In the hazy space between wakefulness and sleep, Mabel says goodbye to a new-ish friend. (#3 of the Twintale series)

Having awakened in an underground location with no means of escape, Dipper and Mabel begin to search for freedom. However, they soon discover that this underground is not what it seems. For along the way they encounter new allies, and new enemies that will either bring them closer, or tear them apart.

Mabel Pines did not know what to expect. She had went on a search for her missing family member only to fall into the Underground, which was full of monsters. Follow her as she embarks on an accidental journey, filled with determination.

Dipper pines is an adventurous boy who has no idea that his life is going to get a bit more adventurous... rated T for dark themes and maybe profamity

Omega has a rough time in Gravity Falls, conquering fears among them. She tries her best not to screw anything up but always dose, life was just unfair. Until she met someone, then her life changed forever.

As far back he could remember Asriel Shepard was just a regular kid from the sleepy town of Gravity Falls, Oregon. But one summer he met a pair of twins who drew him into the mysteries surrounding the town. As he gets drawn into the adventures of the Pines Twins, Asriel is going to learn that there is a lot more to Gravity Falls, and himself, then he ever thought possible.

There once was two races ruling over the earth. Humans, and monsters. One day war broke out amongst them, and the humans were victorious. They shoved all the monsters they could into a mountain cave sealing the in with a spell, but what happens when a demon shows one human the truth of what has happened? \/\rated teen for no/\/

This takes place after gravity falls weridmegeddon and undertale, a new threat has emerged itself to resurrect old foes. But what is this creature, and will he be stopped. Undertale- Toby fox Gravity falls- Alex hersh D GDUN GDB LV FRPLQJ, ZKH VNB LYHUCIRZP TLWK GXVW DQG VFUHDPV. \

"Howdy!" the flower cheerfully called. "My name is Flowey. You two must be lost."

It's basically Dipper and Mabel reliving the events of Undertale. Maybe with a few twists and turns if I can actually make myself add more chapters.

When Dipper, Mabel and another young girl fall into the underground of Mount Ebott in Gravity Falls, they must work together and make their way out the Underground, and get home. But things are not what they always seem, as a flower and certain demon stalk them from afar... My first story. Based around episode 15 of season 2. I will refer to Frisk as female.

I know the name is kinda stupid, I'm not good with names. I might change it after a while. Where is Mt. Ebott? Gravity falls of course! With the monsters free they must help get rid of the trouble that they accedentaly cause, indangering Frisk and Gravity falls.

Twins Frisk and Chara are sent to their Great Uncles Sans and Papyrus' place in a town called Under Falls for the summer. They think it's going to be boring, but they discover that in Under Falls, nothing is what it seems.

Mabel Pines, the sweet girl who was good and kind to all. That lying unicorn said that there was darkness in her heart but we all know that's not true, right? After all this is Mabel we're talking about... Right? I own nothing, please review! One-shot!

A story about the supernatural world of Gravity Falls told through a style comparable to Diary of A Wimpy Kid or Kane Chronicles./ Dipper is convinced that something other than the norm is lurking in the woods. Mabel is too caught up in her crushes to notice./ Frisk and Flowey keep a journal to record their time on the surface./ Post true pacifist and DD&MD. (Fem!Frisk)

Sans et l'Ombre s'affrontent. Le sang teinte les pavés qui composent le sol du corridor. Mais parfois on ne peut survivre sans aide.

Post - The Inconveniencing AU! Two worlds collide...so much genocide...will mercy be on the menu?...or will mercy only cause more suffering? For better or for worse, the Mystery Shack gang is about to find out! Dipper X HAREM!

My opinions on Gravity Falls and Undertale Ships! Because...I don't know! Yay! Well actually Bill and Asriel will also give their opinions on ships. And sometimes other characters (If I want) so send us ships! Rated T because possible swearing.

Dipper and Mabel are now 14 and they move back to Gravity Falls. They expect a relaxing summer of hanging out with their family at the Mystery Shack. It doesn't happen that way though, as a boy named Frisk suddenly comes into their lives. It all goes downhill from there. I do not own Gravity Falls or Undertale

In my opinion, this is the cutest couple this crossover has. Slight Mabpyrus, and some Sans puns.

After Omega going rouge and is brought back to the underground lab, Ford decides to understand her a bit more.

A king sits alone in a garden. Easily manipulated, easy target. Perhaps this time, gold will reign over all.

My past consumes me as I am in deep suffering thanks to an Old Scientist named

I wind up waking up in a underground lab, fearful, but I was ready for what was going to happened. But not this though.

Getting a Pen Pal is a normal thing. But when Dipper, Mabel, Steven, and Frisk all get each other. They learn that the things in their own little world aren't the only weird things. / Undertale Gravity Falls and Steven Universe cross over!
