Who are the main characters in the 'little lost penguin story'?

The main character is surely the little penguin. There might also be other penguins in the colony as supporting characters.

Probably the little penguin itself is a main character. There may also be its parents and other penguins in the colony.

It could be about a penguin that gets separated from its group. Maybe it's a young penguin that strays while learning to hunt or explore. It might face various challenges like finding food and shelter on its own in the harsh Antarctic environment.

The main character is most likely the little lost angel. However, depending on the nature of the story, there could be other important characters. For example, if it's a story set in a human world, there could be a human child who befriends the lost angel. Or there could be a wise old owl in a forest where the angel is lost, which serves as a mentor figure. There could also be a villainous character, such as a demon who wants to corrupt the pure little lost angel.

I'm not sure specifically, but it could be the little lost robot itself as the main character. Maybe there's also an inventor or an owner who is looking for the robot.

The little girl is the central character. Maybe there is a friendly stranger in the story. This person could play an important role in helping the little girl, or at least trying to help her find her way. There could also be some animals that she encounters during her lost time, which could be both helpful or a hindrance.

The main character is the little boy. But depending on the setting of the story, there could be other important characters. For instance, if it's set in a forest, there could be forest animals like a wise old owl or a friendly deer that the boy encounters. These animals could play a role in either helping the boy find his way or leading him further astray. Also, there could be other humans in the story, like a ranger or a hermit who lives in the forest and has some knowledge that can assist the boy in getting back to safety.

The main character is surely the little lost lamb. There might also be the shepherd who is looking for the lamb or the other lambs in the flock that the lost lamb is separated from.

In a story like this, there could be a mentor - like figure for the little lost lord. This character could be someone with knowledge of the area where the lord is lost or someone with special skills. Also, there might be other lords or nobles who are involved in the events that led to the little lord getting lost in the first place, so they could also be considered main characters in the broader context of the story.

The little lost lamb is definitely a main character. It's the focus as it faces the problem of being lost. Another character that could be considered main is the one who rescues or helps the lamb. This could be a shepherd who has a duty to take care of the flock. Or it could be a passer - by who just happens to see the lost lamb and decides to help. Their actions directly affect the outcome for the lamb, so they are important characters in the story too.
