The swans said, “Dear friend, we, too, do not wish to leave you behind during these difficult times. However, unlike you, we cannot survive for long without food and water. If only you could fly, you could come along with us.”
But the tortoise could not fly.
He continued to plead with the swans to take him along.
Eventually, the swans agreed. They said to the tortoise, “Your jaws are very strong. We have devised a plan, but it is extremely dangerous. You must do exactly as we tell you. If you do not heed our instructions, you will surely perish.”
