This place was enchanting! It was almost as though we had stepped into another dimension. There was water everywhere, and it even poured down the walls. The sounds it created as it touched the water below soothed me. Even though the entrance was quite large, I couldn't feel the cold air from outside. It was as though these two places were separated by an invisible wall!

Dad grabbed my sides, and lifted me off his shoulders.

"There you go, Verdana." he said.

I grinned up at him, and raced over to a small pile of rocks. I took off my coat, my snowpants, and my boots, and I walked hastily toward the water.

It looked warm, but you could never be sure! I dipped my big toe slowly under the surface, causing the calm water to ripple slightly, and confirmed my previous thought - the water was perfect!

I was about to jump in, before two slender, but powerful, hands shoved me without warning, and sent me tumbling into the water with a loud splash.

Since I obviously wasn't prepared to be underwater, water rushed into my nose and mouth, and my body instinctively pushed itself to the surface in haste.

I emerged from the depths and began coughing and wheezing uncontrollably, rubbing my eyes. Sans, the one who obviously pushed me in, was doubled over, laughing hysterically.

When my lungs were able to function normally again, I shouted at the top of them.

"Sans! Why would you do that?! I can't believe you!" I scolded, my speech causing another coughing fit.

"What?" he managed to say through his chuckles, "You were practically asking for it!"

"Asking? What possibly could have made you thing that I wanted to be pushed into the wa-"

I was interrupted by multiple waves of water splashing me in the face. I swiped my hands over my eyes to clear my vision, before whipping my head in the direction of the splash-happy culprit.

"Papy?! I thought you were nice!" I gasped, swimming toward him.

"Nyeh heh heh! You thought incorrectly, dear sister. For I, The Totally Cool Papyrus, am always malicious in a splash battle!" he said, evily, before sending another splash attack my way.

Luckily, I was prepared this time, and blocked it with my arms.

"Nice try, Papyrus! But, you obviously don't know what I am capable of. I have been specially trained by the invisible water ninjas!" I gloated.

"Oh yeah? Show me what you've got!" he said, proudly, crossing his arms over his chest.

I prepared my attack, taking in a deep breath, and plunging underwater. I stayed there for a few seconds before bursting through the surface with my arms spread wide. I slapped my hands down in the water, causing an eruption of water to spray Papy, but I used my arms again, to push water upwards from below, and launch toward Sans, who was still not in the water.

They both whined in response. Especially Sans, who obviously didn't expect to be pelted with water.

Sans laughed it off, and bowed down to me, before jumping in to join us.

We continued our splash battle for a while, before stopping to play a few rounds of Marco Polo. Either Sans was really good at that game, or he was really good at cheating.

We played a few other games and swam around for almost an hour, before we retreated from the water and grabbed some towels.

After around 20 minutes of bad puns, we were dried off, so Mom and Dad let us explore Waterfall.

"Wowie! This place looks smaller on the outside... It's huge! Papy said, watching an pretty, blue flower.

He went up and touched it, and suddenly, we heard a faint voice.

"Wowie! This place looks smaller on the outside... It's huge!"

Huh? It repeated him! Although, it isn't the first talking flower I've seen...

"Verdi? Do you know what that is?" Sans asked, looking toward me.

I shook my head 'no.'

"Thought so. That's an Echo Flower. Dad told us about these, before. If you say something near it, it will hear everything and repeat it." he explained.

We were about to walk away, when we heard another voice.

"Thought so. That's an Echo Flower. Dad told us about these, before. If you say something near it, it will hear everything, and repeat it."

Huh. That's so cool.

We continued down the path for a little while, but Papyrus and I gazed at the gleaming rocks that were planted firmly into the walls and ceiling. They were absolutely captivating!

With our minds distracted, we had no idea where we were going. Suddenly, we were haulted by Sansy's arms. Why did he stop us?

Then we saw it.

A figure, hidden among the shadows, glared at us with an eye that seemed to be glowing

"Who dares to cross paths with me?!" the figure spoke.

My knees began to shake. This was scary! I tugged on Sans' sleeve, trying to get his attention.

"Uh... Who are you?" Sans asked, reaching for my hand.

The cavern was silent for a moment. Then, without warning, the mysterious being leapt from the shadows and aimed a wooden sword at us.

