The story the Crow and the Sparrow is a story about Kaakamma the crow that lived in a mudhouse and Gubbamma the sparrow who lived in a brick house.
The lesson that you can get from the story is that you should be grateful for the deeds that someone has given you. If you will be ungrateful, you may suffer a consequence in the end. The crow had a taste of his own medicine when he tried to eat the little sparrows of Gubbamma. Luckily, the wooden toy of her little ones saved their life. With kaakamma's ungratefulness, he was thrown outside and had to spend the whole night out in the cold, getting wet in the rain.
