a continuation of a gravity falls fanfic I was reading

In a world where Bill didn't fall for the Pines trick and the fight for survival wages for three years, a war-hardened sixteen-year-old Mabel Pines is sent back in time to a few days before their fateful trip to Gravity Falls. She does all she can to prepare for the arrival of Bill while trying to save her family.

Summer is over and for Pacifica a new Chapter in her life is beginning.

he's counting the days. he knows he shouldn't, he knows he should be living his life in the moment, but there's something waiting for him at home, and he can't wait for finals to be over.

Dipper and Mabel haven't been to Gravity Falls even once in three years. Now, as 17-year-old teenagers, they return. Unfortunately, weeks before departing for the town, Dipper is unexpectedly turned into a vampire. He must not only learn to control his abilities and his blood lust but also prepare for even more threats... And Romance? Dipper/Harem

Der Sommer ist fast vorbei und für Pacifica beginnt ein neuer Lebensabschnitt. Wird sie diesen meistern können?

Dipper and his wives and Mabel have been immortal for 40 years now and Dipper is still as invested in his work. Wendy and Mabel have an idea to get him to loosen up. A trip to New Orleans for Mardi Gras. It should be fun. They also meet an unexpected 'friend'. Rated M for explicit content.

just some ideas I was kicking around

There were no faeries in university. There were no gnomes, centaurs, or unicorns either. Dipper hadn't seen any sign of weirdness anywhere, really, but Gravity Falls, and some part of him feared that one summer was last he'd time he'd touch the supernatural.

After going through a cave, Wendy and Tambry's bodies grew in all the great spots. Dipper couldn't keep his eyes off of them while his sister offered them and him to go to the lake, alone, in their swimsuit and bikinis.

When Dipper and Mabel find a time tape in the middle of nowhere, Mabel accidentally takes them back to the year 2009. Now with Time Baby dead, the device can't work anymore. Will they be able to fix the time machine, or will they be stuck in the past forever?

The hidden story of what you didn't see after the main events of "Boss Mabel" and before the post-credits scene. Stan shouldn't have taken that chance as Mabel makes his remorseful dance.

After the Pines twins are tasked with cleaning up the party Mabel uses the copy machine to make clones of herself to lessen the burden, and gets the idea to use the other Mabels to move along Dipper's crush on Wendy, and things spiral out of control. (One shot)

This is a story about tacos and cats

Roleswitch AU. Bill Pines didn't ask for much, he just wanted to live a carefree life in Gravity Falls and party whenever he could. He certainly didn't ask to be the plaything of the same glitter crazy demoness that terrorized his childhood in order to save his brother. "Life is just full of surprises, am I right Corn Chip?"

Dipper Pines has grown up. Now a detective dealing with crimes involving the paranormal/supernatural, he finds himself traveling across the country with a recently bankrupt Pacifica as his helper. What kind of supernatural mysteries will these two be taking on together? Dipcifica COVER ART DONE BY MariusWales. Look him up on Deviantart(dot)com

Dipper and Mabel are home from their eventful summer, and are happy to start the new school year after reuniting with their best friend, Samuel. But what happens when a vengeful Bill Cipher sets his sight on that kind-hearted boy...? And what will this encounter lead to for the twins...?

...doesn't always stay in Gravity Falls. Especially when the former rich girl somehow becomes a teen idol and hunts down Piedmont's one and only supernatural expert. This cannot end well.
