Sofia the First: The Floating Palace

When Sofia helps a young mermaid named Oona, her amulet grants her the surprising ability to become a mermaid and visit an underwater palace. Excited to explore the sea, Sofia meets Oona's family and sees a world that is beautiful but fragile. Cedric, disguised as a seamonster, schemes to steal Oona's enchanted comb to increase his magic, and that plot threatens both kingdoms. With aid from friends and a special guest, Princess Ariel, Sofia sets out to rescue Oona and stop a brewing storm. The story keeps a light, kid-friendly tone while testing Sofia's kindness, quick thinking, and sense of responsibility, and Sofia grows in courage.

Released in 2013 on Disney Junior, Sofia the First: The Floating Palace was directed by Jamie Mitchell and Larry Leichliter, created by Craig Gerber. It features voices from Ariel Winter, Darcy Rose Byrnes, Zach Callison, Jodi Benson, and Jim Cummings.

The Floating Palace premiered as a television special and home market release rather than in theaters, so it does not have a box office total. Disney distributed it via Disney Junior broadcasts, home video, and streaming platforms aimed at family audiences.

The guest appearance by Princess Ariel created a memorable crossover that linked Sofia to classic Disney princess lore, pleasing parents familiar with The Little Mermaid. Visuals like the floating palace and Sofia's mermaid transformation appeared in promotional art and licensed toys, helping keep the series visible across merchandise and preschool programming.

Audience ratings were generally positive, averaging around 7.1/10 from 92 votes, reflecting its family appeal. Reviewers and caregivers praised the warm, accessible storytelling and emphasis on friendship, responsibility, teamwork, and respect for the sea, offering gentle life lessons tailored to preschool viewers and their caregivers.
