In her debut appearance "The Big Sleepover" Lulu joins Hildegard along with Clio at Sofia and Amber's royal slumber party. When Jade and Ruby first meet her they mistake her for a white squirrel. Lulu gets a little offended as well as her owner when Jade admits that Unicorns are her most favorite animals in the world.
Lulu reappears in "Blue Ribbon Bunny", where Hildegard enters her in the Village Faire pet contest where she tightrope walks with her back feet and tail in the air.
- In spite of Sofia's ability to talk to animals, Lulu is the second animal who doesn't speak in the series, Whatnaught was the first.
