Gills.

I'll let you breathe, but just a sip.
Above and shallow, this lake we dip.

We swim again.
And down we fly.
As weightless heels,
kick weightless skies.

Dusty clouds,
and gleaming planes.

'Cause clouds down here,
will never rain.

Close your eyes and suck in deep.
Down in mud do our feet they seep.

And float in currents.
And make this wish.
We'll stream back to life
on surging fish.
