" Peet crouched in the far corner of the den among a pile of animal bones. He lifted a bone the size of a club and whacked at something in the pile. The quill diggle and the family of cave blats wobbled out, clearly in a panic but slowed by the rockroach’s poisonous vapor. The rockroach tossed the quill diggle into its mushy black pucker. "
