Shadow and Thorn are busy setting cupcakes on a fire and throwing them at Somebody. None of them reach their target. 

Cyclone is  eating pie. 

l duck as a flaming carrot flies overhead. It hits Thorn, who roars and spews fire at Volcano, the one who threw it. Shadow, rather annoyed, blows black fire at MP. Chaos ensues. Well, that is until l grap the mirophone and yell at everyone the this is a ball, and they ought to act civilised.

It works, more or less. 

*sashays into ballroom fashionably late, dragging Isaac from TFiOS by the hand*

Oh, don't mind me, darlinks. I just simply could NOT find anything to wear. Better late than never, eh?

*runs up onto stage and grabs microphone* 

*wearing the dress pictured below, along with a pair of white ankle boots and a few bracelets*

Long dresses were never really my thing. I tend to trip over my own feet a lot. Also I'd probably look like a bride or something if this were to be longer. *coughs* Anyways.

Please, no one fight over Isaac. I know, I know. He's gorgeous and amazing and perfect in every possible way, but I'M. His. Date. I'm watching you, ladies. *narrows eyes for a moment; then smiles wildly again* Have a fabulous evening, folks! I'll be performing my hit single, "Don't Even Look at Him, He's Mine," later on. I'll also be DJing the rest of the night, so if you have any requests, feel free to let me know and I'll be happy to - HEY! I SEE YOU OVER THERE! GET AWAY FROM ISAAC OR PREPARE TO FEEL MY WRATH. *flings self off of stage and attacks random girl*

*television colorbars* *BEEEEEP*

Somebody: Okay, so we're having an FFA now? 

Shifting: *snaps and summons computers*

Volcano: YES! STARCRAFT!

*play Starcraft II FFA*

GLaDOS: *crashes party with Chell* *claims vacant microphone* *sings Still Alive* THIS WAS A TRIUMPH. I'm making a note here, "Huge success." It's hard to overstate my satisfaction. Aperture Science-- we do what we must because we can. For the good of all of us-- except the ones who are dead. 

----THREE HOURS LATER----

Bill: Hey, are you doing anything after this?

GLaDOS: Are you flirting with me? 

Bill: Yes...

GLaDOS: *hits him across his triangular face with robotic hand* 

Volcano: *singed* THAT WAS FUN.

Devil: *also singed* Yup, IT WAS.

Volcano: I dare you to eat one of your vegetables.

Devil: NEVEEERRR!!!!!

Somebody: Okay girls, time to head back. 

Fruity: Vybb!

Sicily: fppe! 

Shifting: Looks like I have to go... but first... HEY BILL!

Bill: Yeah? 

Shifting: YOU OWE DIPPER HERE SOME YARN!

Bill: *sighs* FINE. *snaps fingers, and yarn appears* Tell Shooting Star to have fun with it.

GLaDOS: Who is this "Shooting Star?" Is she what some people call your "girlfriend"?

Bill: NO!

*rest of argument cannot be heard as Somebody and Co. travel home*  

BACK AT THE RANCH... ER, HQ...

Shifting: Uggg , I am never wearing a corset again.

Volcano: I set everything on fire!

Somebody: Yeah, I noticed.

Shifting: Dipper wasn't half bad. I mean, I still ship Dipcifica, but that's a yet-to-happen. 

Somebody and Volcano: *nod*

Somebody: Hey, where's Fruity?

Shifting: Conked out on the couch.

Somebody: *puts Fruity to bed* And we should be following suit. Last one in bed is a rotten egg! *runs upstairs*

Volcano: Hey! No fair! *follows Somebody* 

Shifting: I'm an immortal ghost with no need for sleep! *phases after them both*

BEHAVE YERSELVES AES!!!

OR THE BALL POLICE WILL GET YOU!!
