Pixies are small little fairy tale creatures that are found in woods and forests.
In "Wrath of the Librarian", Muriel touch the book and hardly slide her finger on a page and got an odd paper cut and turned into a Pixie.
The Pixie has blue skin, a long petal/leaf like dress with a pink flower crown on her head with branches coming out of it.
The Pixie is a hyperactive person that likes to fly and takes pride when she tricks the Prickley Pirate and dodges his attacks. She likes flying and talking about pixies.
