This movie includes the following tropes:
- Big-Lipped Alligator Moment: Several, but mostly the scene with the locusts.
- Bittersweet Ending: Florence loses her means to go back to Flower Land and can't survive in the human world, so she dissolves into morning dew. But Michael heeds her Last Request, convinces his music professor to give him a second chance and becomes a great musician.
- The Cameo: Hello Kitty, My Melody, the Little Twin Stars, and Tuxedo Sam are among the Sanrio characters to make an appearance in the above mentioned scene. Hello Kitty even gets rid of the insects by blowing bubbles that trap them in pairs and then pop.
- "I Am" Song: "My Name is Florence" essentially the only song that is not a classical tune in this film.
- Our Fairies Are Different: Florence and her fairy pals in Flower Land are your stereotypical pretty, sweet-natured little people. Interestingly, they do not have wings and instead just float around to fly like ghosts.
