There is a story about The world when it was quite young.
A quick retelling might be something like this:
The world was brown and the sky was blue
a bird flew by and she saw a fox
then the fox suddenly jumped under a rock
and the bird thought that the game was over but not
so for the fox was the slower.
This is probably a lazy writer's version of this story.
Probably one who likes to walk with his dog.
