Sea Fairy Cookie is very quiet, but not shy. She isn't very social, but appreciates company. Her sentences are short, but formal. Although she's quite polite and formal, she often drifts off into her own thoughts, and doesn't complete many sentences unless she is focusing. She spends her spare time looking up at the night sky, longing for her old friend, Moonlight Cookie. Every time she speaks, she seems very distant and nonchalant. She would turn into sea foam if she releases her sword.
