Disney fans love to speculate about their favorite characters and storyline, and “Frozen” is no exception. Here are the top five theories that you might find highly possible.

1. Elsa and Rapunzel are sisters

RadioTimes reported that near the end of “Frozen,” some fans can spot two characters from the film “Tangled.” The fan theory suggests that Elsa and Anna are not really siblings. The true sisters are Elsa and Rapunzel. The stories from both film are estimated to have occurred at the same time, the two princesses are the same age and both are the only Disney princesses who harness magical powers.

2. Kristoff’s coat

Kristoff and his reindeer Sven were best friends in “Frozen.” A Reddit user, superclaude1, stated that the ice harvester always had a coat on, which was made from a reindeer’s pelt, which allegedly belonged to Sven’s mother. The theory states that Scandinavian culture involves Kristoff’s people having much use for animals like reindeer for pulling sleds, as well as for fur and meat. It is possible that the ice harvesters whom Kristoff grew up with killed Sven’s mother, gave the former a pelt coat and gave him the task of taking care of her young offspring, Cinema Blend noted.

3. Elsa and Anna’s parents survived longer than expected

When their parents’ ship capsized, the king and queen actually did not die immediately. USA Today revealed that Chris Buck, director of “Frozen,” said that Elsa and Anna’s parents did not die on a boat, but got washed up ashore on a jungle island.

4. Elsa, Anna and Tarzan are siblings

The royal couple were on the boat for a long time and spent more months on the jungle island after their accident. The queen later delivered a baby boy. Subsequently, the king and queen built a treehouse, expecting to stay on the island for a while, but were devoured by a leopard.

5. The link to “Surf’s Up”

After Elsa and Anna’s parents were killed by a leopard, their baby brother was raised by gorillas. There were also a variety of animals on the jungle island, including surfing penguins.

“So in my little head, Anna and Elsa’s brother is Tarzan – but on the other side of that island are surfing penguins, to tie in a non-Disney movie, ‘Surf’s Up.’ That’s my fun little world.” Buck told MTV News.

There are already plans for “Frozen 2,” so some of these theories may be featured soon.
