Chapter summary: Immortal fraternal twins, Rebecca and Henry, want to build a snowman and there's only one person that can give them that... Their older immortal 19 year old adopted sister Elizabeth...

*They get caught playing!

Chapter I: Do you wanna build a snowman?

It was 3:35 am in the kingdom of Arendelle. All the citizens residing there were asleep on this calm, starry, December night. The royal family was sound asleep in their palace also. Except for one child, he's up and about and desperate to play.

"Psst! Rebecca!" The little boy whispered to his sleeping twin. No response came from her. He climbed up on Rebecca's watery blue bed and shook her up. "Henry..." She moaned, still half-asleep, "Go back to sleep." She added.

Henry rested his entire body on Rebecca. "Beckie, I just can't. The sky's awake. Now I'm awake. So we have to play!" Beckie pushed him off her, "Go play by yourself!" Henry landed with a soft thud on the ground. He thought up of something to get his sister out of bed. His eyes flashed with an idea beaming through.

He climbed up Rebecca's bed again, whispering mischievously in her ear, "Do you wanna build a snowman?" Rebecca opened both of her eyes, grinning. "Let's wake up Elizabeth." Henry and Rebecca ran out of their bedroom straight to, their older adopted sister, Elizabeth's (they have no relation with her) room.

They silently opened the door to the indigo blue room Elize was behind. They saw their 'sister' sleep peacefully on her bed until she stirred. Elizabeth yawned, stretching her arms out. Her eyes were half-lidded, she didn't notice the twins were standing out her door.

She attempted to go back to sleep until she was startled by Rebecca and Henry jumping on her. "What the-Henry! Rebecca! What are you-?" Her whisper had a clear tone of agitation. What do her adopted siblings even want? "We wanna play with you! Please?" They interrupted her.

"No. Go back to bed." She scowled at them, tucking herself back under her toasty covers even though the cold never disturbed her.

Henry pulled off Elizabeth's covers. Beckie smirked, she murmured in her 'sister's' ear, "Do you wanna build a snowman?" Elizabeth didn't hesitate on getting up. Why would she deny that specific request from her recently adopted siblings?

The trio ran quietly through the halls to the throne room. Elizabeth shut the door immediately after the entered. "Do the magic! Do the magic!" The twins happily squealed in unison.

Elizabeth waved her hands in a circle motion, a glowing snowball formed over. "Ready?" She asked, smiling. The twins nodded eagerly. They jumped around trying to catch falling snowflakes.

"Watch this." Elize requested the twins to look down. One tap of her left foot made ice form across the floor. Henry immediately slid across the icy floors, heading straight for the snow. Rebecca grinned at Elize before joining her twin in the fun.

Elizabeth rolled the bottom layer of the snowman while Rebecca worked on the second layer and Henry did the top. "What should we name him?" Beckie asked as Henry placed the carrot nose on, Elizabeth suggested "How about Olimar?" The twins nodded to the name. "Olimar it is then." She confirmed, making 'Olimar' the snowman's official name.

"C'mon Elize, let's skate with Olimar!" Henry grabbed Olimar by his stick arms, Elizabeth stood back-to-back with the snowman. Using her powers, she propelled Olimar, herself, and Henry across the ice. Rebecca didn't want to skate, instead, she wanted to fly with them as they skated. She willed her white transparent wings to sprout out from her back.

She caught up with the skaters in no time flat. The blue fairy dust coming off of her wings made the floors sparkle.

The fun was about to be short lived though.

Henry and Beckie stood atop a snow hill, Elize conjured up a ramp for them to leap off of into a soft snow bed. "It's ready." She confirmed, the twins, not wasting any time, got ready to slide down. Rebecca laid flat on her belly, while Henry was sliding backwards.

"Wheeeeeeeee!" The twins leaped off the ramp into the snowy bed that Elizabeth made for a soft landing, the throne room doors opened abruptly, startling the playing teen.

"What's going on in here?" It was the Queen and their adoptive mother. "I-uh... Um-w-well.. W-We..." Elize stuttered, trying to find a good excuse for what they were doing at now 4:35 in the morning. The twins, popping their heads out, gasped when Elsa stood there tapping her foot, silently demanding an explanation. Busted... They thought to themselves.

Rebecca and Henry tried to sneak away but didn't get very far when Elsa blocked them away from the doors with an ice wall she created. "I will ask you three one more time, what on Earth is going on in here?" She repeated, her eyes were icy pits, and her expression was clearly unreadable. Maybe it's from agitation. "W-We were p-p-playing...?" Elizabeth came clean.

"All of you, go to bed this instant. I will deal with you later on." The Queen commanded, Elizabeth and the twins departed without a hitch.

They should've stayed in bed.
