Queen Uniqua is the ruler of a medieval kingdom. She used to be grumpy and obsessed with taking the perfect nap. She became playful and less unhappy after she was turned into a giant by wizards Pablo and Tyrone.
Queen Uniqua wears a bright blue coat edged with gold, a blue skirt with gold trimming at the bottom and covered by a layer of pink silk, and a blue hennin with a pink veil. Underneath her coat and skirt is a pink silk gown.
Uniqua has played Queen Uniqua in one episode of The Backyardigans: "A Giant Problem" from season two.
