There might be a fanfiction where Anna arranges a special screening in Arendelle of the events of Frozen for the children.

The idea of good vs. evil is present in both. In Rise of the Guardians, it's the Guardians against Pitch Black. In Frozen, it's Elsa against her own fears which can be seen as an internal evil. In fanfiction, the Guardians could help Elsa face her fears. Jack Frost could use his carefree nature to show Elsa that she doesn't need to be so afraid. And the Frozen characters could help the Guardians in their fight against Pitch by bringing their own unique skills and determination.

The characters' interactions would be really interesting. Elsa, with her calm and powerful demeanor, would likely be cautious around Tarzan and his world. However, as she sees how he is in harmony with nature, she might start to respect him more. Anna, on the other hand, would be very enthusiastic and would try to communicate with the animals right away. Tarzan would be both intrigued and perhaps a bit confused by their foreign ways. He might teach them about jungle survival, while they could teach him about their kingdom and family bonds.
One interesting crossover could be the characters from Frozen interacting with the Guardians in a winter wonderland setting. Maybe Elsa's ice powers could be combined with Jack Frost's in some epic battles against a common enemy. For example, they could fight against Pitch Black together, with Elsa creating ice fortresses and Jack using his frost to make the ground slippery for the enemy.
Well, perhaps in the fanfiction, the magic of the Frozen world somehow gets intertwined with the magic of the jungle in Tarzan's world. For example, Elsa's ice magic could start to affect the climate of the jungle in unexpected ways. Tarzan, being so in tune with the jungle, tries to figure out what's going on. And Anna could get lost in the jungle and Tarzan helps her find her way back while also learning about her world of Arendelle.
Jack Frost watching frozen fanfic might be a very unique and creative concept. It could imply that he is part of a fan community within the fictional world where such fanfic exists. He might be looking for new ideas related to his own domain of cold and ice, or simply enjoying the fictional stories that others have created about frozen - related topics.
Well, he might meet Elsa and be really amazed by her ice powers. Since Percy is used to dealing with all kinds of magic in his own world, he could either help Elsa control her powers better or get into some trouble because of the different nature of the magic in Arendelle. Maybe he'd also team up with Anna to fight against some new threat that emerges in Arendelle.
