Okay I was thinking it might be something to do with fish also, I might just be on that train of thought because Cabin one’s clue had something to do with fish haha but I’ll just type what I was thinking here anyway incase it inspires someone else…
so for the “recent ancients” I was trying to think of some sort of fish/diving creatures that are considered “ancient” but are newer to the game — and then I know there are a few fish that are different sizes now from previous games, so maybe there’s a fish that used to be small/only catchable temporarily throughout the year but they changed it so now it’s a medium size and “permanent” (available all year around)?
this probably isn’t it but idk maybe it will lead us to something
