Do you agree with the Frog's inference of the Nightingale's character?Give reason.

No, not at all. I completely disagree on the fact that the frog is a fair judge of the nightingale because he was a very proud, arrogant, obstinate frog with a male chauvinistic approach. Although the nightingale might be wrong in not being too witty to see through the frog's plot but it was none of the frog's business as to who sang what. He was a selfish frog who was worried about his ownership and rule over Bingle Bog and felt insecure at the arrival of the nightingale.
