A frog and a mouse were very good friends. The frog lived in a pond while the mouse lived in a cave near the pond. Every day, the frog used to come on the land and sit with his friend. One day, the frog decided to play a prank on the mouse. While the mouse was busy talking, the frog tied together the mouse’s foot and his own foot with a string. When the frog leaped into the pond, the mouse cried out in agony. But the frog laughed. After a while, the mouse died. Now, a hawk saw the dead mouse and came to scoop it up. But the frog too was carried off as his foot was still tied with the mouse’s foot. Thus, the frog met with his end as well.
