Elsa and Anna's parents are actually Tarzan's parents!
OK, can you keep up with this one? The producers of Frozen started a whole lot of buzz when a fan asked them on Reddit if the Little Mermaid/Frozen/Tangled theory was true. Their response? That the Arrendelle king and queen didn't die in the wreck, but actually escaped to an island, had a son, and were killed by a leopard. That means that Elsa and Anna's parents survived the wreck, lived in the jungle, and had another son (TARZAN!) who was later raised by gorillas. OH.EM.GEE.
