Before long, we were all transported to the kingdom of Arendelle in the year 1839.

Once outside the WABAC, Penny noticed the townspeople' clothes.

"Why are these guys wearing long sleeves?" she asked. "Don't they know it's summertime?"

"That's what they wear in those days, my dear, despite the change of seasons." I said. "And today is no exception."

"What's so special about today, Mr. Peabody?" asked Sherman.

"Because today, Sherman, is Queen Elsa's coronation day."

Sherman raised an eyebrow. "Who's Elsa?"

"Perhaps I better start at the beginning." I said. "You see, back then, the royal family of Arendelle consisted of King Agnarr and Queen Iduna and their young daughters, Anna and Elsa.

"As children, the girls were incredibly close. But Elsa had a special gift: she had the power to make ice and snow with just a wave of her hands. And Anna admired her for it.

"But their lives would soon change forever, for one night, while playing in a winter wonderland, conjured by Elsa, she accidentally struck Anna on the head, leaving a white streak on her hair.

"The king and queen were already worried about Elsa's growing powers. On horseback, they took the girls to the Valley of Living Rock, where..."

"Wait, wait, wait, wait, wait. Hold on." interrupted Penny. "Living Rock?"

"Well, when I said 'Living Rock,'" I said. "I meant, of course, trolls."

"Trolls, Mr. Peabody?" asked Sherman.

"Yes, Sherman." I said. "But these are not your ordinary trolls. They happen to be healers of magic. Well, at least one of them is.

"While extracting the magic out of Anna, Pabbie, the leader of the trolls, insisted that all of her magical memories should be erased, including those of Elsa's powers, but he did leave the fun.

Before they left, Pabbie warned Elsa about her ever-growing powers, for while there is beauty, there is also great danger, and that she must control it, for fear will be her enemy.

"To take extreme precautions, the castle was closed and the staff was reduced by order of the king, for the safety of Arendelle and Elsa, who moved into her own room for Anna's safety.

"One day, when she saw that it was snowing outside, Anna hurried up to Elsa's door, which she knocked and asked..."

5-Year-Old Anna:
Do you want to build a snowman?
Come on, let's go and play!
I never see you anymore
Come out the door
It's like you've gone away!

We used to be best buddies
And now we're not
I wish you would tell me why!

Do you want to build a snowman?
It doesn't have to be a snowman...

"Go away, Anna." said Elsa from inside her room.

"Okay, bye." sang Anna as she sadly left.

"But Elsa was not truly alone." I went on. "The only people who visited her were her parents, who gave her some gloves."

"These should help." said the king as he put them on her daughter's hands. "See? Conceal it."

"Don't feel it." added Elsa.

"Don't let it show." They said together.

"Four years had passed," I proceeded. "And Anna still longed for companionship."

9-Year-Old Anna:
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...
Tick-tock tick-tock tick-tock tick-tock

"But still, Elsa would not come out." I furtherly went along. "Even as teenagers, they still lived apart from each other.

"One day, the king and queen set out for a two-week voyage. But a storm gave way, and their ship tragically sank.

"The news of their sudden departure spread throughout the kingdom.

"After the funeral, Anna, one of the only two members of the royal family who attended said gathering, slowly walked up to Elsa's door and knocked on it one last time."

15-Year-Old Anna: Elsa?
Please, I know you're in there
People are asking where you've been
They say, "have courage" and I'm trying to
I'm right out here for you,
Just let me in

We only have each other,
It's just you and me
What are we gonna do?

Do you want to build a snowman?

"But Elsa was overcome with grief that she didn't even bother to respond or open the door." I concluded. "So for the next three years, the two sisters lived alone and isolated, and all of Arendelle fell into sadness...until now."

"Wow." said Penny once I finished my story. "That must've been so hard for them."

"It surely was." I said as we walked towards the bridge, which led to the castle. "But, today is sure to promise a bright future for the kingdom, if all goes well, that is."

"You think so, Mr. Peabody?" asked Sherman.

"I know so, Sherman." I replied.
