Kuuku and I: The Afternoon Adventures of Ninjabros (Paperback) (ISBN-13: 9789988342241)

In a world full of humongous slimy monsters, happiness bandits, disagreeable cats, and homework, two brothers are here to protect you. They are best friends. They have cool costumes. They are simply too awesome. They are the ... NINJABROS! With the Ninjabros around, all cupboards are less scary. All bad guys are seriously scared. Disagreeable cats are still ... disagreeable because you know, cats ... and homework, we will get to that later. But you better call them in the afternoon before nightfall because their mom does not play with their bedtime. So, who are the Ninjabros? Put on your cape and let's go find out!
