David Walliams’ new picture book There’s a Snake in My School will be published in October.

The story follows a girl called Miranda, who “loves to be different”, and so introduces her classmates to her pet Penelope the snake on Bring-your-pet-to-school Day, leading to “uproarious consequences,” according to the publisher.

The new picture book, in collaboration with illustrator Tony Ross, will be available from October 6. It’s already being tipped as one of this Christmas’s bestsellers.

According to publishers HarperCollins Children’s Books the title is “hugely imaginative and fizzing with wit”.

Walliams added: “It was a joy working with Tony Ross on this new picture book, which I hope will amuse my young readers at bedtime.”
