1 ∆ Killer and his pine tree

Dipper and Mable the twin heirs to their Grunkles thrones. Mabel is excited to be in the throne, ruling and hosting balls. Dipper is less excited, for. multiple reasons:
1. He doesn't want to be in charge of people's lives
2. He isn't really well liked
3. THEY'RE GOING TO HAVE TO MARRY SOMEONE

he's a bit afraid of love and the heartbreak that come with it.

But a dark figure suddenly starts stalking the castle, the figure may be out for something or someone. But who? (WE ALL KINDA KNOW POLAR!!! STOP BEING SO OBVIOUS!!)
