The beast did not expect running on all fours to be an exhilarating experience. He was currently being proven wrong. Now covered in brown fur with a snout and a long bushy tail the beast was more canine than man, and he was loving it. No longer was the worried boy in control, a wild beast was now at the helm. Running through the forest the beast could hear and sense every little sound and animal, and it was amazing. Every little thing was a new detail, and there was so much to explore. The cool breeze was so refreshing through his fur, the air washing it over. Having fur was admittedly a great feeling, it just felt so nice and warm. Speaking of nice feelings there was nothing quite as special as running like an animal. Although a civilized boy most of the time the beast could not deny the thrill of letting all his anxieties go away and just get caught up in the thrill of the hunt. While he wasn't particularly hunting anything the thrill was still there, his senses working overtime. His hearing could pick up anything, his smell caught scents he could never have picked up with his puny human nose, his eyes picked up everything in the best possible quality, and his mouth was now full of sharp fangs and a long tongue. The constant running proved to be too much however and the beast stopped to pant, his tongue hanging out. As soon as he stopped one thing caught his attention, its beauty truly speaking to him:

The full moon.

Just from a single look the beast knew immediately what the moon was. It was his master, the reason he was the thing he is now. So he did what he knew he had to to honor it: he let out a long victorious howl. Raising what were now paws he stood on his hind legs, taking in the euphoria of the howl. It felt like he was letting out all his emotions to a dear friend, and it was truly life-changing. However something unexpected happened, instead of a glorious howl it soon ended with a small bark. the beast was confused. This was a glorious tribute and as such was deep and meaningful, why was the bark of a much lower animal coming from him? His thoughts were interrupted by something far more humiliating: a small yip escaped his mouth. Horrified the beast put a clawed paw over his muzzle but even more came in response. Just as he thought it couldn't get worse more and more yips seemed to come out, until he wasn't howling at the moon but lightly shouting at it. The beast felt defeated, and hung its head in shame.

And that's how Dipper found himself suddenly jolted out of his dream and gasping and panting in response. The boy was quick to look at his hands, and was satisfied to see that they were covered in flesh and not fur. A quick scan of the body confirmed that the rest was hair free. With a sigh of relief Dipper returned to his sleep, and the rest of the night was peaceful.

The next morning started with a stretch and a groan, as Dipper slowly lifted from his bed. Blinking he felt dazed, like he didn't want to get up. As much as he wanted to shuffle into bed and fall back asleep his gut told him that he needed to simply get up and face the day. Sighing he leaped out of bed, noticing that Mabel's was empty as well. Thinking she was just playing with Waddles he ignored it, but just as he was thinking a strange feeling overwhelmed him. Right in his back something felt off, like there was something rubbing against him. He began to move his hand over his body, determined to find where the sensation came from. Once he did however, the look on his face clearly showed that he wished he hadn't. His hand had reached the one place he didn't want to look... his behind.

"Nope. I am not touching there" Dipper said to himself.

"What are you talking about?" a cheerful voice from behind suddenly asked.

Startled Dipper jumped, a small yelp coming from his mouth. Turning around he saw Mabel, head tilted in confusion. As thoughts ran through his head Dipper reached one conclusion: he needed to find out why a certain area was bothering him, and his best option was to have someone look. Dipper sighed, not wanting to go through with what he was about to ask.

"Mabel... there's something bothering me. So if you can look at... my behind, just to check, I would appreciate that" said Dipper.

"You want me to check your butt?" asked Mabel.

"Its nothing weird there's just something bothering me and I need to know why."

As confused as she was Mabel simply shrugged. As she motioned for certain things to be revealed Dipper sighed and pulled down his pants. Mabel then took a tone that was far more insepective than Dipper would have wanted. Taking a good look Mabel stared attentively, focused solely on seeing if there was anything that stood out. After what felt like an eternity for Dipper Mabel stood up.

"You're fine. I mean, you asked me to check your butt so maybe not completely fine, but it looks normal" replied Mabel.

Although he didn't know what to say Dipper was admittedly thrilled to have this over with. Smiling he wrapped Mabel into a warm hug, and she was obviously caught off guard.

"Thank you thank you thank you" Dipper said quickly.

"Uh... you're welcome?" said Mabel, not sure how to respond.

Dipper let go, and saw Mabel's discomfort, causing his mood to drop.

"Did I do something wrong?" asked Dipper.

Mabel cringed internally, but decided to speak her mind.

"No no you're fine. Its just... this energy is a bit weird" said Mabel.

Dipper seemed caught off guard, but kept a relatively happy expression.

"Oh sorry its just... I'm feeling great right now. There's a lot going through me, you know? I just... its great" said Dipper.

