The Hare and the Tortoise.

The story follows on the Race between a Turtle and A Rabbit.
The fable tells us a truth: As conceit makes one lag behind,so modesty helps one make progress.

I was quite familiar with this story.
If make the story into a animation, I think there is greater space for creativity in the process.
The animal models are not a very hard to make. But it is not easy to make that conforming to reality.
