12 in Gravity Falls

So hey this is a story of something I made up so basically this is 12 Forever with a slightly different plot and Gravity Falls characters. Mabel is Twelve, Dipper is Shane, Robbie is Tristan and Bill is Buttwich have fun reading and check out Twelve Forever on Cartoon Network it's awesome and really needs to be greenlit!

I only own the plot changes.

I am not the owner of Gravity Falls or Twelve Forever
