Articles like this piss me off and just prove that you don't watch what you're writing about properly. It literally shows you that they open up the top/roof of the arena and that they hold these games on a mystery/abandoned island full of overgrowth and wildlife, it was just a bit of random local wildlife flying around and one happened to enter the arena at that time. It's no different from you opening up a window and a bug flies into your home. As for the part where you said the organisers like to middle with the games? OF COURSE THEY DO!!!!! Did you even watch season 1 with the old man that Gi-Hun befriends? What was his name? Oh Il-nam?((Who was also player 001 because that's what his name means)) 🙄🙄🙄
