Prompt: GF prompt with babysitter bill-bill and mabel hanging out, just the two of them?
Gotta love fluff. (I wouldn't mind an angsty ask though.)
Demonic Equivalents
Dream demons were mostly nocturnal. Not that they needed sleep, though what Bill called resting could be the demonic equivalent to human sleep, he supposed. He also knew for a fact the more a demon spent out of Hell or the dreamscape the more it mimicked the surrounding creatures in terms of diet, sleep and attitude. It was an old habit, one meant to let the demon blend into its new world and thus, do a better job of screwing things up from the inside. But the whole imitation problem was something he had to be especially careful about; since Bill's current space included two very rambunctious twins. He was a demon after all, and demons had their own way of doing things. He didn't want to get up one morning and ask Stanford for pancakes, no matter how good they were.
Bill had to be very careful he didn't lose his reputation as Gravity Fall's greatest, most horrifying nightmare.
One said twin trotted into their shared bedroom in the attic, and spotted the yellow triangle tucked up in a mess of sweaters, one of Dipper's hats and other assorted paraphernalia Bill had erh, borrowed when he constructed the nest that sat on the bedside table. His body was pale yellow, and his top hat bobbed very slowly.
"Bill! Hey, Bill? Are you up?" Mabel called out happily, using her best (or was it worst?) inside voice. The triangle cracked open his one eye and scanned the room for her, and opened fully upon spotting her. His faded body brightened sharply as he moved into consciousness and floated up out of his nest.
"Shooting Star! I am now." He said mildly, "What can I do for you?" He straightened his floating top hat, tucking his thin black legs under him.
The girl giggled, braces glinting in the sun. "You always sound like a genie when you ask that, you dork." She teased gently. Bill gave her a playful, hurt look and then switched gears.
"I'm way cooler than a genie Stargirl!" Bill twirled his cane round his arm and his bow tie moved out a bit. The demonic equivalents of puffing ones chest out.
"Sure are!" Mabel chirped matter of factly, and Bill's little shape seemed to swell with pride.
"Hey, so, Dipper and Soos are going guy stuff, and Grunkle Stan's running the shop and its Wendy's day off annnnd…uh, I was just…"
Bill watched her fiddle with her sweater sleeves a moment, his eye lidded as he watched in amusement. Mabel released her lower lip she was chewing on, and finally spit it out:
"I was wondering if you wanted to learn how to make a cake!" When he didn't fly into a rage or say no, she rushed on excitedly. "Since you liked that piece we brought you home so much, I can show you how to bake one, and frost it! And we can make fun fetti, or chocolate! Or vanilla and chocolate which is called marble, or carrot cake! Any flavor really!" She added with a wide smile, as if that could hide her apprehension over asking the demon to bake with her.
"I already know how to make a cake, Stargirl." Bill added, hoping he sounded apologetic enough. He really did mean it, which was strange.
"Oh…well, that's okay." Mabel deflated right before his very eye and it was…odd. So odd Cipher paused and floated back a little shock, because wow she looked so tiny and pathetic like that, shoulders slouched in and eyes trained on the floor.
"Nevermind, Bill."
And with her head down like that, he couldn't see the sunlight hitting her braces and making that cool shiny effect.
Bill considered weighed his options for a split second.
"...wait a second. Did you say cake? Oh, no, I have noooo idea how to make that! Doesn't it involve cheese and pencils, and maybe candle wax?" He asked, making a show of looking especially ponderous, hand up to his 'chin' and all. It worked, Mabel shot back up, smile returning.
"No, silly! It's eggs, and flour and—okay, you want to help me?!" she asked eagerly. It didn't even hit Bill to say no.
"Sure. But I call taste tester." Cipher's voice echoed smugly, knowing Mabel would defend his title to the death against her brother and uncle. And those two caved so badly when it came to the only girl in the cabin. (Of course, maybe Bill did too but he was ignoring that for now.) Mabel all but squealed in delight, and it was a rather cute sound, he supposed.
"Deal!" Mabel jumped up happily and grabbed his small hand.
Cipher was tugged down stairs, and he wondered what the demonic equivalent for a stomach ache was.
Because as much as he loved human food…Mabel was an unconventional cook.
