Dorothy the Dinosaur is one of the Wiggly Friends. She is a "rosasaur" (a dinosaur who eats roses), coloured green with bright yellow spots. She is usually seen wearing a white, floppy hat with a red rose in it, as well as white gloves. Dorothy loves singing, dancing, eating roses and making rosy tea, and she lives in a pink and purple house with a large rose garden in her backyard.

- Dorothy is one of the most popular Wiggles characters, to the extent where she was given her own live tours and even her own TV series from 2007-2011.
- She was the first Wiggles character to be created, being introduced in 1991 and first appearing in her self-titled song.
- Murray Cook was inspired to create her because many of the kids he was teaching in his preschool class were interested in dinosaurs.
- The song Dorothy's Birthday Party reveals the date of her birthday as November 3.
- In An Irish Dinosaur Tale, it is revealed that she was born in Ireland, making her the second character in the franchise confirmed to have a non-Australian family background (after Jeff), and the first (and to date only) Wiggly Friend to have international heritage.
- According to Yummy Yummy, her favorite color is pink.
- As seen in her bedroom in many scenes and promo pictures of her TV series and others, she loves to sleep with teddy bears.
- Her appearances in the Stephen Squirrelsky and Friends' Movie Spoof Travels are The Forest Book 2, Nikki's Adventures of Sing Along Songs Episode 10, Madagascar, Sleeping Beauty, Aurorastasia, Despicable Me (Justin Quintanilla's Style), and We're Back!: A Jungle Animal's Story and will even be in more movie spoof travels.
