Stuck again. I can keep the fireflies with me right up to the point where I have to jump into the first (lowest) cave. I can do this in one jump, without touching the water, but the fireflies always stay behind on rhe other bank. Any ideas??

You only get one jump with the fireflies..and you will need that jump later. You need to build another "bridge" of the wicker thingees so that you can just walk into the cave. I assume you built a walkway for the trip over the first part of the water? With another wicker buoy?

Thanks for your help and for getting back to me so fast - so, I shjould just WALK over the first buoy, since at this point I haven't been to the higher cave so I only have the one buoy, and save my jump for that spot where I get into trouble! This must be the answer and I'm going back to the game now to find out.
