Elsa, Anna, and Tarzan Are Siblings
If you don’t buy that Elsa, Anna, and Rapunzel are cousins, perhaps this theory about their family tree will be more up your street. This theory suggests that the King and Queen of Arendelle didn’t actually die in a shipwreck, but washed up on an island. From there, the pregnant Queen gave birth to a baby boy — Tarzan — and the couple was ultimately eaten by a leopard (these two really don’t have much luck). Interestingly, Frozen’s co-director has basically confirmed this one.
