Here folks are some Preview Pictures for the next Ninjago episode: The Stone Army!
One more thing I really wanted to show off is how this whole "Stone Warrior" idea is supposidly going to run. It seems that these "things" have been awakened due to Great Devourer Venom, and the only thing that can defeat them is the "Gold Ninja: Ninja of Light". This is only speculation, so dont take it seriously :P
UPDATE (Ignore paragraph above this)
After watching the new episode, it seems that there is no Gold Ninja, and that the pictures were merely ones of the First Spinjtzu Master.
