Official LEGO.com Description
Sharpen your ninja skills at the Airjitzu Battle Grounds!
Join Airjitzu Lloyd and Airjitzu Nya in the practice arena to help them train for their battle against Master Yang, the original Airjitzu master. Choose from a variety of cool training weapons and try out new moves on the Ghost Students. Dodge the obstacles and then detach the Airjitzu launchers, pull the rip cord and send a ninja hero spinning into an aerial battle against Master Yang. The harder you pull, the faster they will spin!
- Includes 5 minifigures: Airjitzu Lloyd and Airjitzu Nya, Master Yang, Ghost Student Chris and Ghost Student Martin.
- The Airjitzu Battle Grounds features a main entrance, 2 side buildings and 2 built-in Airjitzu launchers (with golden and blue propellers) and an assortment of ninja weapons for additional Airjitzu training.
- Open the large entrance doors and activate the collapsing stairs function to topple enemy invaders.
- Place a ninja minifigure on the roof of either side building and open it to send them flying.
