Holy crap. All this time I had no idea the apple statue things were korok seed locations. I just did the one by Tarrey Town after reading the above posts and realize how many I have passed up along the way. I always just snatch up the apples, lol.
Lol. I was tempted but when I was in Kakariko I put an apple in to get the korok seeds and then I took the apples. Every now and then when I go back to that town I'll take the apples again
