Ariel is a bright, spirited mermaid that thinks and acts for herself, and doesn't do what others tell her what to do. She can be rebellious at times and act rashly to get what she wants, which often lands her in trouble with her father. She doesn't wait for things to happen to her and is proactive about her future. She has a big sense of adventure, always wanting to find something new even if it is dangerous. Her friend, Flounder, is often the voice of reason between the two of them, although she doesn't listen to him anyway.
