Who are the characters in 'the stupid boy story'?

The moral could be to think before you act. In the case of the boy trying to catch the fish, if he had thought about how fish move and what he needed to catch them, he wouldn't have made such a silly attempt.

Sure. There was a stupid boy who once tried to catch a fish with his bare hands in a pond. He saw the fish swimming close to the shore and thought it would be easy. But as soon as he put his hands in the water, the fish swam away quickly. He ended up getting all wet and muddy, but still without a fish.

There must be the naughty boy himself. And probably his parents or guardians who have to deal with his naughtiness.

The main character is the boy in the 'tickle boy story'. There could be a mischievous cousin who loves to tickle the boy at family gatherings. And perhaps there is an old wise neighbor who has some interesting stories about tickling from his own childhood and gives advice to the boy about how to handle being tickled. Also, there might be a schoolmate who discovers the boy's ticklishness and it becomes a running joke between them.

Since I don't know the exact 'chocolate boy story', it's hard to say. But surely there would be the chocolate boy himself. There might also be his family members, like his parents or siblings who could play important roles in the story.

The main characters in the gingerbread boy story include the gingerbread boy himself, who is the central figure. Then there are the old man and the old woman who made the gingerbread boy. There are also various animals such as cows, horses, and a sly fox. The old man and woman set the story in motion by creating the gingerbread boy. The animals try to catch the gingerbread boy as he runs away, and the fox ultimately outwits the gingerbread boy.
