The following day, the tortoise went to the same spot and, disguising his voice like the dog’s, he sang the song he had heard the dog sing the day before. A rope dropped from the sky and the tortoise began to climb this rope. At this same time, the dog was just approaching the same spot when he saw the tortoise climbing to the sky. The dog immediately started to sing to his mother. This time, he sang that he was not the one climbing the rope and that his mother should cut the rope. Dog’s mother got a pair of scissors and cut the rope, sending the tortoise crashing to the ground.
This caused tortoise’ shell to break into several pieces. He managed to glue these pieces together, but that was how the tortoise ended up with the rough shell we know today.
