The story is an allegory about a frog and nightingale. The frog's croaking annoyed all the other animals in the forest, but he thought himself the greatest singer. A nightingale's beautiful singing intrigued the frog. He convinced her he could teach her to sing better, but his harsh training methods ended up killing the nightingale. In the end, the frog was once again the only singer in the forest. The story warns about the dangers of arrogance and misguided ambition.
