Monsters within is now a trilogy! With an alternate ending to the one before. No need to re-read the others... I'll do a short recap. NOT BILLDIP. JUST MAKING THAT CLEAR. ---------------- Dipper and Mabel Pines are doing great since they turned into monsters! Just great. Other than their developed hate for humans. Most monsters gave up trying to return to their regular life. Even the twins. They were abandoned by Bill in their younger years. He was supposed to heal them; That was the deal... but he left. Why'd he have to come back?
