A paddle-limbed monster with a hairless, faceless head came sculling past them, through the warm reeking air. The front of its head was a nightmare of sharp grinding jaws and blunt armored acid spouts. "A tunneler," Mirny said. "It can take us deeper into the Nest—come with me." She launched herself toward it and took a handhold on its furry, segmented back. Afriel followed her, joined by the two immature springtails, who clung to the thing’s hide with their forelimbs. Afriel shuddered at the warm, greasy feel of its rank, damp fur. It continued to scull through the air, its eight fringed paddle feet catching the air like wings.
