With his claws dug deep into the beasts skin he could feel the muscles contract and pulled himself forward, further away from the side of the mouth, as was his plan.
He felt the tremble of the large maw shutting ripple trough the creature's muscles. So Ujauja dug himself deeper, to further get away from the tendrils and teeth.
Completely submerged in the loose sand, climbing down with sharp claws that tore short but deep tears in the monster's skin.
With nothing but exposed skin in front of him and white sand around him all he could do was climb further down until he ran into a vital organ.
Perhaps it was the sensory deprivation that called Ujauja back to reason, maybe he was tired. For now he kept descending. But something of a coherent plan was forming.
