Welcome to Monster Falls
When a trip into the forest goes terribly wrong, Dipper and Mabel Pines are cursed and experience some...changes.
Dipper's now sporting antlers and hooves, while Mabel has some new fishy scales.
To make matters worse, the curse spreads to the town, slowly turning person after person into a monster.
Meanwhile, Bill Cipher takes pleasure in the town's folks dilemma, until he too, is unexpectedly affected by the curse.
But how do you turn something that's already a monster into one?
