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?

One day after falling into a mysterious pond in the middle of the forest [no thanks to Mabel] the twins wake up no longer human. When Ford finds out he tells the twins about the war between humans and monsters. After that he calls the one person that he knows will take good care of them and will protect them. How will the mystery twins react when they find out that their new caretaker and foster brothers are skeletons? (A/n: Sans is 13, papyrus is 6 and the twins are 12)

Everyone knows the famous Gravity Falls AU 'Monster Falls'. After one day when Dipper falls into a strange river, everybody in Gravity Falls turns into a strange monster! How can they fix it and what weird adventures will they go on? Also, Gravity Falls doesn't belong to me!

I've seen SO MANY of these and I wanted to make one. So here's my "perfect" mystery falls fanfic. I will update at least once every other day. I hope. Ciao!

Mabel, Dipper, and Wendy find a strange river- it's the clearest river they've ever seen, and it tastes sweet, almost addicting. When they swim too long and Stan has to come find them, finding the river in turn, he decides to bottle the water and sell it. What they don't know, is that Stan's sold water to the whole town from the Deum Flumen Cantata, Fluvius Cantata for short, and even Ford doesn't have the cure for it. _____ I just have to say, I think how they get back to being humans is the best solution of all the Monster Falls, I'm just saying. Prepare for laughs and easter eggs!

This story also takes place after Dipper and Mable went back home. Deerper is now in Human Dipper's body and Human Dipper is in Deerper's body. Enjoy! -3-

It all started when they fell in the river. ______________________________________ (Cover Art: https://66.media.tumblr.com/92b19912e502ed79da52fe81a9141de6/tumblr_nxfczeGVfa1r9ee9go1_400.png)

It looks like an ordinary day for Dipper and Mabel Pines, until they stumble across a strange river. When people start changing all over town, it's up to them to find a way to escape the monsters within. (Monster Falls AU)

I really don't like the way my other Monster falls book is going, so i'm gonna restart it completely, meaning I also might switch the monsters the characters have (For example: Mabel will be a mermaid in this) And i'm including Bill (NOT BILLDIP: I REPEAT! NOT BILLDIP)
