Bug: If you stand in front of a bug or a fish and press start right after swinging a bottle at it, you can put another item in the bottle's place and turn it into another bottle. When this happens, the erased item cannot be recovered, and the new bottle will retain the limitations of the original item (for example, turning the Claim Check into a bottle will still be unable to be used by Young Link.).

Question: Link was an infant when he was delivered to and raised by the Kokiri, who don't age. When Link becomes a child, they should've realised that he wasn't a Kokiri because he aged. Why didn't they see this?
Answer: Because the Kokiri don't age past a certain age, but they do age up to that age. Link looked roughly the same age as the other Kokiri when his adventure started, which is why they never noticed that he was different.
