This will be a multi-chapter fic telling the adventures of a klutz babysitter and a regular little princess. By little princess, I mean... well you'll see.

CHAPTER 1: Discovery

Elsa, for once, would not expect her bed sheets to be as stuffy as it is. But it's just that, one morning she found herself absolutely covered in blankets, as if the entire world was drawing big against her. She also felt unusually exposed, that despite the blanket, the air was tickling her skin. Discomfort settling, Elsa got up once and for all.

She began thrashing around the suddenly and impossibly large blanket, that, much to her dismay, seemed endless. Finally freeing herself, she stretched out, her arms spreading out to the farthest it can, except that she felt the wood of her headboard, which she usually didn't.

Weirded out, Elsa looked up to her hands, shock hitting like a train as she found small, child hands.

Wait, what?

Now it hit her fully. The air brushing against her body's skin, the pillows seemingly swallowing her, the bed going out of her proportion, her night gown disheveled in front of her, the room becoming bigger all of a sudden.

It's as if she was an eight-year old kid again.

Except that she was.

Panic settled in as a knock came to her door.

"Elsa?" It was Anna. "Breakfast is ready! And guess what? I helped prepare your favorites!"

Elsa scurried to get off the bed to lock the door, and in the process, she let out a high-pitched squeak of protest.

"Elsa? Are you okay? Do you still have a cold?"

"N-No!" She piped, her voice betraying her. Totally not okay.

"I'm doing fine," Elsa said, deepening her voice in the attempt to cover the childishness.

"Really? Doesn't sound much to me. Open the door, please?"

"No, please... uh..." Elsa rummaged for an answer. "I'm not yet c-clothed!"

Anna, from outside, simply blinked. "I didn't know you sleep unclothed. Well—"

"No!" she yelled in embarrassment. Her volume reduced. "I mean, I was changing my clothes when you knocked."

"Oh, I see," Anna chuckled at her silly assumptions. "Then I'll just wait downstairs, okay?"

"Yes, I'd like that," Elsa sounded as if she was grumbling. Anna shrugged. "She must have woken up on the wrong side of the bed," she thought to herself.

As Anna left, Elsa hurried to her wardrobe, frantically searching for clothes to fit her. And apparently there were none as most of her old clothes were stored to the palace's warehouse. Turns out that sometimes keeping the most unneeded things become useful.

In a state of panic she almost forgot that she could create an ice dress. Except that she needed a base cloth for that. Sculpting sharp ice, she used them to cut her blanket until it became wearable cloth.

The only few benefits of being a royalty is the immediate availability of replacements.

She strapped the cloth around her body and did her little sublime trick and formed a new ice dress truncated just a few inches before her knees, hung to her body by two thin straps.

She then had to get out of Arendelle. Whenever unusual magic — or at least something beyond her ice powers — happened, the trolls were the best advisors. And, considering that it happened a day after she took a medicine from them for her cold, Elsa couldn't find any better logical conclusion. But of course she couldn't show them her current state which might set everyone on panic — both in positive and negative ways. And she just really had the bad habit of not letting anyone know her troubles.

She could literally jump out of the window, but the front court was just below. First choice opted out, she rushed through the secret door that led to Anna's room, which was closer to the stairs. That way, she didn't have to expose herself on the open intersection between her room and her sister's room. She took the spiral staircase in haste, down, down until she finally slipped unnoticed to the gardens.

She was about to approach the front court and blend in with the children until she realized how her ice blue dress stood out from the browns and greens of the commoners. She mentally berated herself for not thinking of taking a cape with her, but it was futile, regardless, because all they had were regal dresses.

Royalty problems, she groaned.

She retreated and walked back, only to bump into something large, burly and hairy.

She gasped upon being discovered.

Goodness, I—

Then she saw Sven standing there, bemused by Elsa's appearance.

"Sven?" she said in her tiny voice, causing the reindeer draw back and blink in confusion, sniffing her afterwards. His grumbles were full of bewilderment, asking how and why it happened. Elsa, being able to catch up, simply shrugged. "I don't know how this happened, either," she timidly said. "I think it has something to do with the troll's potion..." Elsa trailed off as she realized Sven's godsent purpose. She drew a breath in epiphany.

