PUPILS, staff and even the school dog dressed up in Princes Risborough to celebrate World Book Day.
Princes Risborough School in Merton Road held the celebrations on Friday and saw Alfie the school dog dress up at Nana from Peter Pan.
There were prizes for the best costume for pupils in each year group.
The learning support department won the prize for the best department costumes as they all dressed up as characters from Mary Poppins.
The headteacher, Pete Rowe, was dressed as The Demon Headmaster, which is a series of books by Gillian Cross.
Head of the learning resources centre, Sue Gough, said: "As always we dressed up like mad. There was a great atmosphere in the school.
"It is a really good day. It is not a primary- it is a secondary school and we are getting kids talking about books, without even realising."
There was silent reading across the school, a big quiz, and £1 book tokens were handed out.
