Dipper stirred in his sleep. No matter what, he couldn't shake the ominous feeling he was being watched. He had been feeling this strange feeling for days now. Word around town was that some creature was stalking the woods and streets at night, and being Dipper, this meant he had to know what was happening. Dipper glanced at the clock, a red 3:52 glared back at him. Dipper wasn't very tired, so he decided now was as good a time as getting up to start his chores. He got up from the bed, made sure Mabel was asleep, and slowly opened the door and walked downstairs.

He finally got to the bottom of the stairs, and realized how thirsty he was, and headed into the kitchen. He opened the cupboards, filled a glass with water and drank. He looked up from the glass, looking out the window, and dropped the glass in fear. Against the window, peering in at him, was a tall creature with a wolf's head and legs, with long arms, and covered in fur looked at him. Its eyes were milky white and seemed to glow in the early morning darkness. It appeared to be some kind of wolf, but part human. It growled at him, baring its fangs, and Dipper backed away. Dipper looked around for anything to help him, and thought about yelling for help, but dismissed the idea. By the time anybody got to him, the creature would be long gone. The creature snarled, but quickly climbed out of view.

Walking back upstairs, Dipper slowly opened the door to look at Mabel. "Good," he whispered to himself. She was okay. Mabel and Dipper were now thirteen. Mabel and Dipper had grown a bit; Mabel had recently had her braces removed. Dipper smiled when he saw his twin was safe, and grimaced when he heard glass breaking downstairs.

Dipper slowly walked back downstairs, and looked around, and saw that the kitchen window was smashed open. He could've sworn his heart stopped. He nervously glanced around. "Where is that thing?" he thought. After searching the room quickly, he exited the shack using the gift shop door, looking for what he'd seen. A growl alerted him, and he looked around frantically, until he looked up to the roof. The creature dropped down, in front of him, and swung a claw. Dipper narrowly dodged it, and immediately darted to the Mystery Cart. He opened the compartment on the dashboard, fishing out the keys, and wasted no time to start the cart, speeding off into the woods, the hulking monster behind him.

Ten minutes of nonstop driving into the woods, and Dipper looked behind him, halting to a stop on the top of a hill. He concluded it was safe, and sighed in relief, taking a moment to rest. He started up the cart, and felt something land on top the cart. Something big. The cart slowly pushed forward, and started to fall down the hill, gaining speed. The creature from earlier punched through the roof, and held Dipper by the collar of his shirt, as the cart sped, it hit a bump, shaking the cart, and Dipper's shirt collar tore, and he fell free from the cart, his hat falling off. He tumbled to a stop in the thick grass, and looked at the cart. After falling off a small cliff, about twenty feet, it had burst into flames, it was totaled. "Grunkle Stan's going to kill me," Dipper thought aloud, and walked in the direction he thought the Mystery Shack was in. It took ten minutes for him to fully realize he had no idea where he was going. Worried, he tried to look for a place to rest; he'd find the Shack in the morning. He settled on a cave that he found in the forest, he lied down, and, after getting adjusted to the hard cave floor and the horrible cold, he drifted off to sleep.

Dipper heard the ominous low growling that could only belong to a certain creature that he thought was dead. He sat against the rock, praying it didn't see him. Dipper quickly pulled out 3 and began to read. "Zombies? No, gnomes? Definitely not…" Dipper flipped through the pages until he found what he was looking for. "This is it! It's a-"suddenly, Dipper was picked up by the throat. He saw the creature holding him up; it raised its claw, and swung.

Dipper's screams were heard throughout the forest.

Mabel's POV

I woke up to see Wendy was trying to wake me up, she looked panicked. "Mabel, you have to get up, c'mon, wake up!" I slowly opened my eyes and sat up. "Huh? What's going on?" I asked. "Dipper isn't here! I've looked all over for him!" Wendy exclaimed. Suddenly I didn't feel very tired. I was incredibly worried. "Are you sure? Dipper could just be out doing his morning chores, probably hanging up more signs?" I asked. "Nope, he's been gone since… well, before anyone woke up," Wendy said. "Well, what time is it?" I asked. "It's two thirty, the Shack's been open all day, but no sign of Dipper," Wendy said. An idea popped into my head. "Let's call a search party! I'll call the sheriff," I said. I got out of bed, and ran downstairs, Soos was looking everywhere. "Seen Dipper anywhere, dude?" he asked. "No," I said simply. I slowly got to the phone, dialed 911, and waited. A female voice picked up the phone, she sounded quite relaxed. If only I could feel relaxed in any way.

"Hello, Gravity Falls Police Department, how can I help you?"

"My brother hasn't come home all day, he was gone before anybody woke up," I said.

"Alright, who am I speaking to?"

"Mabel Pines, I'm at the Mystery Shack,"

"Ah, I see, I'll alert the sheriff,"

"Thank you! I need to make another call," I said.

"Have a nice day,"

I heard a click, and hung up the phone. I reached into my pocket and pulled out my cell phone. I called Grenda first. "Hello?" she asked over the phone. "Hey, Grenda, it's Mabel. I need your help, come to the Mystery Shack, I'm calling Candy to tell her the same thing," "Sure, Mabel, be right over," she hung up, and I called Candy.

I heard a knock at the door, and Soos ran to the door and opened it. Sheriff Blubs walked in, and Deputy Durland followed behind him, shutting the door. Sheriff Blubs sighed. "What is it this time, another wax figure murder, a psychopath?" he asked, he sounded a bit bored. "It's serious, my great nephew's missing," Grunkle Stan walked downstairs. "You mean the kid? Don't worry, we'll find him," Blubs took a drink of his coffee, and the doorbell sounded. "I got it!" I said. I opened the door to see Candy and Grenda standing there. "Mabel, what is it you called about?" Candy asked.
