothing wrong.
"We don't have time for this."
"Well someone is a grumpy one today, what put you in such a bad mood."
"I only sing four songs a year, I'd quite like to get back to finishing the one that royal mail just interrupted."
He lets out a dramatic sigh. "Fiiiine."
Another flash. AGAIN WITH THE FUCKING TELEPORTING!
Two in a row, you feel a little like vomiting. You're still suppressing the feeling when you hear the melodious, motherly tones of Celestia.
"Anon, Discord. Thank you for coming so quickly."
"You're welcome, Princess."
"Yeah, what he said." First he doesn't want to come, now he's all you're welcome and stuff.
"I will be brief with both of you, since time is of the essence."
That post teleport nausea just got wiped out by a wave of foreboding.
"Anon, you and Discord must find and capture the changeling queen, Chrysalis."
Wow. That is.... Wow. Quite the bombshell. Wait a minute, there's a fucking chaos spirit with unlimited magic right here.
"Ok then Celly. Discord. You heard the lady, one changeling queen in a cage please."
Discord raises a claw but Celestia quickly interrupts.
"I'm afraid it won't be that simple. We've had word that Chrysalis is in possession of a fragment of her magic dampening throne."
Oh, Twilight told you about that thing. Nasty business.
"It's not a large piece but it is enough to shield her from magical attempts to locate her."
This is starting to sound a bit above your paygrade, hunting changeling queens with Discord. You have been on an adventure or two but this...
"Don't worry Anon, it won't be just you and Discord. Pharynx of the Changelings and one of my Guardsponies will be joining you." Celestia apparently saw something of your internal doubt in your face. "They're already waiting for you in the lobby."
Discord says something and leaves, you didn't catch what it was but he seemed eager to start, your own thoughts are in turmoil.
"Celly-"
"I know what you're thinking Anon but you're the best beings to send. Discord has great power. Pharynx has knowledge. And you... have a unique way of thinking."
She's giving you that motherly 'I believe in you smile'.
"And the guard?"
"I thought it might make things go much more smoothly. My little ponies might get the wrong idea if Discord, a changeling and a well known eccentric troublemaker were wandering Equestria together."
You're being sent on a dangerous quest and Sunbutt can still crack a joke.
"Why not Twilight and the others, surely they'd be a better choice."
"Perhaps. But Luna and I think it will take a different kind of friendship to stop Chrysalis."
"But none of us are friends." Not even you and Discord, you're more partners in pranks than friends. "Most of us haven't even met."
Celestia lays a reassuring hoof on your shoulder. "That's why you're going Anon. I believe you have the power to bring them together."
"You've met me before right."
"Don't be afraid Anon, there's more to you than the eccentric stranger you portray yourself as." There's that smile again. Guess you're not weaseling out of this quest.
"I best get going then."
"Good luck Anon."
First task. Gather your party before venturing forth.
 
As you enter the lobby to gather yon party and venture forth, things seem off to a good start.
The changeling and the guard are death glaring each other, sort of. Things in a Equestria are a bit too cute to death glare properly.
It's more 'he took the last muffin' glare.
And Discord is helping things along by poking them both with a stick. Yep. This is your team.
Okay. You can do this. Princesses believe in you. First things first. Don't scream internally.
...
Check. Step two. Remember that hope and good always triumphs in the end. The changeling won't betray you all.
The guard pony is not two days from retirement. Discord can be serious when the situation calls for it.
And you are the nobody from a small town who becomes the chosen one and saves the day.
Now what would the protagonist do right now? Restore order.
"Enough fooling around you lot, we've got a job to do."
All three pointedly ignore you. Hmmm, right. Seems you need to establish yourself as the leader. The Twilight Sparkle of this little friendship adventure as it were.
What would she do? Learn a... no. That won't work, you're not really in the sort of situation to solve this issue while learning about friendship.
Wait, Pinkie taught you a trick that just might work.
"Everybody pay attention." No one does. So you reach behind your back, thinking silly thoughts just like Pinkie taught you to do.
Silly thoughts. Silly thoughts. Silly thoughts. Your arm suddenly feels like it's holding a heavy weight, you whip it back round into view pulling an object from hammerspace. Or Pinkiespace.
"I SAID PAY ATTENTION!" Now confronted with a human scale party cannon, your erstwhile companions look at you.
"Now I don't like to use the pay attention cannon but we don't have time for mucking about."
"What do-" *BOOM*
---------------------------------------The Train to the Crystal Empire-----------------------------------------------------
You're feeling rather pleased with yourself. Already you can feel your party bonding over shared experience.
Okay, so the guard is giving you dirty looks while picking confetti out of his mane. And the changeling is looking at you like you're crazier than Discord.
But you can accept that. It might not be Princess of Friendship grade bonding. But you can accept a role as the Drill Sargent who brings everyone together in mutual hate.
At least Discord isn't being moody like the other two. He's just floating up and down the carriage annoying the other passengers.
Whatever, gives you time to focus on staving off the imminent onset of a great deal of stress and pressure.
Gotta block out the fact that you're on a mission to stop a legit super-villain.
