Oh, I get to ring the gong, but I get no island events. Maybe because I assembled the gong after the time travel. I was hoping a gong event would put a premature end to the long wait for crops, but no dice. I had the gong grant food at least once, where it should have revived the crops, but, alas, none showed up.

That would be a nice addition to VV3 when it comes out.
