Mr Koochi is a mouse on a mission. He builds himself a house and grows his own food. ‘Clever me!’ he thinks. All he needs now is a wife. He decides that a princess wife would suit him very well … but after promising he will never abandon her, he finds that she is plump and plain – not exactly the princess he dreamt about. Maybe he isn’t so clever after all. And yet she turns out to be clever and kind – but has his discovery come too late? Mr Koochi has to learn a hard lesson about kindness to win his princess back.