"Can you help me go to the trolls, Sven?"

The reindeer nodded in excitement, immediately kneeling to level himself to Elsa, who, despite such, found difficulty hopping on. Elsa wobbled as Sven stood, gripping tightly on his hair patches.

Ready to go, Sven straightened his body, inhaled a lungful of air, raised his hoofs, set to launch when—

"Sven?"

Startled, the reindeer lost his balance and arched too far back, flinging Elsa off like she failed to defy gravity. He fell sidewards, blocking the tiny girl when Kristoff came to view.

"Sven? There you are boy," Kristoff smiled but Sven tackled the air out of him as he neared. The blonde man fell to the mudpool, Sven becoming the hero of the day by hoofing the mud onto him.

"What the—?!" Kristoff screeched as the mud was intentionally washed over his face. "Sven?! If you don't stop now I swear you'd only have half a carrot!"

Sven signaled with his head and Elsa scampered away with her minuscule feet.

Even as the little girl had gone out of sight, Sven continued to jump around the mudpool, enjoying it until Kristoff gave the ultimatum of no carrots.

Not even Olaf's.

Sven's ears drooped.

Alright, now where? Elsa motioned herself to the rarely visited painting gallery. She entered without much familiarity, the room emitting a refreshing aura, as if it was only her first time being there. She admired each piece that hung on the wall, fixating a few moments on the Arendelle Royal Family — her family's portrait, reminiscing the serene kindness and strength of the parents she badly missed. A pang of bitterness tinged her heart, making her eyes avert to somewhere else. She ended up glancing over Joan of Arc, the lion-hearted woman who was robbed of grace through an accusation of malice — which, she chuckled on, was similar to her experience. She laid down to the seat below Joan, admiring the artistic efforts for accuracy and aesthetics.

As a child, Elsa was less physically active than most, making slumber visit her sooner. The hour of the rat was arriving, and the guilt of wasting Anna's special breakfast was whitewashed by the desire to sleep. She eventually dozed off, only a few seconds away to dreamland...

"Elsa?"

The young lass squealed and knocked to a rather large nose, stood up, various thoughts and excuses spluttering to her mind as she was discovered — yet again.

She looked up to see Olaf, blinking quizzically at her.

"Elsa?" the bewildered snowman repeated as he felt the little girl's hands and shoulders. He gasped dramatically, twigs slinging to his mouth.

"Did I travel back in time?" He turned around, eyeing the paintings with sudden admiration glinting in his eyes.

"Anna told me that this place was very nostalgic to her. It brings back some childhood memories she can't forget — but I didn't know it was a time-warping zone!"

"Olaf—"

"So these paintings have magic powers after all? Like the tales and the rumors say?"

"Olaf please—"

"I wonder if water will suddenly come out from this painting of a voyaging ship and fill this room with water and take me somewhere—"

"Olaf!" Elsa shouted like a child throwing a tantrum, finally getting the babbling snowman to turn to her — still babbling.

"And I never knew you actually went out of your room sometimes to visit these quarters. So Anna wasn't hallucinating at all when she told me that she saw you catching glimpses of her from time to time?"

Elsa froze. So Anna remembered those? "Look, Olaf. First, you did not time travel. Second, it really is me, Elsa. Queen Elsa."

"But that can't be! Why did you suddenly shrink? Did you take some magical youth potion?"

"Yes— No, I mean, I don't... know." Elsa, now at her feet, paced back and forth. "I caught this sort of cold — Anna says it's spring sickness, and since none of the common colds medicine was working on me, they asked the trolls for help." Elsa stopped and turned to Olaf, gesturing to her size. "And when I woke up this morning, it's what I've become."

Olaf simply stared.

"You aren't aiming for eternal youth, are you?"

"Olaf!"

"Well, it's not like a potion can be invented for that again," he laughed and sat beside Elsa.

"Now what are you going to do?"

"I don't know."

"You won't let Anna know?"

"I'm not sure."

