Katuri Season 1 Episode 14 Tortoise Rock

While the little pheasants play a game with small rocks, Duri's rock breaks. Chip goes with her to the riverside to find a new one. When they return to play again, Duri's new rock moves around by itself. In fact, it's alive and it's a tortoise! They return the tortoise back to his home and learn to ask the important question when they collect the rocks: "Are you a rock or a tortoise?"
