What are the main characters in the Karl King of Ducks story?

I'm sorry, I haven't actually heard of a specific 'Karl King of Ducks' story. It might be a very unique or local tale.

The main characters are the 3 little ducks, of course.

Not having read 'the star ducks story', it's just speculation. Maybe there are star ducks as the central characters. There could also be a villain character, perhaps a fox that wants to catch the star ducks. And there might be a little mouse that befriends the ducks and helps them outwit the fox. The interactions between these characters would then form the plot of the story.

Since I don't know the exact 'star ducks story', I can only guess. There must be the ducks themselves as the main characters. Maybe there could also be a wise old owl who gives the ducks advice.

The 10 little rubber ducks are the main characters. There may be other animals like fish or frogs that they interact with during their adventure, but the focus is on these 10 rubber ducks. They each have their own little story within the overall story as they face different situations and challenges.

Since I don't know the specific 'Star Ducks' short story, I can only guess. The main characters are likely the star ducks themselves. There could also be other animals or characters that interact with the ducks, like a wise old owl who gives them advice or a sly fox that tries to trick them.

The main characters are obviously the four little ducks.

The main characters are the three little ducks, of course.

The main characters are of course the ten little rubber ducks. They are the focus of the story and what the whole plot revolves around.

The main characters are the five little ducks which are the focus of the story as they leave to explore. And the mother duck, who is an important part as she watches her ducks go and waits for them to come back. She represents the loving and patient parent in the story.
