As Frisk noticed some of the townspeople looking at them closely, they moved back through Snowdin in the direction of Waterfall. Sans was nowhere in sight, and honestly? They weren't too upset about that. He was much scarier than he had first seemed.
I should get rid of him, so that he doesn't pose a threat to me in the future… Frisk thought. After a second they realised what they had thought and felt with horrified. What? No! I don't want to hurt him! I don't want to hurt anyone!
Frisk was snapped out of their thoughts when they heard Papyrus calling to them from where he was standing outside his house. "HUMAN? WHAT ARE YOU DOING HERE?! YOU'RE SUPPOSED TO BE WAITING FOR UNDYNE!"
"Oh, hey Papyrus… uh, yeah I'm going back there now, I was just… hanging with Sans at Grillby's for a bit." Frisk replied nervously, still thinking back on their strange thoughts. They were also thinking back on Sans's threat.
…Did Sans threaten me? I don't think he did, actually… Frisk thought, before adding, it was implied, though.
"UGH, OF COURSE SANS WOULD TAKE YOU TO GRILLBY'S… DIDN'T I WARN YOU ABOUT THAT PLACE?" Papyrus looked like he was about to start a rant about why Grillby's was bad again.
"Yeah. Yeah, you did. Don't worry; I don't think I'll be going back there." Papyrus seemed pleased. "Anyway, I should be getting back to waiting for this 'Undyne'."
"ALRIGHT! DON'T FORGET TO CALL!" Papyrus yelled as Frisk headed back towards Waterfall. After assuring him they wouldn't forget, they moved out of his sight before trying to access that super speed they seemed to possess.
After accidentally running into a couple trees, they finally got the hang of it – albeit not without having to push down their hunger on multiple occasions after hurting themselves.
Once Frisk got the hang of their newfound speed powers, they sped off to the waiting point. When they got there, it seemed as if nothing had changed. The flower man, the monster kid, even Sans was sitting in his original spot – although he seemed to be watching them a lot more.
They nervously headed over to his sentry station. When they were standing quite close, all he said was "we should hang out again sometime." Then he fell silent again. Frisk shifted uncomfortably.
Fortunately, they didn't need to be uncomfortable for long, as soon after they heard someone yelling from further in Waterfall. "HEY! HEY SANS! ARE YOU HERE?!" The yelling was getting slightly louder, signifying that whoever it was doing the yelling (and Frisk had a pretty good idea of who it was) was getting closer.
Suddenly, a huge figure came through the hallway that leads further into Waterfall. The figure was completely clad in metal armour, with a big red thing that could've been a feather but could also easily be hair coming out of the helmet. "PAPYRUS CALLED ME JUST A WHILE AGO AND SAID THAT-"
The figure froze in what seemed to be shock, although it was hard to tell when their face was covered by a helmet. They seemed equally torn between looking at Frisk and also looking at Sans. "…He said that a human came through here." The figure finished. "Wow, Sans. I didn't expect you to be awake. Also. Is that a human? I can't tell."
Before Frisk or Sans could answer, the armless monster child interrupted them by running in between the figure and themselves and Sans. The monster kid tripped and fell over but pulled itself back up, already exclaiming "YO! UNDYNE! I've been waiting for, like, forever to talk to you! You're the coolest! Did you say something about a human?! Can I help you escort them?"
The figure, who Frisk now knew to be Undyne, seemed pleased at the praise. Undyne took the helmet off, which revealed a female humanoid fish face, which had a huge toothy grin on it. The red stuff was hair, pulled into a ponytail. "HELL YEAH I'M THE COOLEST! …Uhh, I mean… HECK YEAH!" Undyne's grin looked slightly more sheepish now.
She moved her focus back onto Frisk and Sans. "And about the human… SANS! Explain!"
Before Sans could say anything, Frisk (who was getting slightly annoyed about being referred to as "the human" and not actually being talked to) said "Would it kill you to be at least slightly polite? No one has even asked my name yet, and you're all talking as if I'm not standing right here."
Undyne, Sans and the monster kid stared intensely at Frisk for an awkward amount of time. It seemed to be something that was happening a lot more than they would like.
Eventually, MK (monster kid) broke the silence by shouting "Yo! You're human?!"
"Something like that, yes." Frisk replied, while staring back at Undyne and Sans with equal intensity.
Suddenly, Undyne laughed and slapped them on the back, which caused them to grit their teeth as to not brutally murder her. "I LIKE you, punk! You're sassy! This will be loads of fun!" Undyne said excitedly. She didn't seem to notice that Frisk was tensed up and changing back and forth from slightly human to mostly monster. Neither did MK, as they were too busy looking at Undyne.
Sans noticed, of course, but he didn't do anything. Just watch them. Study them. He still hadn't said anything to contribute to the conversation yet.
