It looks like the last verified contact with them has been in 2018. Recently a youtuber went there and tried to get their attention, but couldn’t find them.
Is it possible they’re not even still around? Maybe a disease found its way onto their island and took them out. It could have even been from the last visitor in 2018.
I find it infinitely adorable (not in the condescending way) that you thought about them and want to know if they’re ok. That’s awesome. <3
