US! Chara (Nara): ...

Chara: Nice me...he..hehe... ! KILL IT WITH FIRE! BURN THIS UNHOLY CREATURE!

Asriel: Chara no! Be nice!

Chara: No! There's already another me doing so! *grumbles* chocolate bar now...

Nara: Sans, Papyrus...what's going on? Oh no it's Frisk!

Bb: Hey Chara, well...oh Nara! And calm down. This Frisk is nice just like you, weird isn't it?

Nara: Very. Where-!

Frisk: No escaping rooms with a buncha monsters. Text boxes can talk to you and so can a random voice.

Sans: Your gettin' numb to this huh?

Frisk: Pretty much. Hey the text asked you and Fell a question.

Sans: Oh? Let's see...oh him...he just gives off bad vibes. Plus those pictures didn't help his case. I don't if that's me or somethin' he's just creepy...

Fell: Og's right. That motherfucker ain't nothin' but trouble. Those pictures...Bb looked so scared...hey fuck you I can cuss when nether the hell I want! You ain't gonna do jack!

Bb: Fell calm down! Oh the text box request me? A friendly fight with the Papyrus me? Sure! Papyrus! Papyrus!

Papyrus: Oh hello Bb! You called?

Bb: The text box request us to have a fierce but playful battle! I don't really wanna fight though...

Papyrus: Me neither...I've got it! How about a pillow fight? That way it can still be fierce but playful! Also soft!

Bb: That's a great idea! Let's do it!*runs to a room and grabs pillow*

Papyrus: *does the same*

Bb: Ahhhhhhhhh! *charges*

Papyrus: Nyehhhhhhhhhh! *hits Bb softly*

Bb: Oh no! The great and powerful blueberry has fallen! But not before I take you too!*hits Papyrus back*

Papyrus: NNNOOOOOO! *fakes death*

Sans: Oohhhhhkkkkkk. *hears whisper* hehe what do ya mean? *eye flickers slighty*

Frisk: You ok Sans?

Sans: Yeah..don't worry about Frisk. Answer your question.

Frisk: Well ok...um besides Error everyone here is ok in my book.

Error: Why does no one like mE? I haven't DOne anythIng yet.

Frisk: Yeah...yet.

Error: I thought you were the nice one...Frisky.

Frisk: D-don't call me that. Only Sans gets to. *blushes slighty*

Error: Well I am one of the many so, pick and choose Frisky~.

Frisk: *horribly fluttered* Geez...ok I'll give you a chance. Mess up and we're not cool got it?

Error: Of course Frisky... *leaves*

Sans: *watched with a scowl* Flirting with my Frisk now huh? I'm on to ya Error. Oh thanks, I guess. I needed these.

Alphys and Dyne: *Fan girl scream* YYYEEEEESSSSSSSS!

Fell: Ow my freakin' ears ladies!

Asgore: Oh look! The text box gave us some tea. Please Tori-I mean Toriel would you like some.

Toriel: ...fine...Asgore. *blushes slighty* You may call me Tori again. Don't mess that up.

Asgore: Thank you! I-i won't swear!

Papyrus: I simply adore them! Please could you make some for Bb? He hates puns just as much as I do and since there's multiple Sans now, there's bound to be some terrible puns.

Chara: Thanks...dork.
