3D Lego Ninjago Cake

I watched this cartoon a few days before doing this cake. Okto is showing it in the evening, and I happened to catch 1 episode of it. Apparently it is like a star wars spin off, in that the bad dude is the green ninja's father. The green ninja is supposed to be the most powerful one. 
This is actually 5 cakes joined together like lego bricks.
