LONDON (AP) — An unused chapter of "Charlie and the Chocolate Factory" has been released — 50 years after Roald Dahl's much-loved children's novel was first published.

The fifth chapter, from a 1961 draft, describes an extra room in the factory called the "Vanilla Fudge Room," which features a "colossal jagged mountain" made of fudge. The draft also featured more children, and showed that Charlie originally went into the factory with his mother, not his grandfather.

The chapter was published in the Guardian newspaper Saturday with the permission of the Roald Dahl Nominee Ltd., an organization that manages his legacy.

The book, which follows young Charlie Bucket's adventures inside Willy Wonka's chocolate factory, has sold millions of copies and inspired several film versions and a West End musical.
