Shirley Shawn the Unicorn is the most recent Wiggles friend. They're a yellow unicorn with yellow fur, pink and light blue stars all over their body, black eyes, a purple and light pink swirly horn, a purple mane and tail, a red heart-shaped nose, yellow unicorn hooves, yellow mittens and a purple 5-pointed star with a yellow S inside it on their belly. "Scrumptious" is Shirley Shawn's favourite word.
- They were the fifth and final Wiggly Friend to be created, in 2019.
- Shirley Shawn originally did not speak, instead communicating than neighing. Since then, they're sometimes portrayed as being able to speak and other times simply neighs as they originally did.
- They're also the only Wiggly friend to debut after the retirement of Jeff Fatt, Murray Cook and Greg Page and the departure of Sam Moran.