"Why?"

Elsa pondered. Yeah, why? Anna wasn't freaked out the least when she discovered her ice powers, and in fact rejoiced in it.

"It was Anna who insisted to have me be checked up by the trolls, even if I told her that magic was unnecessary for such a situation," Elsa explained with her head ducked.

"So you think Anna would feel guilty?"

Elsa meekly nodded back. "Well, even if I tell her that it's not her fault... she's a redhead. Her head's red and sore from being so stubborn. No matter how much you hit her she's still... headstrong." Elsa laughed at her descriptions. Olaf smiled, amused at her portrayal of Anna. A comfortable silence stretched.

"Do you trust her?"

"Of course," Elsa replied instantly.

"Then why don't you tell her?"

"Like I said—"

"Elsa, if you trust Anna, then you should tell her because she'd feel guiltier if you let this last longer."

Elsa returned to contemplation.

"You'll both be fine," Olaf lent a patting hand to the young blonde's shoulders. "You're loving sisters after all."

Elsa's face brightened as her heart warmed from his words. Olaf was the walking life of Elsa's most significant memories and feelings, and she was thankful that he was tangible and did not simply linger in her head, debated by another voice.

The smile remained on her face as she stood and stepped to the door, confident in her trust for her sister. Olaf was there to accompany her anyway.

She tipped her feet to reach the door handle, her newfound confidence shattering as her height snickered to her. She stretched and stretched as if her life depended on it, like she's poor little Alice hoping there was cake somewhere... preferably chocolate cake...

"Need some help?" Olaf offered.

"No," nope, she didn't, because her little fingers had grasped the handle—

"—EAT!" A giant's shout boomed and the door flipped, hurdling Elsa away from the dream chocolate cake... Her mini-air launch played dramatically in slow-mo as her efforts were wasted. She hit Olaf home, squabbling the clueless snowman to a lump of failed claywork.

A red redhead stomped in, footsteps heavily screaming tantrums. "That stinker! She could just tell me if she doesn't like my cooking instead of refusing to eat!" She turned to the painting of a woman.

"Aren't I right, Joan?!" she huffed, nostrils opening wide. But it immediately contracted as her eyes fell upon a piled mass of snow and ice. Soon, Olaf's detached butt was wiggling near the mass.

Anna tiptoed over and epic surprise washed over her face.

"Did I just travel back in time?"

Silence answered, but soon was replaced by a giddy, childish laughter and Anna ran around like a deranged person with her arms extending out on both sides, not quite making an impressive imitation of a bird. What bird runs on their feet while flying anyway?

When Anna finished her lap, she saw an out-of-shape Olaf and a resized Elsa watching her like some circus clown. Her eyes went wide as she realized, for the first time, in many, many years, she was able to see the child Elsa once was... exactly in the same age when things in their sisterhood began to change.

Slowly, Anna approached and knelt in front of Elsa, first taking her hands, fiddling with them affectionately. She poked Elsa's adorable cheeks then pinched them slightly hard. She kept smiling onto a wide-eyed Elsa, until she surprised the little one by heaving her and wagging her around like a precious baby. Elsa squealed in surprised delight as Anna huddled her in a bear hug. "I can't believe I missed out on how cute you are!"

After one last giggle and one last sniff, Anna drew her face back, staring to the curious eyes of her young, older sister.

"Sorry," Anna breathed. "I just really missed you badly. I mean, well, I never got the chance to see my big sister this up close when we were young." Anna laughed humorlessly.

"I must be freaking you out and you probably won't remember any of this anyway..."

And Anna remembered she was time travelling. Her face fell and the sisters mirrored each other's expression.

"Oooooh no! I showed myself up like this! What if I disrupted the timeline? What if everything suddenly changes in the future?" She bit her nails as she put Elsa down. "What if—"

"Anna," Elsa interrupted, voice serious for a child. She fought the urge to facepalm through everything.

Deliberately, Elsa spoke.

"First, you did not time travel. Second, it's me, Elsa. Queen Elsa, your sister who just caught an unusual cold."

Anna wished she really did time travel instead.
