Another plot could be that Athena finds a magical object on the ocean floor. This object gives her the ability to transform into a human for short periods.

Instead of just falling in love with the prince, she discovers a hidden talent among humans like music or art and tries to bring it back to the underwater world.

Also, perhaps Melody finds a magical object that gives her the ability to talk to sea animals in a different way, like she can understand their ancient languages. This could lead her on a quest to find the origin of this magic and how it can be used for good in the ocean world. Another one could be that Melody is cursed by an evil sea witch who wants to take over Atlantica through her. Melody has to break the curse while also protecting her family and kingdom.