While a part of Frisk was grateful Sans hadn't spilled the beans on them not being very human at all, another part of them wanted him to tell everyone he could because that way people would be able to know what precautions to take if they were around.
No, wait. It's good that Sans is the only one who seems to know more than that something's off! If I kill him, NO ONE WILL KNOW! Frisk thought, before once again feeling horrified at themselves. It's just the hunger talking, it's just the hunger talking…
They repeated this to themselves over and over, trying to block out the invasive thoughts, but one in particular broke through. I wonder if I can live off of monster dust instead of blood…
They were suddenly snapped out of their thoughts when they were shaken very violently. "HEY! SNAP OUT OF IT!" Undyne shouted in their face. They realised that they had started turning into their beast form and had been repeating "It's just the hunger talking" over and over.
They felt a sudden fear that Undyne would figure out what they were, and before they could stop themselves they rewound time back to just after Undyne had hit them on the back, but this time they stopped shifting their forms almost immediately.
They immediately chastised themselves for doing it after they caught Sans's shocked expression, before his face turned back to normal. He'd probably never let them out of his sight again. On the upside (if it could be called that), Undyne clearly didn't remember what had happened, which proved that so far only Sans and Frisk could.
"ALL RIGHT NERDS! Let's get going!" Undyne said before heading towards the hall from which she came. MK and I walked beside her, and waited by the edge of the room as she turned to say one last thing to Sans. "Also, good job Sans. I never thought I'd see the day where you weren't slacking off."
Sans slouched down again and addressed Undyne, though his eyes were still on Frisk. "well, it's a big moment, ya know? the last human. things'll be getting interesting from here on out, i think."
Undyne nodded in agreement and turned back to the exit, leading Frisk and MK out without another word. They felt Sans's eyes on their back as they left, but they were more occupied with thinking about what Sans had said. Something about the last human. Which implied that there were more around. Come to think of it, Papyrus had sort of mentioned other humans as well.
That isn't good. I came here so I didn't have to feed off of anyone. But I guess the whole plan has backfired completely, Frisk thought, Although… it couldn't hurt to have a couple drinks from these humans… after all, I'm sure they'd be willing to let me feed on them if I tell them what happens when I don't feed…
Frisk was once again snapped out of their thoughts as Undyne said something. "God, I was supposed to build a puzzle for this room... But I HATE puzzles. So I just put a huge pile of rocks upstream." They turned their head to look at Undyne judgementally. Papyrus must be rubbing off on them. "What? Don't judge me! My lack of creativity's making your life easier!"
After Frisk was done judging Undyne, they actually took a look round the room. There was a huge waterfall flowing down from the ceiling, with rocks falling down with the water. There was also another magic box. There was also a sort of calm patch in the middle of the waterfall that made a safe path through – except for the boulders, of course.
"Well? What're you waiting for?! Let's get across the deadly puzzle!" Undyne shouted.
"Sure thing, Undyne!" MK replied enthusiastically. Undyne walked along the path with MK following close behind her. Whenever any of the rocks seemed like they would hit her, she just put her arm out and stopped them. She must be quite strong.
When the two of them reached the other side, Undyne turned and called back to Frisk. "All right NERD! Try and beat THAT!"
Frisk raised their eyebrows and a smirk pulled at their lips. They swiftly zoomed from one end of the path to the other, and any rocks that were in their way shattered. They enjoyed the baffled shock on Undyne's face and the amazed look on MK's.
"DUDE! How'd you do that? C'mon, you gotta tell me!" MK shouted excitedly.
"Maybe another time." Frisk replied, suddenly aware of how Undyne was watching them warily.
Thinking back, that probably wasn't the best idea… It seems not everyone is as stupid as Papyrus. The "hunger thoughts" were starting be quite mean. Papyrus isn't stupid. He's just innocent and naive. Frisk corrected.
As Frisk came back to reality, they realised Undyne was saying something. "…You're like one of those AWESOME super humans that're in Alpyhs's human history books!" She didn't seem to be wary of Frisk anymore.
Hmph. Maybe they are all quite dumb. Frisk ignored the thought. They instead replied to Undyne.
"Uhhh, yeah. Super humans are pretty rare though. So I'm not surprised you haven't seen any until now." Frisk lied. While they had been talking they had also been walking, and now they were in a shadowy corridor with some tall grass growing in the middle of it. There was a path higher up but there didn't seem to be any way to get there from where they were.
While they were moving through the grass, Undyne looked curiously at Frisk. "How much do you know about the humans down here?"
"Not much, only that there are humans here. Which came as a nasty surprise." Frisk replied.
"Oh, do you not like humans? That's okay. Some of the other humans didn't like humans, but they warmed up pretty fast! Well, except one of them, but they haven't warmed up to anyone, really. Other than Asriel. I don't like that one much. But they're good for sparring with!" Frisk listened intently to Undyne, wanting to learn more about the other humans down in the Underground.
