Leona Lion is the baby (though not a baby) and is like Elmo, on the show. She is the younger sister of Lionel Lion, and the daughter of Theo and Cleo Lion.
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. She likes preschool TV shows like Little Daisy and Fuzzy Wuzzy Bear. Leona Lion can jump.
