I would recommend this book to years 5-8. It is a book full of fun. You will be rolling on the floor laughing.
My favourite character has to be lazier than Garfield the cat! His name is Mossop the one eyed cat. He hates catching mice and big fat rats unless they come with free salt on the top of them.
The bit I enjoyed the most was when Michael Morpurgo took you into the story. He made you see the flying pig Pintstine land on Egbert the goat’s head like an OWL out of control.
This is a book with six funny stories in one and I would take it anywhere and everywhere.