"Yeah, Chara is always mean to everyone when the King and Queen aren't around." MK added to the conversation.
"You'd have probably seen at least one of the humans by now, if they weren't at a celebration. They're celebrating the anniversary of the day Chara fell here." Undyne told Frisk as they were leaving the dark hallway.
The three of them entered a room with a small pond that had a waterfall flowing down from it in the middle of the path. There were a bunch of plants to the side, and a sign on the wall. The sign read: "When four bridge seeds align in the water, they will sprout."
"ALL RIGHT NERDS!" Undyne yelled, startling Frisk. "WE NEED TO GET ACROSS THIS POND! GET TO IT!" She instructed, before jumping across to the other side. Frisk could probably do that as well, but they wanted to do the puzzle. Also MK probably wouldn't be able to make it.
They floated the seeds across the water in a line of four, which then sprouted into a bridge. MK and Frisk both walked across. Undyne looked baffled. "Wait, did you actually DO the puzzle?! You can't just jump across?! You can't do the jimpity jumpity joodle?! The limpity loppity leap?!"
Frisk just snickered and neglected to answer Undyne, as well as ignoring the voice in their head that was commenting on how Undyne seemed like she was insane. They all moved forwards into the next room. Standing around the room were a few types of monsters, only one of which Frisk recognised (which was a Moldsmal). One of the other monsters seemed to be a turtle with a tank on its back. The tank was half filled with water and there was a bird sitting in it. The other monster seemed to be some kind of merman, except with a sort of horse-like face and lots of abs. Most of the monsters left as they saw the trio, but not the Moldsmals. They just wobbled around.
The room itself was basically a bigger version of the previous room, with a river and a pond and a waterfall in it. The puzzle was also just a more complicated version of the previous one.
"Alphys helped measure out the mud tiles for this puzzle. It was a lot of work, but we got to make sand castles after. We're a good team. She's great at building them... And I'm great at wrecking them! There's barely even a trace of 'em now." Undyne commented. "Anyway! You do your thing!" She shouted, before jumping across the river.
Although the puzzle was a lot harder than the previous one, Frisk still managed to complete it. They all moved through a framed doorway into a room with sparkling stones all over the ceiling, and a bunch of echo flowers around it. There was also a telescope, and a sign that said "WISHING ROOM".
"Every day, people come here and wish to the stars... I won't let them down! I'll make everyone's wishes come true!" Undyne shouted enthusiastically.
"My wish has already come true, Undyne!" MK told her. "I wished that I'd be able to help you escort a human, and now I am!"
"AWESOME!" Undyne yelled. "Hey, do you have a wish?" She asked Frisk. They nodded slowly. "Add it to the pile, punk."
"…I wish I wasn't a vampire…" Frisk whispered, looking up at the star stones.
Why would you wish that? Being a vampire is great! You're super strong, super fast, hard to kill… And now that we know there are humans down here, we could live forever! The voice in their head informed them. They ignored it, turning back to Undyne and asking which way it was next.
"This way!" Undyne said, leading them past the telescope and up a corridor that seemed to be a dead end. "Now! I know what you're thinking! 'Undyne, this is a dead end!' BUT GUESS WHAT, NERDS?" She punched the wall and it caved in on itself, revealing another path. "IT'S A SUPER COOL SECRET PATH!"
It isn't too secret if you show us… They were now on a boardwalk amidst dark water. The water had a bunch of water sausages growing out of it. There were also many plaques on the walls that, when inspected, revealed sobering information about the war between humans and monsters, as well as facts about souls. There was also an unsettling picture of an indescribable beast.
At the end of the boardwalk there was a platform the size of one person. Undyne informed Frisk that if they stood on the platform, it'd take them across to another part of the walkway. Undyne also asked them to go ahead, as the platform would come back.
They stepped on the platform and were carried across the murky black water. It was quite concerning to be standing in the middle of the dark water, and they turned back to look at Undyne. They saw her putting her helmet back on with a gleam in her eyes, before they hit the other side of the boardwalk.
As the platform was heading back towards her, she shouted "ALL RIGHT, HUMAN! HERE'S THE DEAL! YOU HAVE TO RUN TO THE END OF THE LONG HALLWAY WITH ME CHASING YOU! GET GOING!"
Frisk quickly swirled around and started running, not bothering to look at their surroundings. As soon as they started, they heard whooshing sounds come from behind them. Before they could turn around and check what the noise was, spears flew past them on both sides. Not ordinary spears, of course. Glowing magic spears. They heard Undyne laughing manically behind them and the stomp of her boots as she ran to catch up with them.
Frisk picked up the pace.
Meanwhile, someone else was wondering why things kept repeating.
