I've wanted to see a fanfiction for this for the longest time, but no one wrote it, so I had to take matters into my own hands! Honestly, I'm pretty pleased with how this turned and I think it's a reasonable way for Elsa and Anna to find about their sibling.

Enjoy! :)

"Come on, Elsa!" Anna pleaded. "You need a vacation!"

"I'm sorry, Anna. But as queen, it is my duty to stay with my people," Elsa said firmly, but with a smile.

"You've been working so hard ever since you became queen. You just need a little break!"

"Who will watch the castle while I'm gone?"

"Not me, because I'm going with you wherever it is you're going! Kristoff can watch the kingdom! He's going to have to anyway once we're married soon. Everyone's been teaching him about how to run the country, and trust me, he knows what he's doing."

"Anna…"

"Please, Elsa? We need this. I know it'll help both of us."

"Well…there's some work I've needed done in Africa."

Anna looked confused. "What? What would you possibly need in Africa?"

"There are some herbs I need for some mixtures that only grow there. These mixtures are healing spices and other things that are needed for exports and trade. Perhaps…we can go get them ourselves."

"A jungle expedition?!" Anna squealed.

Elsa laughed warmly. "I suppose so. Alright, Anna, you win. I will prepare our travel arrangements and announce our departure. We must have the best travel crew on hand. After all, the jungle is not safe and no matter how tough you think we are, or how powerful my magic is, we will need protection."

"Whatever you say!" Anna squealed again and tightly hugged her sister before bounding off through the castle halls.

Little did they know what they were about to get themselves into.

"Okay, and you know what to do if we get an import?" Elsa asked Kristoff as she prepared to board the ship.

"Yes, your highness."

"And you know what to do if there's a problem with the townspeople? We've had some arguments going on lately."

"Yes, Elsa, stop worrying. I know what to do, and I have Kai and Gerda with me if anything goes seriously wrong."

"Okay, I believe you. I'm trusting you to lead the country well."

"Elsa, stop torturing him," Anna giggled. "He'll do just fine."

"I'll miss you," Kristoff said as he took Anna into his arms.

"And I'll miss you. Don't worry. We'll be back before you can say 'I hope they're okay.'"

"I hope I don't have to say that."

The engaged couple looked at each other lovingly and shared a good-bye kiss. Kristoff released her from his hold and she boarded the ship after her sister.

The townspeople waved them off as the ship sailed further and further into the distance.

"Anna?" Elsa said. "I must confess I'm a little nervous about traveling. After what happened to Mother and Father."

"Don't worry, Elsa, we'll be fine. Besides, if the waters get rough, you can freeze them!"

Elsa laughed lightly. "I suppose you're right."
