I'm not sure exactly which 'Kazoo Kid story' you specifically mean. There could be many different stories involving a character named Kazoo Kid. It might be a local folktale, or something created within a certain community or family.
As I said before, without more context, it's hard to determine the main plot. But it could be centered around the Kazoo Kid's adventures while using the kazoo.
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.
