Frozen Theory Confirmed: Tarzan is Anna and Elsa's Long-Lost Brother

Get ready to question reality as you know it because a huge Disney fan theory has just been confirmed to be TRUE: Tarzan is the secret long-lost brother of Anna and Elsa from Frozen.

Speaking to MTV US, Frozen director confirmed that the sibling theory is true. The idea is that, instead of Anna and Elsa's parents dying in a shipwreck as Frozen would have you believe, they actually survived and washed up in a jungle - where they gave birth to baby Tarzan and lived in a tree.

Buck said that the parents, who were pregnant at the time of setting sail, and their "baby boy," washed up on the shore of a jungle and built "a treehouse" before getting "eaten by a leopard."

Which is kind of like… how… Tarzan starts. So, is Tarzan actually Anna and Elsa’s long lost brother? Has your mind completely exploded? Here's what he said to MTV...

"When you're working on a feature, you have a lot of time to think about stuff because it takes four years to make one," said Buck. "I think Jen [Lee] and I were walking to a meeting, and I just start to tell her the entire story."

"I said, 'Of course Anna and Elsa's parents didn't die,'" he added. "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."

"I say, whatever people want to believe, go for it," Buck said. "If you want to tie them all together, then do it. That's the spirit of Disney."

Mind. Blown.
