There might be other animals too. Maybe there are fish that the crocodile hunts. So the fish could be considered as characters in a way. They play the role of the prey. And perhaps there are other crocodiles as well. If it's about the old crocodile's family, then its young ones or its mate could also be main characters.
As I don't know the exact story, it could be the crocodile itself as the main character. Maybe there's also a human who has an encounter with the crocodile.
Well, if we think about it, the big crocodile is likely to be a main character. However, there could be other characters too. For example, there might be a small mammal that is constantly in danger of being eaten by the crocodile. Or perhaps there's a wise old turtle that has some sort of relationship with the crocodile, either as a friend or a rival. There could also be a group of monkeys that live near the crocodile's territory and are always on the lookout for the big, dangerous reptile.
The main characters are the enormous crocodile, and also the children it targets, as well as the other animals like the elephant and monkeys who try to stop the crocodile.
The two main characters are the crocodile, which is a reptile known for its long body and sharp teeth, and the giraffe, a tall mammal with a long neck. In the 'Crocodile and Giraffe Love Story', they play the central roles.
The main character is the enormous crocodile. There are also likely other animals like zebras, monkeys or birds which interact with the crocodile in the story.
The main characters are the monkey and the crocodile. The monkey is a lively and intelligent creature. It enjoys its life in the forest. The crocodile, on the other hand, is initially attracted to the monkey's friendly nature but then is influenced by his own bad intentions, which causes conflict between them.
The main characters are the crocodile and the monkey. Simple as that.
Obviously, the crocodile is the main character as the story is centered around it.
I'm not sure exactly without knowing the specific story, but surely there is the friendly crocodile. There might also be other animals like fish, birds, or maybe even some humans if the story involves a human - crocodile interaction.
The moral could be about the danger of greed. Crocodiles are often seen as greedy in stories, always looking for more food or territory.