It was a girl? She didn't look much older than us. She had a leather eyepatch, and a few pointy, yellow teeth that stuck out in the front. She looked kind of like a fishy.

"Stay back! I'm on a mission!" she shouted, positioning the sword in front of Sansy's face.

She paused for a moment, drawing her sword back slightly.

"Say, are any of you humans?!" she accused.

"No, ma'am. We are skeletons!" Papy replied, gesturing to us.

The fish girl shifted her eyes over to me, meeting my gaze again. She looked confused.

"What about her? She doesn't look like you..." she poked her sword gently on Pap's chest.

"She's one, for sure! She's my sister. Why do you wanna know?" he said.

"I'm on a hunt for humans! After my daily training, I overheard the king say something about humans, and I immediately made it my mission to find one and bring it to him!" she explained, puffing out her chest.

"Humans? Can we help you look for some?" I suggested.

She thought for a moment, before nodding furiously.

"I guess you can be my partners! You guys look strong. I'm Undyne, by the way."

She stuck out her hand and we all shook it.

"I'm Sans. He's Papyrus, and that's Verdana." Sans introduced us.

"Cool names! Come on, let's go." She said, tugging us along.

Boy, she was strong!

We continued down the way, on an journey to find humans! I don't know what they look like, but I'm willing to help!

A/N

Hey, hey, hey!

I got some great questions to answer for the Q&A from last chapter! So, let's get right into it!

Q: What are your fandoms?

Oh boy, this is gonna be a long list... I don't know if I'm necessarily "in these fandoms," but I'm just gonna put things I'm into, to make it easier on myself.

Undertale, Until Dawn, Five Nights At Freddy's (kinda thought I was losing interest in it until sISTER LOCATION) TMNT, Deadpool, Yandere Simulator.

Wait... Do YouTubers count? Yeah. They do, right?

JackSepticEye, Markiplier, Pewdiepie, Jacksfilms, Onision/UhOhBro, Brandon Rodgers, Kubz Scouts, makemebad35, Kuledud3, Good Mythical Morning, Smosh (more specifically SmoshGames or Game Bang) JonTron, PeanutButterGamer, Jaboody Dubs, NateWantsToBattle, And Game Grumps.

Shoot. What about bands/song artists? Yes? I obviously do not fully understand the concept of fandoms.

Twenty One Pilots, Melanie Martinez, Panic! At The Disco, Fall Out Boy, Falling in Reverse, Marina and The Diamonds, and Halsey.

Phew, that was a lot of work.

Q: What are your Undertale ships?

Sans/Frisk, Frisk/Papyrus, Asgore/Toriel, Asriel/Frisk, Undyne/Alphys (duh...), Chara/Asriel, and I can't really think of any others!

Q: Who is your favorite Undertale Character.

Error 404: Author's ability to decide not found.

HOW COULD I POSSIBLE CHOOSE BETWEEN THESE LOVELY BEINGS?!

(it's sans lol)

Q: Are you excited for Civil War?

Yeah! But, I'm not as hyped as I was for Deadpool, haha!

Q: Do you read "ask character" books?

Yes, I do. I think they are super fun to read!

Q: Have you ever dyed your hair? If so, what color?

I have dyed the tips of my hair blue, but that's all. I've kind of wanted to dye my hair an auburn red or purple for a while, but I'm not totally sure I want to yet! I like my natural hair color... (which is blonde, if you were wondering)

Q: Do you role play?

I have a few times, but I haven't done it in years! Being an actor, I love to become a character.

Q: How did you come up with the idea of this story?

Uh... Im not really sure! I just saw sooooo many Sans x Readers and Papyrus x Readers, that I started thinking of other relationships people could share with them, and that's how the sibling thing got started!

Q: Do you like anime? If so, which ones?

I guess I do, yeah. I don't watch it too often, but I have watched a few shows: My Little Monster, Fairy Tale, The Devil Is A Part Timer, and one I forget the name of! It's about this student council, and there are other anime refrences in it! Have any of you seen it? I also watched Corpse Party, and I LOVED that one.

Q: What is your OTP?

I don't think I have one... :p

Q: Will you go to the bone zone?
