Maybe Martha is the main character and we can look at her personality traits, her goals and desires. Another aspect could be the plot. Is it a linear plot or does it have flashbacks? For example, if it's about Martha's journey, whether it has a clear beginning, middle and end in terms of her experiences.

"Big-bellied Hippo" was a story about a small hippo preparing to go out for a walk in warm weather. In the story, the little hippo saw ducks and fish swimming in the river, so he jumped into the river and drove them away. It also saw the crocodile riding on the little bike, so it snatched it and crushed the bike. It also snatched the lion's drink and popped the boiling balloon. The big-bellied hippo's violent behavior attracted a large swarm of wasps. Would anyone come to save it now? The story also told that the pot-bellied hippopotamus learned to say "please" and "thank you", learned how to be rude and thank others, and learned to treat others politely.
