Title: KittyBill

Summary: Mabill fluff. A nice lighhearted one-shot after that last one. (Geez, that was intense. Did I really write that?) The name of this one gives the rest away. And now, without further ado, my failed attempt at humor.

Shippings: Mabill

She should have known he would have done this. In fact, she should have expected it of him. And yet she was still caught off guard. She never learned.

Dipper and Mabel backed up against the wall, terror written all over their faces. Mabel panicked, hating knowing that her brother didn't know what to do. Everything he had tried so far had failed or backfired. Why were things so hard when it came to Bill?

The demon towered over the twins, a grin over his face. For some odd reason, he preferred to be in his human form, today of all days.

"End of the line, kiddos." He sneered, hands on hips. The words echoed around the room, adding to the severity of the situation.

Mabel just wanted to wipe that obnoxious smirk off his face. So. Dang. Bad. A flash of red and gold caught her eye, and she quickly glanced in it's direction, praying Bill wouldn't notice. He didn't.

The object the girl saw was the journal, resting in the spot it had been flung to before. She breathed a silent sigh of relief. She checked Bill and Dipper, taking note that the two enemies were having a silent stare-down. She nearly smiled at the thought that the demon would stoop so low.

Without warning, she flung herself towards it, earning a shriek of alarm from Dipper, who had seen her move out of the corner of his keen eye. Grabbing the book, she opened the it to a random page, and smiled when she saw the spell written in bold letters on the crusty page. She stood, and pointed at Bill while chanting in Latin.

"Ego vocabo risus intinge!" She cried. For a moment nothing happened. She looked around, searching for some sign of success. But there was none. A slow smile spread across the demons face, and he smirked at the twins.

"Ha! Did you really think you can defeat me? A powerful-" He never finished his sentence. A packet of smile dip, of all things, appeared, and landed right in his open mouth. He closed it, surprised, and consequently swallowed the entire thing whole, plastic wrapper and all.

He coughed, heaving up small amounts of bile. Being the good person she was, Mabel rushed to get a bucket for the sick demon. She placed it under in head just in time as he threw his guts up.

Mabel cringed from the sight, and Bill didn't even murmur his thanks.

"Typical." Dipper muttered under his breath, and Mabel shot him a glare that could curdle all the milk in the world. He raised his arms in submission and turned away.

Bill recovered in record time, and turned back towards them, wiping vomit off his smiling lips.

"Now, where were we?" He inquired slyly, and a little bit embarrassed by that little show.

"Ahh, I believe you were about to kill us." Dipper replied sarcastically. Bill rolled his eyes.

"Right. But now it's lost the whole 'terror' effect, so thanks alot for that." He sneered, equally as sarcastic.

Suddenly, a blinding yellow light erupted from the demon, enveloping him from head to toe. Dipper and Mabel shielded their eyes from the light, avoiding permanent damage. It went for some time, and while it was happening, the paranoid child wondered what was causing this.

Slowly it faded, and the twins blinked away the temporary blindness, clearing their vision. When they could see again, a small, white cat was sitting where Bill had once stood. Dipper raised his eyebrows as Mabel giggled uncontrollably.

Bill meowed angrily, before proceeding to wash his paws. This just made Mabel burst into hysterical laughter. The cats ears, tipped with a golden brick pattern, twitched furiously upon hearing and seeing this.

Mabel fell to the floor, and started to bang her fist on the ground. Dipper pondered as to what caused this, and began to flip through the journal for some kind of explanation. As if sensing what the boy was thinking, Bill meowed an inquiry as he paused on a specific page.

"Perhaps the smile dip reacted with the magic in you, causing you to shift into the form of a cat." He explained, barely containing his laughter.

The demon-turned-cat hissed his disgust, and Dipper smothered a smile. Seeing this, his eyes narrowed into slits and his claws popped out. He growled a warning. Dipper burst into laughter.

"Sorry Bill, but how can we not find this funny!? You're a freaking cat for gods sake!" Bill hissed, and launched himself at the boy's face. He screeched his alarm, and a tried to claw at the attacking demon, attempting to pull him off his face.

Bill's only reaction was to dig his claws in further, drawing blood. Mabel laughed at this whole scene.

"Mabel! Help!" Dipper begged his taller-by-one-millimetre sister, tugging at the demons fur to pull him off.

"Sorry dude. This is way too funny. Although..." She pondered for a moment, before whipping out her camera and pointing it at the fighting pair. "Say cheese." She ordered, and took the picture. "BLACKMAIL!" Mabel cried happily, hands in the air.

Wondering what all the shouting was about, Stan wandered into the room, a frown on his aged face. His eyes widened at the sight he saw, and he paused at the doorway.

"Uh, hi Grunkle Stan." Mabel stated nervously.

"I'm just gonna go..." Was the only reply, before their uncle slowly backed out of the room.

With one last pull, Dipper dislodged the hissing cat-demon from his face.

"Aha!" He cried, triumphant. Then he had a thought. "Hey, you're a demon, right? Can't you just transform back?" The squirming beast paused in thought, and a bright light surrounded him briefly as the changed back into his human form.

He rubbed the back of his head in embarrassment.

"Yeah, okay. I'm gonna go now." And he dissapeared. Dipper and Mabel stared at the spot he had been standing in, possibly traumatized.

"Wow. Wow." The boy stated.

"We just defeated Bill with smile dip." Mabel also remarked, rather surprised. Silence, then the two yelled at the same time.

"Hey, Ford!?"
