And this is totally shocking. Frozen director Chris Buck says Elsa and Anna might possibly have a another sibling. One that they've not met before, and probably won't be meeting anytime soon either. The reason? He's far away in a jungle. You won't guess who it is.

In a recent interview with MTV News, Buck says that Tarzan could be Elsa and Anna's brother.

The reason is that, Elsa and Anna's parents didn't die on their voyage. Instead they were shipwrecked on an uncharted jungle island.

He explains:

I said, "Of course Anna and Elsa's parents didn't die. Yes, there was a shipwreck, but they were at sea a little bit longer than we think they were because the mother was pregnant, and she gave birth on the boat, to a little boy. They get shipwrecked, and somehow they really washed way far away from the Scandinavian waters, and they end up in the jungle. They end up building a tree house and a leopard kills them, so their baby boy is raised by gorillas." 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.

What do you think? Sounds absurd? Or is this whole Disney universe really super connected?
