The ending is very sweet. Your story gives a strong message about friendship.
I like the metaphor in your story.
She doesn’t have eyes, so she will have to make new friends without seeing what they look like. She always judges sea creatures on their inside, their personality, not their outside, which she can’t see. That’s why she had really good friends back at her old school that she really missed. She’d rather have a few friends that like her for who she truly is rather than for her looks.
