The prolog of a kid story could be about setting the scene. For example, it might describe the magical land where the story takes place, like a forest filled with talking animals and glittering streams. It gives a hint of what's to come in the story.
The prolog is very important in a kid story. It's like the opening act of a show. It gets the kids interested in the story, gives them a taste of what's coming, and helps them start to picture the world of the story in their minds. If the prolog is boring, kids might not be as eager to listen to the rest of the story.
One possible moral could be about the importance of kindness. If the kid in the story shows kindness to the lion kid, it might teach that being good to others, regardless of their appearance or power, can lead to positive outcomes.
I'm not sure of the specific full story without more context. It could be a case of a bully targeting a vulnerable blind child, which is extremely cruel. There might be underlying reasons like the first kid having some behavioural problems or being influenced by a bad environment.
There are two central characters in the 'the kid and the lion kid story'. One is simply a kid, who could be a human child or perhaps a young goat (as 'kid' can have different meanings). The other is the lion kid, which is a young lion. Their relationship and the events that occur between them form the core of the story.
If the big kid in the story learns to be kind and helpful towards the crippled kid, the moral could be about compassion. That we should be empathetic towards those who are less fortunate or different from us.
If it's a story about the big kid helping the crippled kid, the moral could be about kindness and acceptance. We should be kind to those who are different from us.
