The pools are the perfect temperature for diving deep, deep, deeper... there is no need for air, and there seems to be no pressure like in water. Suddenly, you crash through the surface! There was no sensation of turning, yet you are upright again.
There is a brief moment of confusion, since the grass looks like grass instead of trees, but it's obvious that you are no longer in the small world. The pools remain behind you, and paths lead north, south, and east. A ravine blocks the way to a large slab of granite to the west.
