Little Freddie Whitemouse, of No.16, Skirting Board West, simply hates being a mouse. Mice are terribly small, frightened of everything, and aren't allowed to have any fun at all. Instead, he longs to be a fierce tiger, king of the jungle floor; or someone's treasured dog, able to run and play all day. So when a sorcerer toad hears Freddie's pleas and offers his assistance, there is really little else Freddie could ask for. So as not to make any rash decisions, Freddie agrees to spend a week as each animal. But what will he discover on his amazing adventure? And will he ever want to be just a plain old mouse again?
