The Colorful and Dull strings

Reverse

Another peaceful day for Core, Ink and Error. When all of sudden Hacker frisk have come to visit them.

And just like before, Hacker frisk messed with the Three guardian of the Alternative Universe.

By Hacking there program and turn them into a kid like what happened to Error and Ink. 

But this time it Core and Error sans who were turned into a kid.

Ink just thought that Core frisk were adorable that he immediately engulfed her into a hugged.

Error who saw this were jealous that he used his strings to wrapped Core frisk and snatch her away Ink.

Even though Error turn into a kid. He was still the well known destroyer, Error just destroy the mood.

Error unconsciously hugged Core frisk and say to stay away from them.

Core frisk were surprised for the first time when Error sans wrapped his arms to her in a protective way.

Ink just grit his teeth as he pout at Error sans. Core frisk just sighed as she gently remove his arms around her.

Even Core Frisk were turn into an adorable little kid. She just told them to kneel down beside each other.

"Didn't I told you both no fighting" Core said while crossing her arms.

Ink and Error just kneel down and point at each other.

"It's Error/Ink's fault"

"No pointing at each other, we have to  work together to find Hacker Frisk to revert us back to normal"

"Aww, but, but, Corey you look adorable like that"

"No" Core frisk said with a firm tone.

"Hehehe" Error just snicker at the dejected expression Ink have.

"Error, don't also pick a fight on Ink, I told you both no fighting nor arguing, Were friends here"

The Two Sans just nod there head obediently as they shake hands as a proof they made up.

Little she doesn't know, They were actually glaring at each other when Core frisk turn her back and thought of a way back to normal.

"I can't believe even you become a small kid, You still have that nasty attitude of yours"

"Well much better than a guy who pretend to be nice and innocent"

Ink and Error is merely clashing with each other. When Core Frisk gotten an idea she faced them and they were back into a good sans.

Ink and Error just give her the sweetest smile they could make. As she spoke about the plan to revert them back to normal.

"So your telling me, I have to searched Virus Sans to find Hacker Frisk since that's what happened to you"

Core Frisk just nod her head. Ink wasn't against of a favor from Core frisk but he didn't like the idea that core Frisk and Error Sans spend more time together.

Ink is definitely against so Ink just called his friend, Fresh sans from his Universe.

Error smug grin were replaced by grimace expression as he didn't like Fresh sans that much. Error just absolutely against of staying at Fresh sans universe.

Core frisk also didn't want to encounter Fresh Sans. "No let's just go back to Undertale instead"

"Eh? But Fresh is very good at handling kids"

"That's right, Undertale will do?" Error abruptly replied as he sweat profusely.

Since it was Core frisk, Ink couldn't disagree about it. That's why he just teleport them to Undertale and leave them be. Before Ink leave he just firmly asked Sans a favor

"Definitely take care of Core Frisk alone, and not together with Error"

"..." Sans were merely speechless.
