While visiting Aunt Darla and Uncle Urchin in Paris, Estelle and Dot are suddenly taken to a mysterious world known as Pocketville where they both discover that they are the wielders of the Ocean's Heart (called Ocean of Friendship in the show) and are in time for the incoming Friendship Ceremony. However, all is not well when evil Princess Eva is interested in kidnapping Dot for revenge and also meets an old face.
- Attack of the 50-Foot Whatever: At the climax of the fanfiction, Eva briefly transforms into a giant version of herself and gets into a rather gargantuan brawl with Ava.

- The Glorious War of Sisterly Rivalry: Ava and Eva even have a literal battle at the climax.
