Zelda: Breath of the Wild - Korok Theory and Origins

The Koroks are returning in Breath of the Wild. I go through their history, origins and a theory on what they might be planning in the game. Thanks to Polygon, IGN for footage. The Koroks were once the Kokiri, the fairy children from Kokiri Forest in Ocarina of Time. However, after the Great Flood, they evolved into the Koroks so they could fly and traverse the great sea. Now the Koroks are returning in Breath of the Wild, what are they up to? I propose a theory, and explain their origins.
