We awoke from the pleasant ride with the bubble, to find ourself deep in a cave. Presumably dug out by us.
Light was shining in the far end, so we continued to walk further in...
The noise from our steps, and the stones falling in the stream as we walked, echoed in the moist chamber...
As we came further in, the stream was bigger, and there even was some vegatation growing.
We could see the exit of the cave.
