Well, one thing that could happen is a grand celebration in Arendelle. All the people would come out to see their beloved princess Anna marry Kristoff. There would be ice sculptures everywhere as a nod to Elsa's powers, and the fjords would be filled with the sounds of music and laughter. The ceremony could be held in the castle courtyard, with Elsa using her magic to create a beautiful ice arch for them to stand under as they exchange vows.
Perhaps in the fanfiction, there could be some drama. Maybe an old enemy of Arendelle tries to disrupt the wedding. But Kristoff, being the brave man he is, would fight them off to protect Anna and their special day. And Anna, with her kind heart, would find a way to forgive the enemy and turn them into an ally. Then the wedding would continue with even more joy and celebration.
One possibility in fanfiction is that they start a family right away. Kristoff would be a loving and protective father, teaching their children about the ways of the forest and ice. Anna would pass on her knowledge of the kingdom and how to rule with kindness. Their home would be a place full of love and laughter, with Sven often coming around to visit.
In this fanfiction, the baby might be the key to uniting all the different tribes around Arendelle. Since Anna and Kristoff are from different backgrounds, their baby could symbolize a new era of peace and unity. For example, the Northuldra might see the baby as a sign of hope and start to work more closely with Arendelle.
A special element could be a magical dress for Anna. Instead of a normal wedding dress, it could be made with the help of Elsa's magic. It might have a pattern that looks like snowflakes that sparkle in the sunlight. And for Kristoff, his suit could be made of a special fabric that is warm yet looks very regal, like something from a far - off enchanted land.
One idea could be that their baby has a special power related to ice like Anna and Elsa. Maybe the baby can create beautiful ice sculptures at a very young age. This would add a new element to the Frozen world and also show how the family's powers are passed down.
There probably is. The Frozen fandom is quite large and diverse, so it's not surprising that there could be a fanfiction where Kristoff and Anna are pregnant. It could be an interesting read as it might explore how their relationship evolves with the new addition to their family on the way. Maybe it would also show how their friends in Arendelle react to the news.
One possible plot could be that Anna discovers she's pregnant and she and Kristoff are overjoyed. But then they face challenges like how to keep Anna safe during her pregnancy in the sometimes - dangerous world of Arendelle. They might also worry about how to raise the child with all the responsibilities of ruling the kingdom.
Anna and Kristoff's wedding was a grand affair. The whole of Arendelle was decorated with ice sculptures and flowers. Anna looked stunning in her white dress, with a tiara on her head. Kristoff was dashing in his suit. As they exchanged vows, there was not a dry eye in the crowd. Sven was there too, with a little flower crown on his antlers. After the ceremony, they had a huge feast and danced the night away, their love finally sealed in marriage.
You can try fanfiction websites like Archive of Our Own. There are often many different fanfictions about various characters and scenarios from Frozen, including those about Anna, Kristoff and their baby.
One great fanfiction could be where Anna and Kristoff's baby has a special connection to the magic of Arendelle. Maybe the baby can communicate with the spirits of the forest like Elsa. Another story might focus on the challenges of raising a baby in a kingdom with so much history and responsibility.
One possible scenario could be that they share a kiss after a dangerous adventure. Maybe they were facing a powerful snow monster and Kristoff saved Anna. In the heat of the moment, filled with relief and newfound admiration, they kiss. Another could be during a celebration in Arendelle. After a successful harvest or a new alliance, the joy in the air leads to a spontaneous kiss between them.
