A missing chapter from Roald Dahl's Charlie and the Chocolate Factory has been discovered.
The chapter was called The Vanilla Fudge Room, but it was cut by Dahl from the final version of the book.
It featured two extra children, Tommy Troutbeck and Wilbur Rice, who got into trouble for being naughty on the Vanilla Fudge Mountain.
The chapter was found by an author looking in the Roald Dahl archives.

My favourite book is Matilda and I would add a chapter at the end. It would be her diary 10 years later and she would tell you what she wants to be or what she works as!

I would put in another character in one of the Tracy Beaker books. The new character would be Tracy Beaker's evil identical twin called Trina, who would always gets Tracy into trouble.
Katie, Newcastle, England
My favourite book is James and the Giant Peach. I would add a giant bee called Stingy that James meets in the peach.
Justin, Gloucester, England
My favourite book is Gangsta Granny. However I thought he boy could have had a granddad that he found about in the end and then they could have made a sequel about it.

I agree with Ellie from Warminster, Queenie by Jacqueline Wilson needs more characters to go in the hospital ward. Another of my favourite books is Diamond by Jacqueline Wilson and I think the circus could have more characters than just the ones they have now.
Maddie, Essex, England
I think that Harry Potter should have at least a brother or a sister. I don't think it's fair to have to live with the Dursleys all by himself.

I would like to put a new character in David Walliams' book, Ratburger. His name is Archie and he helps Zoe save her rat because he likes rats for pets.
Aidan, Beckenham, England
I would add some more aliens to Charlie and the Great Glass Elevator, because I liked the bits where he fought the Vermicious Knids!
Anthony, Bedford, England
My favorite book is Four Children and It because they have so many adventures, but I think the adventures are too short. I think it would have been better if they went on one adventure where all their wishes came true.
Methusha, Coventry, England
In Little Red Riding Hood, I would add a chapter where the Woodcutter encountered the Wolf.
Layla, Birmingham, England
My favourite book is Matilda by Roald Dahl. I would add another character called Jack Trunchbull who is Miss Trunchbull's son. He is Matilda's enemy and always gets her in trouble. He is six-and-a-half years old. He gets chased away like his mum at the end.
Joshua, Blackburn, England
My favourite book is Demon Dentist by David Walliams. I would add another character named Billy who is Alfie's best friend. Billy also suspects that the dentist is evil.
Rebecca, Washington, England
I will add a chapter where they had a great 1989-themed party in The Boy in the Dress because it will be fun to have Dennis dancing like mad.
Shah, Essex, England
I would add more characters into my favourite book, Queenie by Jacqueline Wilson, because there aren't many patients on Elsie's ward.
