It is about a giraffe, a pelican, a monkey and a little boy, who cleans windows really quickly. The author of this book is Roald Dahl. I like it because it is very funny and exiting. I love how the characters act especially The Duke of Hampshire who gives the animals and Billy whatever they want. He has a walking stick that is actually a sword. I recommend this book to everyone. If you like funny books then you should read this book.
