Yes this was inspired by this Video here.
Twilight Sparkle and Dusk Shine looked around at the Saddle Arabian city that had replaced Ponyville in this timeline and were trying to puzzle out how that worked when the heard horns being blown. The next thing they knew there was a parade going past as the singing started.
Make way for Princess Fluttershy
Say hey! It's Princess Fluttershy
Then the very familiar voice of Discord began singing as a very embarrassed alicorn Fluttershy rode past on a Ursa Minor that looked like a very smug Angel Bunny.
Hey! Clear the way in the old Bazaar
Hey you!
Let us through!
It's a bright new star!
Oh Come!
Be the first on your block to meet her eye!
Then Pinkie joined in sing as she bounced around in front of the Ursa Bunny.
Make way!
Here she comes!
Ring bells! Bang the drums!
Are you gonna love this gal!
Princess Fluttershy! Fabulous she!
Fluttershy of Cloudsdale
Genuflect, show some respect
Down on one knee!
Now, try your best to stay calm
Brush up your sunday salaam
The come and meet her spectacular coterie
As they watched they saw Discord teleporting and shape shifting into different ponies amongst the ponies watching as he sang.
Princess Fluttershy!
Mighty is she!
Fluttershy of Cloudsdale
Strong as ten earth ponies, definitely!
She faced the galloping hordes
A hundred diamond dogs with swords
Who sent those goons to their lords?
Why, Princess Fluttershy
Next thing they knew Pinkie was balancing on a ball on the back of a camel by her nose while singing.
She's got seventy-five golden camels
Purple peacocks
She's got fifty-three
When it comes to exotic-type mammals
Has she got a zoo?
I'm telling you, it's a world-class menagerie
Then Discord appeared in front of them in a gold tuxedo as he sang.
Princess Fluttershy! Beautiful is she, Fluttershy of Cloudsdale
That physique! How can I speak
Weak at the knee
Well, get on out in that square
Adjust your tux and tail and prepare
To gawk and grovel and stare at Princess Flu...
"STOP!!!" Mayor Made yelled into a megaphone. "Discord! I gave you permission to put on a production of Aladdin in a theater. NOT! I REPEAT NOT! TRANSFORM THE ENTIRE TOWN INTO A GIANT STAGE AND SING COPYRIGHTED SONGS IN A WAY THAT WILL GET US SUED! CHANGE EVERYTHING BACK AND I MEAN NOW!!!!!!!!!!" With that she turned and started stomping back towards her office, but then stopped in front of the cutie mark map and looked at Twilight Sparkle and Dusk Shine. "Do I even want to know?"
"Just passing through from different alternate timelines." Dusk Shine said as the time portal opened and sucked him and Barb up into it.
"Well please come again when things are less crazy." Mayor Mare called out as Twilight and Spike got sucked up into the time portal just as Ponyville returned to normal.
