|“Because not all lessons are about fighting. And I misplaced my lesson book.”|
Wu's Lesson Book is an item in which Master Wu wrote lessons he had learned from his many years of experience to teach his students the way of the Ninja and the art of Spinjitzu. At some points in his life, he stopped writing in it for years, but resumed after Garmadon's banishment and while training the Ninja. When he was young, Wu wrote the secrets he learned from the Scroll of Forbidden Spinjitzu, but when he was older and wiser, he placed a seal over it so no one would ever see it.
- This book exists in real life as LEGO Ninjago: The Book of Spinjitzu.