Mabel smiled weakly, not sure what to say. Dipper didn't seem to catch her feelings, and began to speak abruptly.

"You know I should probably get going, Stan probably wants me" said Dipper.

"Yeah you... you do that" Mabel said weakly.

With enthusiasm Dipper ran off like crazy, faster than Mabel had ever seen him run. Looking at this, Mabel put a finger to her chin in thought.

"Ok, something's going on."

Meanwhile Dipper's enthusiasm had not stopped and he ran into the shack. Soos, Stan, and Wendy were in all attendance, each in one specific area. While Soos and Stan simply stood there, not noticing the young mystery solver dashing in, Wendy took notice and immediately put on a more panicked expression.

"Shit shit shit" Wendy said quietly to herself.

As soon as she saw Dipper Wendy's mind went into panic mode. She didn't know how much he remembered, but she knew she was to blame. From what she had heard from Stan the signs were there. Canine traits, an increase in excitement, and a sudden snap. He was one of them alright, and it was all her fault. Her head sinking into her arms the redhead was in a permanent funk and wanted nothing more than to be left alone in her misery.

"Hey Wendy!"

Jolting up Wendy saw Dipper in front of her, smiling wide. Her brain went into full "What the fuck do I do now?" mode, and she felt doomed. Scanning around the area rapidly Wendy had no idea what to do, and just did the first thing that came to mind. She let out a startled high pitch stream, one that caused Dipper to fall on the floor from the impact. Hearing a thud Wendy looked down at the young boy and mentally cried.

"Oh god Dipper I'm so sorry, I never meant for this to happen! It was just... ugh! Please please please don't get pissed at me" Wendy pleaded to the unconscious boy.

As it looked like it was falling on deaf ears Wendy began to break down, sobbing uncontrollably. As she continued however Dipper's eyes began to open, and he looked at Wendy in a dazed state.

"Wendy? What happened?"

Immediately Wendy stopped crying, and looked at Dipper with relief. Half weepy half smiling Wendy looked at Dipper with pure joy, but she took on a more serious expression when she saw Soos and Stan were staring at her. Leaning down she looked at Dipper, with a no nonsense down to business look.

"Dipper, I can talk to you about this tonight but listen very carefully. I fucked up, and I'm sorry. You're something else now, but I can help you with this. I don't know how much you remember about last night but I'm sorry. Tonight. See me."

Wendy then looked at Dipper, wanting to make sure he had gotten everything. When she was satisfied she nodded and began to walk away, albeit with a look of concern on her face. As soon as the redhead left Dipper just stood there, unsure what to do. This didn't last long however as a loud cough was heard from behind. Startled Dipper jumped up in terror, and began to hyperventilate while moving backwards.

"Geez kid calm down its just me."

Immediately recognizing the voice Dipper felt a sense of security, and looking up confirmed that it was indeed Grunkle Stan, who looked weirded out.

"Oh sorry I..." said Dipper

Before Dipper could even finish Stan handed Dipper a mop.

"Look the statues are starting to reek so go clean them so that the smell doesn't interfere with the exchange of money. And do a good job, I need this" said Stan, not really caring much about detail or grace.

Understanding what he was told Dipper simply nodded, and Stan was on his way. Sighing Dipper took the mop, but a thought soon struck him and left him paralyzed: he wasn't told which statues to clean. Granted this shouldn't have been much of a problem but due to the number he had no idea just which ones needed to be cleaned in particular. The boy stood there, unsure what to do, when he picked up a scent.

He could smell dirt.

He had no idea how, or why, but frankly he didn't care. He had a job to do and he found a way to do it. Sniffing around he was determined to find the statues that needed the most cleaning, and his nose was like a GPS for it. Taking in the scent Dipper put his nose to the floor, determined to find what needed to be cleaned. Although tempted to just go on all fours Dipper got up, having the scent, and walked towards the statue. It felt like the scent was intoxicating, drawing him towards the statue as he could do nothing but follow. As soon as he got the statue it felt like energy was running through him. He could sense dirt all over, and he knew it was his duty to clean. Dipper grabbed the mop and held it over his head, feeling triumphant. He stood there for a few seconds, basking in its glory. When that was done he was ready to clean, and began mopping rapidly. Feeling like there was a fire burning inside him Dipper moved as fast as he could, making sure there wasn't even a molecule of dirt. Satisfied with his work he leaned back, panting with his tongue out. Noticing this Dipper felt... off. A sense of "why is that there" came over him and closing his eyes he simply decided to roll his tongue back in.

Then it came back out.

