The Real Identity of the Witch From Brave: Are you ready for this one? Jon Negroni came up with this brain-boggling theory that not only does every Pixar movie exist in the same world, but they are all connected. The end result: Boo from Monsters, Inc. is actually the witch from Brave.
Frozen Theory, Part 2: According to Chris Buck, director of Frozen, however, they didn't die on that boat. They washed up on the shore of a jungle and the queen later "gave birth to a baby boy" and built "a treehouse" before getting "eaten by a leopard." Sound familiar? That's the beginning of the Disney movie Tarzan. So if this theory is correct, Tarzan is the son of the king and queen of Arendelle and the long-lost brother of Elsa and Anna.
