Round Characters:
* Ariel: The protagonist, Ariel is complex and multi-faceted. She's curious, rebellious, and deeply desires a life beyond the sea. Her emotions are varied and her actions are driven by strong desires.
* Ursula: The villain is also round. She's cunning, manipulative, and driven by a thirst for power. Her motivations are complex, and she's capable of both cruelty and charm.
* Prince Eric: While not as complex as Ariel and Ursula, Eric is still a round character. He's kind, adventurous, and has a romantic streak. He demonstrates genuine emotions and is capable of changing his mind.
Flat Characters:
* King Triton: While a powerful figure, he's more of a stereotypical authority figure who focuses on tradition and doesn't fully understand Ariel's desires.
* Sebastian: The crab is a loyal but somewhat stuffy advisor. He's largely defined by his role and his fear of displeasing the king.
* Scuttle: The seagull is comical and somewhat naive, providing lighthearted humor but lacking depth.
* Flounder: The fish is Ariel's nervous but loyal companion, mainly serving as comic relief.
Important Considerations:
* Flatness is not necessarily a negative trait: Flat characters can be necessary for providing plot elements, comic relief, or representing specific themes.
* Degree of Roundness: Characters can exist on a spectrum between flat and round. Some might be considered more "rounded" than others.
* Perspective: How "round" a character appears can depend on the viewer's perspective and the specific story being told.
Ultimately, the classification of flat or round is subjective and depends on how a character is presented in the story.
