I had this thought one afternoon and decided to expand it into a short story. A short story that is hopefully heartwarming and disturbing at the same, but you'll be the judges of that.
DISCLAIMER: Frozen is owned by Disney. Coraline is owned by Neil Gaiman and Laika.
"Do you want to build a snowman? Or ride our bike around the halls? I think some company is overdue, I've started talking to the pictures on the walls! Hang in there, Joan. It gets a little lonely, all these empty rooms, just watching the hours tick by…"
She was young, no more than nine. She was innocent. She was foolish. Above all, she was loving.
When the doll returned to her, she clipped away the features of her last meal and filled the empty shell with cotton. Soft, like the child's common sense. Pearl grey buttons would do this time, for they matched her hair so well. She sang to herself as she carefully threaded the white strands of yarn into the red braids. Now for the dress. Dark green and a brown bow. Yes, it was wonderful!
Opening her window, she let the new image float off into the starlight. This web would be woven and destroyed in an evening — two, at most. She could feel it.
Knock knock knock-knock knock.
Anna sat up and stared at her bedroom door before scrambling up and running to it. "Yes?" she asked, daring to let her hopes rise. When she opened the door, however, they sank once again. No lost sister waited for her, or even lingered in the hall. All she found was a small white box on the floor. Looking around, she picked it up. "Thank you…?"
There was no answer, but she could feel the presence of something that was certainly not her parents or Elsa. She retreated back into her room, taking the package with her.
It was pleasing to look at, she thought. The sender had carefully tied it up with a lacy black ribbon, and and a card was attached to the bow. To Anna, from an Understanding Friend, it read in neat cursive. Pulling off the ribbon, Anna flung the lid aside and gasped in delight.
Lying on a pillow was herself, in the form of a cloth doll. The dress was the same shade as her favorite one, the white streak of her hair had not been forgotten and the black yarn mouth was curled up in a simple smile. Its eyes were two polished grey buttons, and as Anna looked into them, they seemed to look right into her. "Hello, little me!" she chirped, unable to tear her gaze from the enchanting sight. Grabbing the doll, she ran off towards her sister's room.
"Elsa! Elsa, are you in there?"
"Your sister is in the library." Gerda was coming down the hall, eying her with amusement. "I thought you were too old for dolls, ma'am."
"This one is special, Gerda. It's a little me! Isn't she perfect?"
Gerda's smile faded as Anna held up the doll. "It's...it's very nice, ma'am."
"I knew you'd like it! Will Elsa like it? I have to go see if Elsa will like it! Thank you, Miss Gerda!" Anna dashed away before the old woman could even realize that something was wrong.
"I met a lady in the meads, full beautiful — a faery's child. Her hair was long, her foot was light and her eyes were wild…"
The twelve-year-old and her father stiffened as Anna bounded into the library. "Elsa, come and see this!"
"That's enough for today, Elsa," said the king. "You may go."
Elsa put away the poetry book and curtseyed before leaving, offering a nod and a smile to Anna as she passed. Anna hurried after her, pulling on her sleeve. "Elsa, wait!"
The king pulled her away. "She's studied all day, Anna," he said as they watched her leave. "She's tired. Perhaps another time."
Which means never, Anna thought once he was gone. She flopped on the couch in front of the fireplace, resting her chin on her hand. "This is the library," she said to the doll. "I like it here a lot! It's nice and cozy and I can read all the books I want and watch the clock go back and forth and…"
The little her was not listening. It had found the perfect spot on the floor to set the trap.
"Little me?" Anna asked when she finally noticed that the doll was missing. "Where are you?" She jumped off the couch and poked around the furniture in search of her new toy. At last she spotted it lying next to the rug. "Sorry, did I throw you? I didn't notice." As she stooped to pick it up, she saw a part of the rug turned up. Beneath it, a piece of wood was lighter than the ones around it.
That wasn't here when Gerda lay this out. Anna rolled up the rest of the rug and found herself staring down at a little square door set amongst the boards. A niche in the finely smoothed wood held the handle, next to a gold-lined keyhole. But where's the key? "You wouldn't know, would you?" she asked the doll. Then she realized what she had said and set it down. That was weird.
As the doll touched the floor, a seam came undone as something poked through its side from within. Anna instantly swept it back up, the spell in place once more. "Are you alright, little me?" There was a pointed, black object slipping from the hole, and she carefully pulled it out. "I guess you did know."
In her hand was a long black key, far too large to be from the castle's set. At the handle's end, it formed the shape of a button. There was something elegant about it, elegant and enticing.
Anna held her breath as she slowly stuck the key into the lock and turned it. When she heard the click of gears within, she giggled. A secret passage! Right out of a storybook! "Ready, little me?" She reached for the handle —
Knock, knock, knock. "Princess Anna?" Kai asked, making her jump. "It's tea-time, ma'am."
"I'm coming!" Anna replied as she rolled the rug back down and shoved the key under it. Tucking the doll under her arm, she went to the library door and hurried out. "Can I have some thread when we're done, Kai? And about ten thimbles…?"
For a moment, the library was silent. Then the secret door creaked as something pushed it open. A lump appeared under the cloth and slithered its way to the edge of the rug. A little white mouse crawled into the open, squeaking and sniffing the air. Its black button eyes shined as it looked about.
Tonight, my pet. Tonight.
