Dipper wore a hooded red flannel sweater. His brown hair and growing stubble were only visible from up close, unlike his reflective eyes that could be seen from miles away. He stood still on the road, ears folded down and eyes wide. He truly was a deer in headlights.

------------

A blue triangle shaped vortex revealed the cosmos. Dipper shivered and backed into the sleek, blinding white wall that stood behind him.

"Heya, Pine Tree!" Bill said, somersaulting from the portal and flicking his wrists so colorful, flashy fireworks sparkled around them. "Need help getting back to normal, I mean, it was a part of a deal. Deals are binding. To a demon."

---------------

To this day, Dipper regrets not having kicked that demon's butt. Except he was in a situation a bit too irrelevant to think about that.

Fwoosh. And the car was taken away, drifting on a wave of lake water. His ears stayed down as he shook his head out of his daze, only to be greeted with Mabel, his mermaid sister. Riding her magic body of water. "Don't worry bro, I got yo back." She pounded above her heart twice.

He pounded back. "Grace from the forest, Mabes. Thank you." He bowed, his deer butt in the air with one foreleg straightened and the other bent in an upside down L. His head ducked down so his hair grazed the road.

"Okay, okay you damn hippie." She laughed as she started to drift her floating pond away. It sparkled in the moonlight and carried two equally sparkly fish. One pink, the other purple. "Don't have another one of your so called 'Accidents'."

Dipper shot up and stiffened, glaring at his sister. He stomped his forehooves aggressively and angry vines shot through the top of the car. "ONE TIME, MABEL! I WAS 13. WE JUST GOT OUR POWERS... and it was justified." He rubbed his arm, guilted as his eyes watered.

"You're still guilting about that, bro?" Mabel smirked and ran her hands down from the sides of her chest to her hip, playing with the excess skin where it connected. "Since I learned how siren-y my powers were I've come to realize something, bro." She stopped playing with her skin and put her hands on her hips. "Humans aren't worth the guilt."

She zoomed away. Dipper sighed, wincing at the blood that trickled and dripped from the car wreck. "... but we used to be human." He turned towards the town and glared at his hooves. "NOT THAT IT MATTERS!" He yelled, stomping and ruining the road, tearing it with vines and shrubs and trees. He made it seem like that's where the road ended. It was justified. They were in monster territory.

He sighed at the old, vined up 'Welcome To Gravity Falls' sign. So much has changed...

------------

"Too bad demon deals don't count on humans. Like. Me." Bill smirked. "What about your hypnotic 'spell?' You ask? I got my magic back, stupid. No effect. Nice try though." He took a few steps closer.

"You butt! Change us back!" Mabel yelled from the fish tank that was built in the wall.

Bill hummed thoughtfully. "Nah."

The demon smiled at the young cervitaur's trembling, fearful expression.

"I like you just the way you are."

------------

"Hey!" A voice called from the road he just cut off. Dipper stopped in his tracks and glared at the figure, past the brambles, that was running towards him. It looked like he had his family waiting in his car. He snuck out enough for the man to stop and notice something wrong. With a flick of his wrist, the car and family were lifted with thousands of flimsy vines.

The man seen red eyes staring at him, hostile and feral in every way. The figure stood up tall. It looked like it should have had fangs or horns. He heard something shooting in the air and the screams of his family. He turned to the car.

No more accidents. None of these are accidental or have to be justified. Not anymore. The car dropped onto the man with a stomp of Dipper's hoof. With another, the car was pulled into the cracking road, never to see the lights of day again. Nothing he did now had to be just.

He wasn't human. He was a monster. Like all the monsters... they had to stick together, eat the weak and breed the strongest. They had to survive in this way of living and he had to accept that humans were no more than fresh meat or another threat. Either way, humans weren't wanted as visitors.

------------

"Have fun with your government friends by the way, they'll turn you back in the most painful way possible. I'm sure of it." Bill clapped and he disappeared. They never seen him again after that.

"Dipper" Mabel called. Her brother trot closer. "Find out where Bill got his magicmawhatzit, and go get some! You can break us out of here!"

Dipper shook his head. "R-right..." He sighed. "I think I'm mad, but will miss Bill at the same time... he was so easy to pick on as human..."

"Just go!"

------------

Dipper walked back to the shack. Although Mabel will be proud... he's sure the Stans will disagree with his acceptance. As a cervitaur he's not as dangerous as predators, but he's not exactly safe either.

Hood up, he walked into the shack. She sighed when Stan stopped him and ripped his hood off, taking him by the cheeks and staring at him in his red eyes. "Dipper, what did you do to cause this?"

The cervitaur tore away aggressively. He stomped and roots grabbed Stan by the feet and hung him upside down. Dipper stomped upstairs, vines appearing with each step. They covered the stairs and most of the walls. "I don't want to talk about it."

