My Sawsbuck seems to be lagging behind when it comes to changing with the seasons; it’s October and her leaves are still perfectly green! Should I be worried?

Yes, but not for your sawsbuck. As sawsbuck’s form changes with the seasons, any delay in the changing of said seasons—say, global warming—will also delay sawsbuck’s transformation. Therefore, if you happen to live in a region that actually has four seasons (as opposed to a region with naturally consistent weather throughout the year, which locks sawsbuck in one form) and if you’ve noticed that your sawsbuck or wild specimens have yet to change, it’s very likely due to climate, rather than health. 

On that note, seeing as this issue is likely related to climate change, rest assured that the scientific community has actually noticed the same thing you have, and we have already informed—and subsequently gotten ignored by—any legislative body that could take any steps whatsoever towards stabilizing the environment.

Thanks, Unova.
