Spoilers for after Undertale and after Gravity Falls! The twins are coming back to Gravity Falls for their winter break. However. The mountain just by Gravity Falls had a strange event a few weeks after the twins left. Monsters from the fabled "Underground" started coming out of Mt Ebott. With their savior, Frisk. Now Frisk and their monster family live peacefully in the nearby town of Gravity Falls. What shenanigans will the twins get up to this time? What will they discover? *This takes place after Gravity Falls' Finale and Undertale's True Pacifist ending!* The original Gravitytale idea as well as the intro music used was made by the amazing Jeffrey Watkins. Check them out on Youtube and their story on AO3! I thank them for inspiring me to make my own fanfiction. This is my first story and first time writing a story, it might not be any good, but do enjoy!
