A roc makes its nest in a tree, while a mouse nests underneath the tree. Every day the roc defecates from the sky, and the feces fall on the mouse's nest. Helpless, the mouse tells the elephant, who ignores the mouse. Later, the roc’s feces kill the mouse’s babies, making the mouse so angry that she climbs into the elephant's nostrils and attacks the elephant's brain. The elephant is in such pain that he runs up and down, knocking down the tree with the roc’s nest. Seeing all this, the mouse wisely says later: "Powerful ones who do not know how to balance, please watch the roc's nest; those who do not listen to the commoners, please look at the corpse of the elephant; the weak ones who cannot bear no more, please see the deeds of the mouse.”
