Once upon a time a frog croaked in a very loud and unpleasant voice in Bingle Bog every night. Other creatures living there hated it. One night a nightingale came there and perched on a sumac tree and began to sing melodiously. All creatures living there loved it and cheered her by calling her song divine.
Next night the frog went to the nightingale and said that he was the owner of that tree. He also said that he was known for his splendid baritone and wrote songs for Bog trumpet. The nightingale asked how the frog liked her song. He said that it was not bad but she would merely remain a beginner without his proper training. So she offered herself as his student calling him Mozart in disguise.
Animals came every night to hear nightingale sing and the frog cleverly charged fee for admission and earned a lot. One morning it began to rain. The frog made her practice for six hours. Her voice became hoarse. But at night it revived and she performed well in front of the audience. The frog made the nightingale practice for longer hours and nightingale grew more weak and pale and this affected her voice. So the animals lost interest in her singing and stopped coming .This made the frog angry he told nightingale to puff her lungs according to fashion as she still owed him sixty shillings. The nightingale sang weeping but died due to the burst of a vein.
Now the frog called her stupid as he had tried to teach her but she was tense and nervous and prone to influence. Now the frog again became the undisputed king of Bingle Bog and sang confidently.