--------------

Dipper galloped through the building, avoiding stepping on all the knocked out guards. He stopped at the room filled with jars of what looked like the night sky. He grabbed as much magic as he could carry, taking the time to make the best weave basket he could.

He galloped out, but stopped when met with the now awake guards. He gulped. "Please, put the magic down, we don't want to hurt you."

"You killed Stan!" Dipper yelled.

The woman stared at the cervitaur's hurt expression. "Dipper, that's what the girl called you, right?"

The boy gulped, reading the labels of the magic bottles. Wind, Water, Nature, Enhanced, Portal. "Now, Dipper we need you to-"

Dipper dropped the one that read portal, letting it smash so he could het his feet in it. It was disorienting at first. Like he just got off the spinner at Funland. He could almost hear the spinner, almost like he was there.

His eyes came into focus and the guards were gone, in front of him was a portal he looked down to see the top of the spinner. Oh. The portal closed. He thought of Mabel and another opened in front of the aquarium. He smiled as his tail wagged happily. He bounded through, Mabel smiling brightly. "Get me out of here, bro!"

He nodded, putting down the jars and sorting through them. "Dog, glass, hypnosis, transformation, fear, flight, nature, water-"

"Just pick nature." Mabel suggested.

"Oh ok, it's just I already..."

"Oh, yeah, okay."

Dipper shrugged. "I'll use it anyways."

"Do you like... drink it?" Mabel asked.

Dipper shrugged again, taking the top off. "I guess?" He poured most of it into his mouth. He moved his tongue around in his mouth, trying to get a good taste. "Not ba-" His eyes glew gold.

Mabel looked left and right. "...Dip? You okay?"

Guards ran into the room and Dipper glared at them, eyes red. Thorned vines sprout from the ground and wrap around their necks, getting tighter and tighter.

He looked back to Mabel with calmed, gold eyes. She banged on the glass, looking towards the choking people. "Bro, stop suffocating them! THEY'LL DIE!"

A vine whipped out and pierced the aquarium glass. Sevral others did the same. He wasn't listening. The glass cracked and broke. It released the water that soon spilled everywhere, the vines weaving and making a net for his sister. One vine reached for the water magic and handed it to her, another reached for the nature one and gave it to Dipper. Dipper poured the rest of it into his mouth as more vines grew from the ground. Mabel stared wide eyed.

Her brother was going to go crazy with that. He wiped his mouth and breathed. The guards' necks snapped and the net began wrapping around Mabel. Trying to breath and choking on the air, Mabel drank a bit of the potion she was given. The water that spilled to the floor rose and she rotated it like a blade, cutting the vines successfully and escaping the net.

She flopped on the floor and cupped her hands to her mouth. "Bro! Stop! Calm down or something! Think about it! You'll never forgive yourself!" She said, trying to get his attention.

He turned around, red eyed and vines whipping around at his will. "Humans aren't worth the guilt." He growled before getting hit in the back of his head. He collapsed and the vines shriveled up and died.

Stan dusted off his rocky hands. "Sorry, kid."

Mabel gasped, creating a bubble of water over her face. "Stan!"

The Gargrunkle looked around. "What happened?"

Tears were in her eyes as she hugged her uncle.

-----------------------

Dipper sighed as he meditated. He laid his deer body on the ground, breathing in and out. He reached in front of him and pet the midnight blue leaves of a seasonal plant. His room was covered in vines. An indoor forest, if you will. He has trees growing from under the house bursting through the roof so he could have a tree in his room. He was glad Stan let him keep it.

A knock of the door and the plant flinched away from Dipper. His eyes were red when he opened them. He took a breath and they were their usual brown. He got up and trotted to the door. Once he opened it he frowned and closed it, but a paw got in the way. He sighed, opening it up again.

"Dipper, why would you do that?" The sphinx asked, slapping him on the side of his head.

"Do what? Not answer a riddle correctly or something?" Dipper pouted, the plants in his room slinking back. "What new thing did I do this time, Ford? Did I lose something? Did I release another disease? Oh, or maybe I killed a car full of humans." He huffed, eyes going red as the plants in his room whipped around. He slammed the door shut and frowned at his room. He breathed and everything calmed a bit more.

Ford was speechless, but huffed as he turned his back. "This is the thanks I get for trying to help..." He pounced downstairs to the basement. Not before clawing at the vines that his brother was trapped in.

Stan sighed as he got up. He looked around and seen Dipper's plants aggressively growing like weeds and killing off other plants. He opened the door and went outside, he climbed on the roof and sat. He waited for predators. He waited for something that would try destroy his brother's home. It seemed that's all he did these days. Wait.

He looked through Dipper's window to see him battling with a sturdy vine. He looked afar to see Mabel dragging a human into the depths of the lake. He knew Ford was in the basement, looking for the cure Dipper could never find.

At least they were safe.
