On one day every year, you can find Harry Potter, Where's Wally, and the Gruffalo in schools across Suffolk.
World Book Day is an annual charity event where children dress up as some of their favourite book characters and receive a voucher for books.
The first event was celebrated in the UK in 1998 - and many Suffolk children have participated.
