Leona lion is a female lion
Leona Lion is the show. She is the younger girl of Lionel, and the daughter of Theo and Cleo.
Some irregular forms of words she thinks are regular (e.g. in "A King and His Hawk", she says "hided" when she is referring to hiding a book, and Lionel says the word is "hidden"). In the first two seasons, she is performed by director, co-creator, and writer, Kathryn Mullen (who also acted as puppet captain), while later by Pam Arceiro.
