I see you've found the next step in this adventure. You now find yourself in a forest, where all the animals prance about happily. They offer you a stick of special forest incense and a plate of magical forest brownies. This must be why the animals are so happy!
Well, you can't stay forever, as there is treasure to be won. So, stalk up on forest incense and get going.
