"Stacks" is a young girl who resides in the Herkleston Public Library, outside The Creek. She is a bookworm who spends most of her free time reading in a hideout behind the bookshelves of the Library and doing other kids' book reports in trade of candy and other things. She does not like doing this as "Nobody respects books". She is good friends with Kelsey because of their love of books, and will often talk about books with her whenever she can.
Stacks is seen long, black hair and a headlight that has a blue strap with a red zigzag pattern. She wears a light blue T-shirt, red-orange shorts, pink leggings and yellow shoes.
She seems to be a book worm since she is obsessed with books. She reads and writes book reports for people and will want to talk about books at any time, especially with Kelsey since no one else has respect for books. Outside of that, she seems to be a good and loyal person.
