Suma had gone for more playthings for her little one, as was her custom. And, as she disappeared through the opening the cub sat for a long time pondering and fighting to keep back the curiosity that was consuming him. As he looked a dark rounded form like a ball of some fluffy material blown by the wind rolled across the patch of light near the doorway. He glided toward it noiselessly, filled with the spirit of adventure. Then he stopped, crouching with tense muscles while his little eyes shone with a new light. Again the strange object came into view on the return trip, and with an agile leap Warruk had pounced on top of it. It wriggled under his feet, and squeaked dolefully and for a moment he was at a loss as to what to do next. Then he cautiously raised one forefoot, bent his head and sniffed at the soft, warm thing and remembered that it was exactly like the rats his mother had brought him, only smaller; but they were always limp and silent while this one struggled and made queer little noises! He raised his other paw for a good look at the creature, his heart pounding wildly with excitement. And the mouse, feeling the pressure relaxing gave one quick wrench and was free. Warruk bounded after it but it slipped nimbly into a crevice in the rotten wood and was gone. Exasperated at being outwitted he clawed and bit furiously at the minute opening into which his captive had escaped, spitting and growling the while. His exertions only tired him so at last he was compelled to stop to rest. It seemed however, that this was destined to be Warruk's unlucky day. Scarcely had he thrown himself down upon the litter of soft chips than another black, rounded form hove into view, precisely where the first had been; but it was of larger size. This time there would be no mincing of matters. He was determined that the new prize should not escape him. With a savage little snarl he rushed at the newcomer and struck it with all the might at his command. A howl of pain escaped him as he tried to lift his paw quite as quickly as it had descended but the awful thing clung to it and it was only after a number of vigorous shakes that he succeeded in dislodging it. In his lack of experience he had planted his paw directly upon a giant rhinoceros beetle with bristling, thorn-like "antlers" one of which had penetrated the skin between the pads. The pain was intense so he held up the injured member and wailed for his mother; he was in trouble and wanted her badly.
