It's a tale where the frogs, not satisfied with their situation, seek a king but end up getting into trouble as their choices don't turn out well.
The story is basically about the frogs' longing for a king and the unexpected consequences they face when they get what they wanted. It shows how sometimes our desires can lead to unexpected and not-so-great outcomes.
It's a fable where the frogs ask for a king and get ones they don't expect, teaching a lesson about being careful what you wish for.
The moral might be about self - governance. The frogs, by asking for a king, were essentially giving up their own ability to rule themselves. When they got external 'rulers' like the log and the stork, it led to problems. This could imply that we should trust in our own capabilities and not rely too much on outside forces to lead us.
The story of the frogs who wanted a king goes like this: The frogs, lacking a leader, sought one. However, the kings they got weren't what they expected and led to various complications. It's a cautionary tale about being careful what you wish for.
The moral can be seen as the folly of blindly following the crowd. The frogs as a group desired a king without really thinking about the consequences. They just followed the general idea of having a king. And this led to the situation where a predatory stork became their 'ruler', which was a disaster for them.
The primary characters are the frogs. They are unhappy with their state of no king and voice their desire for one. And then there's the stork which is brought into their lives as a result of their wish and becomes a sort of antagonist as it preys on the frogs.
The main characters were the frogs, of course. They were the ones who started the whole situation by asking for a king.
I'm not sure specifically which 'venomous frogs story' by Stephen King you mean. He has a vast body of work, and this might be a relatively unknown or misnamed piece. It could be something from his short story collections that hasn't gained as much mainstream attention.
As I don't know the exact story, it's hard to say. But generally in King's stories, there might be elements like fear and the unknown. The venomous frogs could be a symbol of some hidden danger.
Once rejected, twice desired could mean a situation where someone or something was initially turned down but then later became highly sought after. For example, a job applicant might be rejected at first due to lack of experience. But after gaining more skills and knowledge, the same company desires to hire them. It could also be about a product. A new gadget might be overlooked when first introduced but after improvements and better marketing, it becomes highly desirable.
Maybe the story focuses on how a group of frogs overcomes challenges together or learns important life lessons. It might also involve their interactions with other creatures in their environment.
