Halfa Pines Twins AU! (Art by my sister, @goldenpaperscissors)
The Pines twins are the Fenton’s cousins on their mom’s side, leading them to be visiting the Fenton residence just a week or so before their twelfth birthday. Unfortunately, this happens to be the same week that the Fenton’s complete the ghost portal. Gosh, what bad timing.
Jazz takes both sets of parents out to dinner, telling Danny to watch the twins. The mistake on her part was believing that Danny had a will strong enough to resist two chaotic eleven year olds. When Dipper said he wanted to get closer to the portal and Mabel wanted to see more of that shiny ectoplasm, he stood no chance. At least he made them put on safety suits?
