Insights

Released in 2015 as a Dorling Kindersley Ninjago book, LEGO Ninjago Secret World of the Ninja includes an exclusive Sensei Wu variant that underpins collector interest, and its broad retail distribution and many alternate Wu releases have kept post-retirement upside modest.

Book Facts

The exclusive Sensei Wu minifigure was produced only for this DK book release and not included in standard Ninjago sets.
The book documents early Ninjago narrative arcs, providing character, vehicle, and location descriptions through Tournament of Elements.
All LEGO elements are limited to the single minifigure; no additional bricks or model components form part of the package.
The publication follows the DK format of combining franchise lore with set photography and visual guides.

Jays Brick Blog

“For LEGO Ninjago fans, one of the biggest draws of the book is the exclusive Sensei Wu minifigure which you can get a really good look of in the plastic window embedded into the cover. We’ll take a closer look at Sensei Wu in just a moment. Like most character encyclopedias... More and supplementary books published by DK, you will most likely only appreciate the Secret World of the Ninja if you’re a fan of Ninjago.”
