Thanks to your hint and my hunch, I've now got 7 treasures. I'm missing the golden egg that you've got and the last treasure that neither of us have got, unless you've got any further. Any hints on the golden egg?
I'm damn sure that those glowing grubs have something to do with the last treasure, but I think I'm suffering from a guess-the-verb problem. I have the moss and the empty trap, but can't work out what to do with them.
