All over the county, students have been dressing up as their most favourite book characters, and come up with some impressive costumes.
From Superman to Peppa Pig, Snow White to Spiderman, Suffolk youngsters have eagerly been sharing their favourite stories with each other.
At Kyson Primary School in Woodbridge, students held a baking competition for a book-themed cake.
Meanwhile, in Ipswich, the Busy Bees at Ipswich Pinewood nursery have thrown themselves into the day with some incredible outfits.
Elsewhere in Ipswich, Ravenswood students rose to the challenge, and there have been rumours that someone even dressed up as Wally - but no-one has been able to spot him yet.
