Go under the first bridge

You go under the first bridge and see a huge tree trunk uprooted, lying in the dank sludge. You go around it and see it is now a nest, carved into the trunk a living space, a shelter from enemies, a home in wood, a life that's brown, believe in it's strength, semi-permanent greens, aroma of bark, smoothing it with your form and all its rubbings.

1. Can't stay forever, must wander
2. Move in, Location, Location, Location
3. The nests maker objects to your presence
4. You come to lying in warm, dark mud
5. A large shape leaps onto the bridge above with a thump
6. You run down the dry river bed, eating various things that catch your eye
