Chapter 2

Fluvius Cantivius

Dipper's POV

I awoke in a sweat. I looked down and saw my deer legs and was confused. And then it all came back to me. The Fluvius Cantivius, The transformation, and Mabel touching the river. Ilooked over to see what she was, but she had disappeared. I wondered where she went when I realized something was behind me and I didn't want to hear him.

"Hey there buddy!" He said.

"What do you want Bill?" I asked aggravated that he was here.

"I just want to say the whole town will end up drinking this and turn into monsters themselves!" He replied.

"Wait, what? That's going to happen?" I asked him.

But when I turned around he was gone, and then I awoke out of the Dreamscape. I woke up panting like in the dream. I looked to the left to see Mabel as a...

Mermaid?!

"Oh crap" I said. I woke her up and had to bring her to water, not in the Fluvius Cantivius, she already turned into something supernatural. But at the lake people would freak out by seeing us. We just went to a pond nearby and explained that Bill came in my dreams and said that everyone would drink from the fluvius Cantivius for a water supply, and when I said that, she freaked out.

"What will happen to Stan, Soos, Wendy, and everyone?" She asked filled with dread.

"My guess would be that they become monsters like us" I answered.

"Wait, what are we going to tell our parents?" She asked.

"Oh crap, I didn't think of that. We have to find a cure ASAP!" I explained.

"Well, I can't come out of water" Mabel said.

I'll fix that... I thought. I waited till night to go to the Mystery Shack, get a growth flashlight, and a hamster ball. I came back, filled up the ball with lake water, grew it, and made a ball for Mabel to use. I got her in there and she tried getting around, but managed to hit a few bushes. Good grief... I thought. I then realized that there were footsteps, so we ran to cover. It was Stan, Soos, and Wendy. They started talking about how they could use the water to make more money. They tried tasting it to see if customers would like it.

"They just drank it!" I hissed under my breath.

"Hey! Who's there?" Stan yelled in our direction.

"Run!" I hissed at Mabel. We started to run, but running with the lower half of a deer is not easy, remember that. We got pretty far and didn't hear anyone following us.

"Phew..." I said.

"Uh, Dipper?" Mabel finally spoke.

"What?" I asked. She pointed to our right to see Wendy looking at us open-mouthed.

"But, what the, how ,who?" Wendy was at a loss of words and then blacked out.

"That must have been from the water." I said about the blacking out.

"And from awe." Mabel added.

So, we would have to wait to see what would happen to them. It was just then when we heard Stan and Soos calling Wendy's name.

"Oh no!" I said. We brought Wendy's body into a cave and stayed there. A while passed and didn't seem like anyone was coming. I just closed my eyes, and drifted off into sleep.

That's it for this chapter folks!

Hope you enjoyed!
