Who are the main characters in the sad story?

Since I don't know the exact'sad gamba story', it's hard to say. But it could be Gamba as the main character, and perhaps there are other characters like Gamba's friends or family members who play important roles in the story.

Another possible main character could be a wise old mermaid. She might have tried to warn the sad mermaid about the consequences of her actions, like falling in love with a human or making a deal with a sea witch. Her warnings, though well - intentioned, might have been ignored by the sad mermaid, leading to her current sad situation.

I'm not sure as the story isn't described here, but it's likely the tree itself is a main character.

Since I don't know the exact 'the sad camel story', I can only guess. Most likely, the main character is the sad camel itself. There might also be a camel herder or other animals in the desert that interact with the sad camel.

The primary character is the sad elephant. Depending on the nature of the story, there might be other supporting characters. If it's a story set in a zoo, the zookeepers could be characters. They might be either trying to help the sad elephant or be the cause of its sadness if they are not taking good care of it.

I'm not sure as the title doesn't give specific details about the characters. But usually in a sad love story, there would be a couple, like a man and a woman in love. Maybe there's a protagonist who is deeply affected by the sad events in the relationship.

The sad prince is the central figure in the story. There could be other characters such as the poor citizens in his kingdom. They are important as they are the ones whose suffering the prince witnesses. Maybe there is also a messenger or a court jester who adds some color to the story and helps to show different aspects of the prince's character through their interactions.

Since I don't know the exact 'Sad Knight Story', it could have the sad knight as the main character of course. There might also be a damsel in distress he is trying to save or a villain who caused his sadness.

The central character is surely the sad frog. However, depending on the nature of the story, there could be other important characters. For instance, if the story is about the frog losing its habitat, there could be humans who are the cause of this destruction as secondary characters. Or if the frog is sad because of a lack of a mate, there could be other frogs in the story that are potential mates but reject the sad frog for some reason. So, while the sad frog is the main focus, other characters can play important roles in the story.

The main character in the 'the sad clown story' is surely the sad clown. However, there could also be some supporting characters. For instance, there might be a young child who befriends the clown and tries to understand his sadness. Or there could be an old mentor figure who has some wisdom to offer the sad clown in dealing with his emotions.
