On the last day of vacation, Mia finds something special on the beach--a mermaid's shoes!
 
When she puts them on her feet, she knows she has found her true identity. She's really a mermaid! She makes her own mermaid's tail and goes on a quest to find a place to fulfill her destiny. Is it the local aquarium? Maybe the river that runs through the town? In the end, this mermaid finds the perfect place to perch.
