First Met: Before Aquamarine
Status: Enemies, Rivals; They sabotaged Cecilia's plans to win her crush's heart.
This is the rivalry between Hailey, Claire and Cecilia. Since before the first film they hated each other. Cecilia presumably always mocked them because she made fun of them in the beginning, calling them babies. But once the mermaid Aquamarnine came into town, Hailey and Claire helped Aqua become the victor in winning Raymond's heart. Cecilia ended up humiliated in the end when trying to expose Aqua's mermaid secret to everyone. The three have always hated each other and are currently enemies.
