What was that noise? For a few seconds, all he could hear was his own heart pounding in his chest Then another sound barged into his ears. It sounded like breathing. Heavy breathing. Suddenly Krrk-Krrk yelped. Arg glanced over his shoulder Krrk-Krrk was standing at the cave mouth He was yelping furiously and spinning in circles That could mean only one thing. A low throaty growl spun Arg back. As his pupils widened, a darker shape separated from the blackness. Two flaming red eyes appeared, bobbing in the darkness high above Arg's head. "Mum?" he squeaked. Arg didn't know what it was. But it definitely wasn't his mum. It sounded big. Very big. The growling got louder. Arg could hear the creature licking its lips. lt sounded very hungry. Arg backed away He didn't turn round. dare That was the first lesson Arg's dad ever taught him about hunting. Don't turn your back on your prey.
