(Inspired by the two photos on top. You can probably guess what it's gonna be about.)

Ink's POV (You didn't expect that huh?):

I was at Sci's lab waiting for him to finish talking with his worlds Alphys. Since he was one of the smartest Sanses I'm sure he could make something that would help defeat Nightmare's gang.

Sci finally came through the door next to me.
''Sorry to keep you waiting Ink. What do you need?'' he asked.
''I need something to make the Bad Guys weak so we can put a stop to what they're doing to the multivese.'' I explained rather quickly.

''Well... I have something but... it's still work in progress.'' he said deep in thought.
''It doesn't really matter. What is it?'' I ask hopefully.
''It's a laser gun. I tested it on some animals, it made them peaceful and cooperative. I didn't test it on monsters yet.'' Sci explained briefly.

''I could always test it on them!''
''Hmmm... wait a second and I'll bring it over.''

Nightmare's POV:

Almost my whole team went on a 'vacation' to their boyfriends or whatever. I didn't care honestly since it would mean that I would also get a break from them. The only one that stayed was my glitchy boyfriend Error, who was sleeping in my lap as I petted his head.

We sat there comfortably, the only sound being Error quiet purring. But of course, this moment had to be ruined.
''Prepare to be defeated!'' Ink yelled suddenly appearing beside us.

Error woke up with a yelp and then fell to the floor.
''Bitch.'' I started while looking at Ink. ''Not only are you bothering me during vacation, you also have the guts to scare MY boyfriend?'' I said while glaring at him.

He shook in fear as he pulled something from behind his back. Before I could register what it was I was blinded with an bright orange light.

I slowly blinked, as I regained my vision I realized that everything looked... bigger? Wtf did he do to me? I looked down at myself only to see that I was covered in thick black fur, my hands were replaced by paws and... is that a tail? Did he turn me into a fucking cat?!?

''Well... that was unexpected.'' I heard Ink say. Wait... did Error get hit too? I anxiously looked over the edge of the couch to see that.... yup! he's a cat now. He also had a black thick fur and fluffy tail, his eyes were a bit different. The eye whites were actually white, one eye was just a normal yellow cat eye while the other had two coloured iris, the inner ring was blue while the other was yellow.

''Shit... I gotta call Sci.'' Ink said again.
''Oh! Now you want to call him?'' I said sarcastically. He just looked at me strangely before snickering.
''Pfffha, holy shit that sounded adorable.'' he said thought laughter.

I looked at him strangely, questioning his sanity.
''You just meowed.'' he explained still snickering. Great, just fucking great. I hoped off the couch and went to check in on Error.

''You okay glitchy?'' I asked while nudging him with my head.
''How does it fucking look like? I'm God damn cat!'' he said irritated.
''You look cute thought.~'' I said with a wink.
''Shut up, now's not the best time to flirt.'' he said, blushing slightly.

''Awww!~ You two are so cute!'' I heard Ink shout out, before he moved his hand to try and pet one of us. That, was a big mistake. I hissed loudly, my fur puffing up and then I scratched his hand with my claws. Error on the other hand was in the kitchen on top of a fridge in less than a second, weather he teleported there or just ran there, I didn't know.

''Mother fucker!'' Ink yelled yanking his hand away. I just walked away, to the kitchen.
''Can you come down?!'' I yelled to Error.
''Can but don't want to!'' he yelled back.
''Alright, wait a second.'' I said before hopping onto the counter.

Few more jumps and I was on top of the fridge next to Error. I quickly go to him, kinda curling up around him. He purrs at this and we just cuddle there for some time, until Ink shows up again. This time with Sci luckily.

''I knew I shouldn't have agreed to this...'' I heard Sci mumble.
''You're lucky that the laser is in test phase so this-'' he gestured towards us ''will only last few hours.''
''Oh thank God.'' I said, going back to cuddling Error.

Ink and Sci left soon after so we moved back to the couch. Cuddling each other while we both purred loudly. You know what? This isn't actually half bad.

(Hope you all enjoyed. Bye~)
