"My powers are so great," Tortoise boasted, "that if you bury me in a grave, I will rise again! Nothing can stop me!"
Leopard didn't believe Tortoise, so he dug a very deep pit into which he threw Tortoise and then buried him. Leopard was sure he would never see Tortoise again.
But Tortoise's friend Rat came and dug a hole so Tortoise escaped.
At first Leopard was surprised to see Tortoise, and then he said, "You're not so great! I can do the same thing."
So Tortoise dug a pit and buried Leopard.
That was the end of Leopard.

Notes: You can read the original story online. In the original story, people come and rescue Leopard in the end, but I decided to let him die there in the ground.