Dipper frankly wasn't sure to react. Just trying to roll it back in was like trying to move steel. It wouldn't budge no matter what, and Dipper stood there in confusion. Feeling a sense of curiosity the boy touched his unmoving tongue, and his eyes began to widen. His tongue felt like it was a bit more flat, the texture feeling different. Dipper slowly backed away, breathing heavily. Thinking of nothing but calm thoughts he closed his eyes, and his tongue soon retreated back into his mouth. Not sure what to do the boy stood there, occasionally tapping his foot to distract from the silence. As seconds felt like hours he stood there, not exactly sure what was going on. Eventually he realized there was only one thing he could do: work. No new sensations would stop that, as weird as they were. With a smile on his face and determination through his veins Dipper decided he could spend the rest of the day as normal as possible. And indeed it went smoothly. There were no out of place behaviors, no weird quirks, just Dipper going about his day. That was... until Mabel came in to the picture.

As night began to set in Dipper eyed his bed, ready to jump in and sleep. Just as he had the perfect spot, a loud voice.

"Hey Dipper, look!"

Turning behind Dipper saw Mabel, a wide smile on her face and a bright sweater in her hands.

"The newest baby. Cool huh?"

Dipper could not help but feel enticed. Not by the sweater, but by his sister's cheerfulness. Like a warm hug her personality gently held him tight, making him feel welcomed. One thing was certain. Dipper wanted more. Leaning towards the sweater Dipper felt like its scent was calling him. At that moment, he cringed. This type of behavior was exactly what led to the incident, and he didn't want a repeat.

But it was too good to resist.

A step and a sniff closer and Dipper felt like he could feel heaven's grasp. Sniffing all over he loved the scent, and a smirk appeared once an idea came to mind. As Mabel tilted her head in confusion Dipper seized the opportunity and grabbed the sweater by his teeth. Letting out a growl like noise the boy began to motion it towards him, wanting it to himself. The closer it got to him the more he pulled, feeling like he needed this piece of Mabel to himself.

"Dipper what are you-" Mabel began.

However her look turned to horror as soon as she saw the loosening fabric.

"STOP!"

Mabel's cries were futiles, as Dipper clutched tighter and the bottom half of the sweater ripped clean off. The boy fell to the ground, still clutching the wool with his teeth. Getting up Dipper was delighted to capture that part of what to him what his sister, but this evaporated as soon as he saw the tear on her face.

"Mabel I'm so sorry I-"

Before he could even finish Mabel began to speak.

"Dipper, we've been through a lot. And at this point I welcome the weird. Shakes things up. But with this... It's scary. I can't tell who you are, and that's the worst part. I'll see you tomorrow."

Before Dipper could even form a sentence Mabel walked away, immediately going to bed. As he stood there he felt what was possibly the worst he had been. He did this. And that killed him inside. Feeling like he was falling backwards Dipper struggled to walk to bed, feeling like the entire world was falling apart and it was impossible to stand still. He made it to his bed and the guilt began to smother him. Several visions overwhelmed his senses, the scene of his sister crying hurting the most. As Dipper closed his eyes he tried to swat the images away and make it to sleep. Although it took effort he eventually felt relaxed, and drifted into a calm slumber.

The next morning Dipper woke up with a stretch and a yawn, but once again felt something weird from behind. Looking next to him he realized Mabel's bed was empty, which was even stranger. Just as he was about to investigate a sensation from his backside struck hard, and he needed to find the source. Moving his arm to the back Dipper reached down and his eyes widened as he felt something new... and furry. Leaping to the nearest window he could find the boy turned around and saw the shock of a lifetime: right on top of his buttocks was a fluffy brown tail. Dipper could already hear the voice cracks coming as he reacted in pure terror.

"Oh my god what's happening? Should I tell Mabel? Wait Wendy said to meet her maybe I should tell her. Yeah that's a great idea. Ok I tell her. But what about the tail? ...Got it, stuffing it down. That should work."

Preparing for discomfort but future avoidance of stares Dipper attempted to stuff his tail down his pants, but the length proved to be a challenge. Sighing the boy stopped for the moment, but his ears perked up as he heard a squeal. Turning around a look of pure horror appeared as he saw that Mabel was standing in front of him, a wide grin on her face.

"Mabel I-"

Mabel put a finger to Dipper's mouth, her smile failing to disappear.

"Dipper, dipper... I LOVE IT!" yelled Mabel as she wrapped her brother in a tight hug.

Dipper felt himself somewhat lifted up as Mabel tightly embraced him, moving her around to show her affection. A thought soon come to Dipper's mind... if his sister forgot that she was dealing with more than another Waddles he could be seen as almost a pet. A frown entered his face, one set in stone by the annoyance equally from a brown wagging blur from behind.
