A/N: *Blows party horn* Happy New Year, guys! So far, my 2017's been so-so: I didn't really do anything special for the new year, just hung around with my brother at home, though I DID go out to Mass earlier this evening. Oh yeah-and my Tumblr account was randomly terminated -_- I already sent a message to the website, so hopefully it should be restored by tomorrow. This is actually the third time this has happened though...that raises questions. But mostly, it's just a pain in the butt. On the plus side, I was finally able to watch Moana today. It is now one of my favorites. Now then, before I get to the next chapter, on to answering reviews:

XXPay4XtraShippingsXX-Yeah, poor Mabel. And Dipper, for that matter. Care to join the Skeletwin Protection Squad? Yeah, Toby is perfect for Burgerpants, IMHO XD Glad you like my future ideas...though I actually wanted you to tell me which you want to read more, so I know what to write next...

Random Guest-Good to have you on board :) Glad you're liking the story so far.

Pierce-Thanks, m8. I hope you had a great Christmas, and have a good new year! As for that one Undertale fanfic-I'll look for it sometime. Maybe...

Okay, so that's one vote for my FNAF story, and one for a sequel/side story to Under Gravity. Well, enough stalling. It's not very long, but I hope you enjoy the next chapter of Under Gravity!

Disclaimer: I don't own Gravity Falls or Undertale-they belong to Alex Fox and Toby Hirsch. Or something like that :P

Out of all of the things Pacifica Northwest had done in her life, never, EVER, did she think she'd be stealing from the trash. There she was, walking through the labs, and made the decision to enter an office. Once inside, she saw something glinting inside a trashcan. Taking a closer look, she saw that it was more gold.

"Who'd toss perfectly good gold away?!" Pacifica asked, her voice a bit too high. "That doesn't make sense!"

For a moment, she just stood there quietly, her hands in her pockets.

"Well…I guess I can't just leave it there…" She slowly started to reach to the garbage can-then shook her head.

"Ugh, WHAT am I thinking?! I'm about to steal from the trash! What am I, a peasant?! I have my pride!"

She started to walk off…then thought about the others. Maybe Robbie could use the gold to help with his rock star career? He was miserable as a scientist…and she had given him a hard time earlier. She owed him something for the help he'd given her…

"You owe me for this, metal butt." Pacifica sneered, making a face as she stuck her hand in the trash and fished the gold out. Thankfully, the gold was all that was in there. No old, rotted food, old coffee cups, or anything. All the same, Pacifica wished she had some hand sanitizer. After shoving the gold in her pockets, she walked back outside-and right into a fight.

"Freeze, human!" Standing there in front of the girl were…gnomes. Literal gnomes, like the kind people would put in their garden. Three of them.

"Look, I don't have time for this." Pacifica said. "I'm trying to get to the Capital, okay? I don't want to fight!"

"Well, maybe we could make an arrangement?" The gnome in the middle asked. He seemed to be the youngest, as his beard was brown instead of gray, like the others. "We'll let you go-if you marry us!"

"Marry you?!" Pacifica cringed. "Like-all THREE of you?!"

"Of course not!" The lead gnome answered. "All one thousand of us!"

"No way!" Pacifica answered. "That's not happening, you little trolls!"

Wrong choice of words…

"Fine then, if that's the way you want it!" He turned around. "Let's get her, boys!" As Pacifica watched, more gnomes appeared from the shadows, crawling towards Pacifica. Twenty…thirty…there were far too many to count…

The blonde's heart started beating faster.

"Stay back! I'm warning you…!"

But it was an idle threat-she knew it from the beginning. There were far too many of them-her stick wouldn't help her. She could only watch as they gathered together, all the gnomes forming a giant gnome that towered over her.

The giant gnome monster let out a terrifying roar, and Pacifica screamed. It tried to smash her with its fists, and Pacifica took off running down the corridor.

"I can't believe I'm running from a bunch of garden decorations!"

She was then sent flying from the force of the giant gnome's fists.

"Augh!" She landed hard, on her funny bone, and pain shot up her body. It didn't help that she was still pretty weak from her fight with Tambry. The next thing she knew was the wind being sucked out of her lungs as she was swiped up, lifted into the air.

She was weak, scared, and her vision was starting to fade.

No! NO! I can't die!

But the next thing Pacifica knew, she went falling through the air, not even able to scream.

"Gideon! Gideon, hang on! Stanley, do something!"

But nothing could be done. It was already too late for Gideon.

Just as he planned…

Alright, Cipher. I carried out my part of the deal, now it's your turn. Let's wipe out the human race together…

"Hey! Hey, kid! Wake up!"

Pacifica's vision came rushing back.

"Huh? I'm alive?" She shook her head. "How many times have I blacked out now?" She looked down, realizing she was sitting on the floor, seemingly unharmed. "Where AM I?"

"You're in the lab." Robbie's voice came from right in front of her. The robot stepped out of the shadows, dusting himself off.

"Robbie? Wait-you saved me?"

"Couldn't let anything happen to you. Not before I took your soul myself."

"What?" Pacifica asked in a quiet voice. The robot let out a humorless chuckle.

"I'll admit, I actually had some fun doing this thing with you. I felt like I was doing something with my life for once, instead of just being stuck inside a lab doing a job I hated. I mean, really. Helping the human on her way out of the Underground, joining her on this AMAZING journey. But you know, it just wasn't enough." He walked a little closer, and Pacifica gulped.

"If this is about forcing you to help me…" Robbie let out another humorless laugh, shaking his head.

"Actually, I was hoping you'd do that. I had a lot of fun leading you on-reactivating lasers, leading you around in circles-it was AWESOME! It's the most fun I'd had since I was tricked into being the Royal Scientist!"

"You USED me!" Pacifica gasped in realization.

"Well, duh!" Robbie threw his arms up. "Nothing against you-humans are pretty good in my book. But I just couldn't stay in that stupid lab anymore!" He gave her a hard glare. "All I ever wanted to do was be famous. Entertain people, you know? So I figured…what better way to fame than getting the last human soul to go through the barrier?!" A manic look filled his eyes, and Pacifica wanted to cry.

"I'll be the hero of the Underground." Robbie pulled off his lab coat, tossing it aside. "For once, I'll be a somebody. Everybody will know my name. And Wendy will be all over me."

"I…I…"

But for once, Pacifica couldn't find anything to say. Her closest ally had betrayed her. She felt like she'd been punched in the gut.

"Say your prayers, little girl."

A/N: Robbie you asshole! Though honestly, I think everyone familiar with Undertale knew this fight was coming. Yeah-again, I'm sorry the chapter's short and not that good. I've actually been trying to focus more on writing for a webcomic I want to get started on this year, so that's been my main writing priority as of late. But you guys know me. You know I wouldn't just ditch a fanfic. I intend to see this through to the end. And I can assure you that the next chapter will be longer.

Now then, how about starting the year off right, and leaving me some reviews?
