“What the hell?” Boogerbear rumbled. Leonor realized with a thrill of terror she quickly subdued that the thing looked like a gigantic cross between a turtle and a horned toad. It was heavily armored, with spiky projections around its protective shell, and wore another equally formidable shell on its head like a helmet. Bony protrusions protected small, beady red eyes. Four short legs supported it, at right angles to its body, and a strikingly long, spike-studded tail whipped menacingly behind it as it raised its head and snuffled the air.
