It has a purple couch and a big rug, full of bright, almost nauseatingly bright pastel colors. Also, a nice fireplace and some more modern furniture on one side.
The trees are very green, thick, mostly deciduous, but some pine trees. A little path leads through them. On the ground, near the trees, are many bushes, ferns, and wildflowers. It's very bright outside, but a little dark inside the forest, with the light filtering through the leaves.
It's fairly narrow, but somewhat easy to climb.
It's a pretty stream that is about 5 feet or so in width and continues on one side. There are a few rocks, but mostly just pebbles. The water is brisk, but not rushing, clear and there a few little fish in it.
It is a plastic-ish mug made for hiking, maybe for carrying water or even coffee.
It is small and gold with old-fashioned gilding. It could possibly unlock something smallish like a cabinet or a chest.
