This is perfect for fans of Diary of a Wimpy Kid, Mr Gum and Tom Gates. 'Probably the most exciting millisecond in the history of my whole entire life on earth amen was the other day after school when my mum called me into the kitchen.' Barry is auditioning to be in an advert for nit shampoo.

But when it all goes horribly wrong, Barry has a change of heart.

It's time to stand up for all insects and give a bug a hug!

Join Barry in his quest to save the creepy crawlies in this nutty, nitty World Book Day adventure.
