Marshmallow Fluff

Written for Lamia of the Dark's Return of the Daily Weird Prompt Thing

Prompt - Bellatrix is allergic to marshmallows.

There was a reason why Bellatrix didn't eat marshmallows. It didn't matter if they were the squishy squares you roasted over a campfire or jars of pure marshmallow fluff. All marshmallows made her "fluffy and puffy" as she put it.

If someone offered her something with marshmallows in it, her typical reaction was to say, "Get that away from me! I can't eat that. It makes me fluffy and puffy."

"Fluffy and puffy?" Scabior queried. "Just wha do you mean by tha?"

"You know, puffy," she said, acting like he should know what she meant by this.

"You mean they give you gas?"

"No!" Bella exclaimed, her cheeks blushing bright red.

Scabior started to laugh. He was amused by her response, and was now determined to find out what happened when she ate marshmallows.

He started planning how he was going to sneak marshmallows into her food. And the easiest way to do that was to mix them in with something of similar color and texture.

Scabior added a few spoonfuls of marshmallow fluff to a bowl of vanilla ice cream. He knew she couldn't resist vanilla ice cream. It was her favorite. And to make it even more irresistible, he topped it off with some chocolate sauce, chopped nuts and a plump, ripe cherry.

He approached her with the bowl of ice cream while she was sitting on the couch reading a book.

"Would you care for a snack, Bella?" he asked, his voice dripping with false sweetness as he offered her the tainted treat.

She should have known he was up to something. Scabior wasn't usually this nice to her. But the delicious chocolate dribbled over the smooth ice cream looked so tempting.

She licked her lips, her mouth watering at the sight of the snack he'd brought her. She set her book aside on the coffee table and reached for the bowl, eagerly digging in with the spoon Scabior had tucked into the side of the ice cream.

A sly smirk crossed Scabior's face as he watched her eat. He didn't know what would happen to her once she consumed enough of the marshmallow laced treat, but he was going to find out soon enough.

She ate the entire bowl of ice cream, then set the empty bowl on the coffee table when she was finished.

Scabior wondered if something was wrong. Nothing was happening. But then, just as she was reaching for her book to continue reading, fur began to sprout down the length of her arm.

She froze, her hand midway to the book she was reading. Only it wasn't a hand anymore. It was a paw.

"Damn you, Scabior! What have you done to me?" she cried, more fur now growing to cover her face and arms.

Scabior was backing away, a wide grin on his face as he watched a tail poke out from under her dress.

She let out an enraged howl, her voice changing so that her cries resembled that of a raging wildcat, and leapt over the coffee table at him.

Scabior was laughing now as she charged at him. He was just about to turn around and run when Bellatrix suddenly vanished. And in her place a tiny black kitten with grey stripes sat meowing on the floor.

When Bellatrix was a child her cousin Sirius put a curse on her, giving her an allergy that caused her to turn into a kitten for one full hour whenever she ate marshmallows.

It was supposed to be a harmless prank. But Sirius didn't know how to remove the curse. And since no one could find a cure for her condition, Bellatrix was left with an incurable allergy to marshmallows.

Scabior couldn't believe his eyes. There was Bellatrix, now changed into an adorable little kitten.

"Well aren't you lovely," he said, kneeling on the floor in front of her. "You weren't kidding when you said marshmallows made you fluffy. Though I wonder where the puffiness comes in. You don't look very puffy to me."

He decided to see if he could pet her. But as he reached to stroke her back, Bellatrix pinned her ears back and growled at him. Black smoke was trailing from her nostrils, her eyes flashing dangerously as she glared at him.

Her lips curled back, revealing rows of sharp white fangs. She then let out a magnified lion roar, which was so loud it rattled the windows in the house and just about blew Scabior off his feet.

Before the Snatcher had time to react, Bellatrix puffed up her chest, inhaling deeply as her body seemed to swell and grow in size. She exhaled a stream of scorching hot flames right in Scabior's face. Scabior was just barely able to dodge her fiery attack, though not without getting his clothes and the ends of his hair singed.

Moments later Narcissa heard a scream, and turned to see Scabior being chased by a fire breathing kitten.

"I told you not to give her marshmallows," she called out to Scabior as he ran past.

Narcissa sighed and shook her head. It was just another normal day in Malfoy manor. Or at least as normal as things could get when your sister was Bellatrix Lestrange.
