Frozen Fever: 19th Birthday

Arrival

The story starts in Arendelle's courtyard with Elsa, Kristoff, Sven, and Olaf preparing for Anna's 19th birthday.

"Okay, here we go." Elsa made a little ice statue of Anna on the top of her cake. "Hmm.... so lonely," Elsa muttered to herself. She was deciding what ice statue to make on top of Anna's birthday cake. She flicked her wrist again. "Stiff...." she flicked it again. She gasped as she had unknowingly made a statue of her hugging Anna's frozen body from two months ago. "I can't do that." She gasped as she flicked her wrist, this time forming an ice statue of the two sisters playing. "C'mon Elsa, this is for Anna, you can do this."

"Relax, it looks great!" Kristoff said from behind her. He had been painting the words 'Happy Birthday Anna' on separate pieces of parchment and was hanging them up on a rope. 

"I just want it to be perfect," Elsa said anxiously.

"Speaking of perfect, check this out!" Kristoff gestured proudly at his work as he climbed down the portable ladder. Elsa turned around and stood blank, looking at it for a second before she forced a smile on her face.

"Kristoff, are you sure I can leave you in charge?" Elsa approached Kristoff and wiped the paint off his face.

"Absolutely."

"Cause I don't want anything to happen to this courtyard." As she said this, a high-pitched screeching noise could be heard moving towards them from the sky at a high velocity. A second later, a red, humanoid, manta ray-like alien with two black lightning bolt-like stripes coming down from his shoulders landed on the ground, sending up dust particles around it. After it landed, it transformed into a human teenage boy wearing a green jacket, and green pants.

"What did I miss? Am I late?" He said with a smirk. "Oh, and I'm sorry about the dust." Elsa turned to him and embraced him warmly.

"Ben! This is quite a surprise," Elsa said, releasing him from the hug. "We were just getting ready for Anna's birthday. It's great to see you though. She'll be thrilled."

"That was quite an entrance!" Kristoff exclaimed, impressed.

"Gotta make an entrance," Ben replied with a grin. Elsa was preoccupied with arranging a plate on a nearby table when she looked up, her expression shifting from concentration to shock.

"Olaf, what are you doing?" Elsa exclaimed, her voice laced with disbelief as she caught the snowman red-handed, or rather, red-nosed.

Olaf's mouth was full, but he managed to squeak out, "I'm not eating cake!"

Ben chuckled at the sight. Elsa couldn't help but smile at the absurdity of the situation. "Olaf," she began, her tone gentle. 

"But it's ice cream cake!" Olaf protested, his voice filled with disappointment.

Elsa approached him gently, "And it's for Anna."

"And it's for Anna," Olaf sighed in realization. With a dramatic sigh, he spat out the stolen cake and carefully placed it back on the plate. Ben looked on in disgust while Olaf shrugged innocently. Just then, the palace clock chimed.

"It's time!" Elsa announced, her voice filled with anticipation.

Olaf's eyes widened in confusion, "Time for what?"

Elsa turned to Ben and Kristoff, "Are you two ready for this?"

Kristoff nodded confidently, "We're ready."

Elsa's gaze swept over the courtyard. "Don't let anyone in until we're finished," she instructed. With a swift movement, she raised her hands, and the twin waterfalls froze solid.

"We won't," Ben assured her.

"And don't touch anything!" she added, a hint of warning in her voice.

"We'll just stand here," Ben and Kristoff replied in unison, a shared chuckle passing between them.

"I'm probably gonna walk around," Olaf announced, striking a playful pose before wandering off.

"And keep an eye on that cake," Elsa reminded him as she turned to leave. She closed the heavy wooden doors with a firm click. Kristoff looked at Sven and then used his high pitched 'reindeer voice'.

"She thinks you're an idiot!" Ben smiled at what the two were doing. "Well, clearly, she's wrong!" Kristoff retorted, his voice returning to normal. Before he could continue, he stumbled into a nearby table, narrowly avoiding disaster. "What? It's fine," Kristoff assured Ben, trying to play it off casually.

Olaf, oblivious to the near-miss, was engrossed in trying to decipher the banner Kristoff had hung. "Hah.hyuk. I can't read...or spell...." Olaf chuckled, his attempt at reading the banner ending in adorable frustration. Ben facepalmed, a mixture of amusement and exasperation evident on his face.

A few minutes passed, and Ben found himself reclined on a bench, lost in the drifting clouds. Kristoff, Sven, and Olaf were fast asleep, their rhythmic snores providing an unintentional soundtrack to the peaceful scene. From within the castle, Elsa's gentle song reached him, a sweet melody that carried a hint of melancholy. A soft smile graced Ben's lips as he hummed along silently.

Suddenly, his gaze was drawn to an extraordinary sight. A tiny creature, no larger than the palm of his hand, was skipping towards them with an almost childlike joy. It had beady eyes, no discernible nose, and a mouth that stretched across its entire face. Its chubby body was supported by small, spherical legs that gave it a wobbly, endearing gait. The creature was clearly made of snow, its form glistening in the sunlight. It paused, its beady eyes meeting Ben's, then turned its attention to the cake, a mischievous glint appearing in its nonexistent eyes. Realizing the creature's intentions, Ben sprang into action, shaking Kristoff and Olaf awake.

I think that's for part one now, I'm out of ideas on how it should end. Ciao.
