Have you played Tears of the Kingdom… Then you’ll know all about the Koroks… Depending on the type of player you are, you will either pick a crying Korok or a happy one for a keychain 
( I personally attached rockets to them and yeet them off a cliff…in the game of course, hence the tears and sad expression) 
But if you are sweet and love to see them happy you should get a happy little Korok, once who isn’t traumatised 😂
