Yup, a special flashback for me to this image… Let’s say, breaking the upload and my comment post timelines, this takes place for at least a month after the other image…

Twilight Sparkle : GAAAHHH!!! breathing, then went silence, she sighed What a crazy night…
Pinkie Pie : wakes up Mmmm, good morning, everypony. yawn Well, another new day, another-…

Starlight Glimmer : Twilight! There you are. Me and Spike have been waiting for you to come back home from the party last night, but you didn’t-…

Starlight Glimmer : O-Oh, wow, didn’t expecting that. Can you tell me what the hell is going-…

Starlight Glimmer : Well, I guess we’ve got ourselves a problem here…

Starlight Glimmer : …once I’ve arrived there, I talk to Mrs. Cake, who is sweeping the floor, telling about Twilight’s whereabouts. She told me that Twilight was sleeping in Pinkie’s bedroom upstairs, so I’d go there, only to find what will be something that freaks me the freak out; Twilight and Pinkie were both in the same bed together with their manes messed up. They both screams at me in their embarrassment, which makes me I have to shove myself out of that room. Mr. and Mrs. Cake notices the scream too. After that, we have a nice chit-chat together about the last night’s incident; yet again, Twilight’s spiked a punch once again in that place, just like what she also did about a month ago. I know there’s a reason why she wants to stay there, it’s because she really want to have some “fun” with Pinkie Pie in the bed again.

Spike : laughs Oh, really?! That’s absolutely embarrassing! Yeah, it takes me back from a month ago when she and Pinkie did the same thing. At least if you remember back then, when we head upstairs to Twilight and Pinkie, they both on their bed, which is wet and untidy, and the room smells bad back when we enter it.

Starlight Glimmer : Of course! I also notice that too when investigating that same room for today, same bad smell and same smelly bed. Guess this is yet another time you’ve done something like this with Pinkie, right, Twilight?

Twilight Sparkle : covers her face to hide her embarrassment Ughhhh…

TS: Celestia! Last night must’ve been.. ? must’ve…. Sweet Celestia.  
TS: Wow. The party last night was so wild I can’t even find my cutie mark! How embarrassing:
 
“Knock Knock. Oh good morning Mrs. Cake. Is Pinkie around? I think I left my cutie mark here last night.”
 
TS: Hahhaahaa. That’d be so embarrassaiiiinn..
 
TS: Oh Celestia Damn It! STARKLIGHT! STARLIGHT! WHERE HAVE YOU GONE OFF TO WITH MY FRIGGIN’ CUTIE MARK THIS TIME!!!

Party hard then sleep soundly =D

@Shepherd  
“NOONE IS SAFE EVERYONE WAKES UP HUNG OVER NEXT TO PINKIE PIE EVERYONE!!!”  
“I even woke up hung over next myself.”  
“Pinkie that doesn’t make any…mirror pool?”  
“Sure if that the answer that’ll help you sleep at night.”

Yep this happened,
 
To all of the main six
 
Including Pinkie Pie.

“I’m never getting drunk on New Years Eve again…”

Twilight really needs to stop getting so wasted.

hmm I didn’t know Twilight and Pinkie ship name was “twinkie”, Now I’m imaging Pinkie sleepy asking “Where’s the cream filling?”

Oh dear

Much pie was eaten that night
