Mabel x Robbie fan fiction (Gravity falls)

hi there, my name is scary kitty (not putting my real name out there for a reason) anyways i noticed there are not a lot of Robbie x Mabel stories out there so for the people who actually like the ship then they can read mine or what ever but if you don't like this ship then plz just don't read it. it doesn't make any sense to read a ship that you don't like just to comment mean things about it. so plz no mean comments or you will be reported. i do not own the characters just the plot line all rights go to the creators of gravity falls. anyways on with the book!! (By the way this is sorta an apocalypse book also i had started on this before i had watched the season finale, weirdmagetton)
