Underfell Sans and Underfell Papyrus were walking through the cruel depths of the Underground. Suddenly they both felt a strange shiver. It wasn't a cold shiver, it was like a earthquake shiver. Something felt wrong.
"Boss, did ya feel that?" Underfell Sans said, looking at his taller brother.
"Of course I did you idiot!...What do you think it was?" His brother said, feeling uncertain.
"I dunno, ya think the other Sanses and Papyruses felt it?"
(B/N)'s POV
It was Saturday morning, my lazy sibling must be sleeping! I was so mad at (Y/N) that I didn't even want to make pancakes!
"Get up you lazy bones!" I screamed at the top of my lungs to them. All I heard was a lazy groan. I sigh as I give up and made my stupid sibling some breakfast.
I swear if I wasn't so great, I wouldn't even wake them up! That's when I heard a knock on the door. Who could it be? I was excited that it might be a new friend to make! Some people compare me to a dog, since I'm so cute, cuddly and excited all the time. It was kinda weird since I didn't like dogs, but whatever.
It was Undyne! How exciting!
"Undyne!" I yell in excitement.
"Papyrus!" They yell back.
"What are you doing here?" I hum, beautifully.
"I'm here to see Alphys but their 'busy'" Undyne said, sighing in frustration. Alphys and Undyne were dating ever since we left the Underground, it must be all of my hard work into Alphy's esteem! I'm such a good friend.
"Well, why don't we help Alphys!" I hum, always happy to help my friends. Undyne nodded in return. It was settled then! As I happily finish cooking San's food I leave a note for them.
"(Y/N), off to help Alphys in their lab! Here's some food, lazy bones!" I write and walk off with Undyne.
A while later, we go towards Alphy's new lab. It was smaller than their old one in the Underground but still functional. As we enter, Alphys seemed nervous and shaky.
"Alphys!" I said, waving towards them. They look back at me with a surprised face.
"P-Papyrus, Undyne?!" They said, looking at both of us.
"What are you two doing here?" They gulp.
"We're here to help you with whatever you're doing!" Undyne said with a brave, sharp smile. Alphys looks at us and stays quiet for a moment.
"Oh, that's really generous of you...but I wouldn't want to waste your ti-"
"Nonsense!" I say, cutting them off.
"You're not wasting our time! Our time is not wasteful!" I smile as they look at me with a sigh.
"Fine..." They say, probably knowing that Undyne and I don't take 'no' for a answer.
A few hours later,
Alphys was finished with her work, they still looked nervous though as if their problems weren't fixed. I just waved it off as Alphys kinda always looked nervous. I guess they were just a paranoid person! As the three of us watched something called "anime" together, I suddenly felt the need to go towards the bathroom.
"Excuse me guys! I need to use the restroom!" I say, walking off.
As I walk towards the bathroom, I look over the multiple lab rooms Alphys had, one in particular catches my eye. While the door was closed, I could see something glowing due to the crack under the door. What was it? I looked around, I really shouldn't peak...but...I'm just so curious! If I don't, I won't be able to sleep! I slowly open the door to see...a portal?
Woah. I walk into the room, the portal was really beautiful. Why was it here? Was this that made Alphys so nervous? I walk towards it, I couldn't stop myself...I just needed a closer look. This portal attracted me, I slowly put my hand in...then my entire body. I'm sure Alphys won't mind if I go inside.
