Wrong Book Big Book

This is a book about Nicholas Ickle--and he's trying to tell his story. But every time he starts, a new character invades the page. Nicholas tells them all they're in the wrong book, but he's soon surrounded by an elephant, some monsters, a queen and her entourage, a pirate, a puppet and a bunch of rats--they're all trying to get in on his story! Can he tell his tale before the book ends?
