(Y/n) and Frisk saw a big laboratory standing in front of them. "Whoa." (Y/n) said. Frisk opened the door and she followed her into the building. They looked around as they walked through the hallway. Soon a yellow monster with glasses walked out from one of the doors and turned around. She looked almost like a Simpsons character. Her eyes widened as she saw the two girls behind her. They smiled and waved. She starts to panic. "Oh, my god! I didn't expect you to show up so soon! I haven't showered, I'm barely dressed! It's all messy! And..." "whoa, calm down!" (Y/n) said. She quickly turned to face them. "Um... h- h- hiya. I'm Dr. Alphys. I'm Asgore's royal scientist! B- but, I'm not one of the "bad guys" actually, since you all stepped out of the ruins, I've been, observing your journey through my console." She said. "Oh! So you're the one who set up those cameras." (Y/n) said. She nodded nervously.
"Um, yes. I've seen your fights, your friendships, everything! I was originally going to stop you guys, but... watching people on a screen really makes you root for them." She said. "S- so, uh... now I want to help you! Using my knowledge, I can easily guide you through Hotland! I know a way right to Asgore's Castle, no problem!" She said. Frisk and her sister lit up. "Really? You can do that?" Frisk asked. "That's awesome, Alphys!" (Y/n) said. She blushed a small bit out of shyness and continued. "Well, actually, um, there's just a tiny issue." She said. (Y/n) and Frisk looked concerned.
"What's wrong?" (Y/n) asked. "A long time ago, I made a robot named Mettaton. Originally, I built him to be an entertainment robot, uh, you know, like a robotic tv star? Anyway, recently, I decided to make him more useful, you know, just some small practical adjustments." She trailed off. She sweat dropped nervously. "Like uh,.. anti... anti human combat features?" She asked. "Oh great." (Y/n) said. "O- of course, when I saw you two coming, I immediately decided I have to remove those features." She said. "Did you?" Frisk asked. "Well, uh..." she said. "I'm going to take that as a no." (Y/n) said. "Well, unfortunately, I may have made a teensy mistake while doing so. And um, now he's an unstoppable killing machine with a thirst for human blood?" She said.
She then chuckled nervously. "But um, hopefully, we won't have to run into him." She said. "I am most definite that we're going to run into him." (Y/n) said. Suddenly they felt shaking in the building. "And here he comes." (Y/n) said. They began bouncing off the floor from the shaking. "Oh no." She said. Suddenly they heard a robotic voice. "OH YEAH! Welcome beauties!" They turned to see a square looking robot with two arms, his right hand holding a microphone. "TO TODAY'S QUIZ SHOW!" He announced. He tried his best to sound energetic, but couldn't due to his robotic voice.
Suddenly disco balls hung from the celling and confetti was thrown everywhere. "Oh boy! I can already tell it's gonna be a great show! Everyone give a big hand for our wonderful contestants!" Mettaton said. Another spotlight showed on the girls and the robot clapped for a moment. "Never played before? No problem, it's simple. There's only one rule. Answer correctly. Or you die!" He approached the two. "Let's start with an easy one! What's the prize for answering correctly?" Suddenly different answers appeared below. A: money, B: mercy, C: new car, and D: more questions. "Uh... um..." (Y/n) said as she tried to figure it out. What they didn't notice was Alphys making a D shape with her hands, giving them the answer from behind the robot. "Is it mercy? Ow!"
(Y/n) yelped as she got zapped. "Hey!" Frisk glared at the robot. "Sis, wait!" Frisk pointed toward Alphys. "Oh... is it... D?" (Y/n) asked. "Right! Sounds like you get it!" Mettaton said. "Here's your terrific prize! What's the king's full name?" They saw more answers below. A was Lord Fluffybuns, B was Fuzzy Pushover, C was Asgore Dreemurr, and D was Dr. Friendship. "Asgore Dreemurr!" Frisk said. "Correct! What a traffic answer! Enough about you, let's talk about me! What are robots made of?" They looked at the next choices for answers. A: hopes and dreams,
B: metal and magic, C: Snips and Snails and D: sugar and spice. "You forgot the and everything nice part for the D." (Y/n) got zapped again. "Ow! What the hell! I didn't even get the answer wrong!" She snapped as she glared at the robot. "That was a lame joke, so I shocked you anyways." Mettaton said. Frisk snickered. "You know, if you're just going to shock me for random reasons I'm not going to play your stupid games." Mettaton then constantly began to zap her. "Ow! Ow! Ow! Okay! Okay! Fine! Just quit it!" (Y/n) shouted. Mettaton stopped zapping and (Y/n) huffed and crosses her arms. "It's metal and magic." Frisk answered. "Too easy for you, huh? Here's another easy one for you." Mettaton moved aside and they gasped at how long and far the next question was. It was impossible to read it.
