I went back to the game today to do some of the things I hadn't. One of which being explore Korok Forest.
I have to admit, I like these twigs. They get it. They have a store and an inn, too, and the inn is free, as Mr. Hero doesn't need to pay to sleep. And buying stuff from their store gets greeted with "Yay, I helped save Hyrule!" How can you not like that?
It then slowly dawned on me that the Koroks, even more than Impa, are probably the people who actually know what's going on. And with 900 of them all over Hyrule, each giving Link a small gift when he finds one... one has to wonder if they're not Hyrule's biggest spy network. They knew Link was awake, they knew he was coming back, and they somehow managed to have one of the most useful magic enhancements in the game ready to go to aid him. All, of course, hidden behind being adorable.
Oh, and Zelda entrusted them with the Master Sword. Can't forget that. They might be cutesy comedy relief... but the Breath of the Wild Koroks are a force to be reckoned with. More than any other people in the entire game, they were ready to put their weight behind destroying Ganon.
