Series 1 showcases the daily life of Dorothy both in and around her house. In addition to recurring Wiggles friends Wags the Dog, Henry the Octopus and Captain Feathersword often popping by for a visit, we meet Fairy Clare and Fairy Larissa, as well as little Fairy Lucia and baby Fairy Maria. Music in Dorothy’s garden is provided by her own Rosy Orchestra. One song is performed in each episode.

Series 2 contains many episodes with a similar formula to Series 1, while others involve Dorothy and a friend leaving her home to perform a task, where they meet a guest star with whom they sing a song. Guests include Leo Sayer as a doctor, Troy Cassar-Daley as a librarian, and Don Spencer as a postman.

Series 3, containing twice the amount of episodes as the previous series, takes quite a departure from the previous two. Although episodes feature many similar plots, as Dorothy is visited by her friends or goes with one to another location, the presentation is very different. Episodes are now narrated by Kendall Goddard, with no songs or dialogue from any of the characters, other than a brief song of Dorothy calling a friend each episode. Dorothy now has a car and plane she uses to get to new locations, which are usually other countries such as France and Italy. Emma Pask takes over as voice of Dorothy, while Brad Carroll now portrays Captain Feathersword. The Fairies are now joined by young Elf Antonio, played by Anthony's son and Lucia and Maria’s younger brother Antonio Field.
