Once, a crow was very thirsty. The crow searched for water everywhere.
“Kaa, Kaa, Kaa…”
At last he saw a pot with very little water in it. He put his beak inside. But he could not reach down the water. The crow thought of a plan. He picked some pebbles and dropped then into the pot one by one. The water level rose. The crow drank the water and flew away happily.
