Just figured this out after hundreds of gameplay hours
I have no idea if this is news to anyone else but it was news to me: I was approaching a cave with an armored like like at the entrance, I went ahead and flower bomb shot at it from the air while I was gliding down. The usual Keese flying out of the cave animation happened at the same time….and that’s how I found out the “approaching cave†Keese are “realâ€. Like as in, targetable and harvestable and not just some kind of visual effect. I was utterly dumbfounded. Also, score!
