From Master Wu: My father, the First Spinjitzu Master, taught me the ways of Spinjitzu and the wonders of Ninjago. Since I was a boy I have recorded these lessons so that I may teach others. Parts of this book are from journals I kept as a child and young man (yes, I was young once!) and others have been written in as I have learned them. I have also commented on the pages whilst reading this book later on in life . . . To be in possession of The Book of Spinjitzu is to have great responsibility. The information it contains is to be used wisely, and only for good. It is my hope that the reader will let the power of Spinjitzu unlock the true potential within them and become one of Ninjago's great champions.This stunning guidebook is filled with never-before seen illustrations. It's an informative-and funny-look at life as a ninja, as told by the one and only Master Wu.
