Alfys decided to mix the liquid with ketchup so Sans wouldn't take notice to the taste, if it even has a taste. After Alfys was done, she woke up Sans. "Psst! S-Sans wake up." Alfys shook his arm gently. "Huh?" Sans woke up and staired at Alfys curious to why she woke him up. "H-Here, I have ketchup for y-you." Alfys handed Sans the ketchup, Sans took the ketchup and thanked Alfys.Once Sans finished his ketchup, he almost immediately fell back to sleep. "J-Jeez, he sleeps t-to much" Alfys mumbled before going to experiment on her latest project.
(Sans's Pov)
I woke up feeling a bit, weird? I felt a bit different, there was black stuff hanging over my face. "What..?" I muttered. I hopped off the table I was sleeping on and looked around, I saw a mirror on the other side of the room. 'It's so far..' I thought. I eventually made it to the other side of the room, thanks to my drowsiness I tripped a couple of times..
I looked in the mirror to see a, human? "What?" I asked to no one in particular. I touched my cheek, but the human did the same thing. Then I realized that the human was me. My eyes widened in shock as I looked at my reflection. I had blue eyes, pale skin, and hair..I had longish black hair. "Funny, you would think it would be white or something.." I mumbled tugging on my hair. "Ouch!" I winced.
(Back to no one's Pov)
"ALFYS!" Sans screamed from the other room. Alfys rushed into the room almost tripping on the way. "W-What, Sa-" Alfys stopped when she saw a human standing in front of her. "S-Sans!?" Alfys screamed. "Ow! Alfys you're too loud!" Sans yelled covering his ears.
"S-Sorry!" Alfys apologized. "What happened to me? I feel strange.." Sans frowned. "T-This is so cool! I-I have to tell Undine!" Alfys ran out of the room leaving Sans confused and annoyed.

After what felt like hours, Undine and Papyras walked into Alfys's lab. They stopped dead in there tracks when they saw a human playfully blowing there black bangs out of their face. "UH..HUMAN?" Papyras asked. This startled Sans, he fell off of the table and landed on the ground with a thud.
"Ow.." Sans mumbled, sitting up Sans looked at Papyras and Undine's confused faces. "Heh, heh..." Sans chuckled nervously. "I think Alfys did something to me." Sans sighed. Papyras walked up to Sans and picked him up. He held him out to get a better look at him. "Bro, can you put me down?" Sans asked.
"OF COURSE BROTHER." Papyras said. Papyras gently set Sans down. "So punk, you think Alfys might have something to do with this?" Undine asked. "Well, ya know any other scientist able to do this? Besides I was asleep most of the time. She probably put something in the ketchup she gave me." Sans shrugged his shoulders and sighed.
Alfys walked into the room and nervously waved. "S-Sorry about Sans, I-I got a little distracted. But don't worry! I-I'll go find a cure to Sans nightmare problem!" Alfys squeaked running off to who knows where.
"Papyras, I think we should keep an eye on Sans.." Undine sighed. "AGREED..NYEHEH."
