Eventually the entire bladder is full of fluid. Hinka braces himself and then breathes in, apparently sucking the fluid into his lungs. Practiced in the technique, the tcho-tcho gives minimal sign of any discomfort or fear. He leans forward briefly to stabilize his breathing. After a few seconds, he stands up straight and walks forward to Maeriks.
Maeriks sees that now Hinka has a complete bag of fluid over his head and is apparently breathing the fluid in and out of his lungs. The bladder skin of the krekutil that is in front of Hinka's face is now completely transparent and it looks very thin. Hinka's eyes are wide open within. They even seem to have some sort of skin covers on them, almost like goggles made from interior appendages of the interior anatomy of the creature that extend and seal over his eyes.
Hinka nods and smiles to Maeriks. He pantomimes breathing fully, in and out, and then gives a signal for "ok".
With that Hinka walks to the nearby pond, a small body of water fed by a steady tributary. He descends quickly into he pond, completely submerging.
Pumji, still sitting beside Maeriks, looks up at the big Dannein. "See? It is good. Hinka breathes under the water for many minutes. For all minutes. All night? Yes. All day next day? Yes. Still good. Krekutil water is air water. Hinka live in lake if he tries." Pumji nods to see if Maeriks understands.
"Krekutil makes a man like a fish. Makes the lake like the world and the earth. Tcho-tcho or man with krekutil can make any long swim. No need to see the sun or breathe the air of the sky. This is how Hinka get through long tunnels of the Black Temple."
One of the other tcho-tcho bring another krekutil forward. The creature hangs motionless, a blob of a squid-like length with a large loose translucent bladder below and a tighter bulbous bulge above.
Pumji takes the creature from the other tcho-tcho and offers it up to Maeriks. "Will Maeriks try this krekutil now? Go in the pond, under the water, like Hinka? It is good. Maeriks says 'Let's go!". So now, this is what will happen to say, 'Now we go! Swimming into the Black Temple!' Here is the way."
