Who.. or what.. is it?
The large "thing" is a puppet from the anime and manga series, Naruto. It's name is Hiruko. It belongs to Sasori of the Akatsuki, former shinobi of the sand village. Hiruko provides shelter and defense for Sasori. Hiruko has a long, sharp blade, which, in the show, injects poison.
The set includes only one minifigure, Sasori. I will explain each of the parts from bottom to top. Starting from the feet, Sasori wears white and "jean" blue shinobi boots. Next, to immitate a robe, I put a simple black skirt, short. The main body is black with white skin toned hands. There is an akatsuki symbol with a red line (part of the clothes), on the front, and just the symbol on the back. UNder the head is a small mask immitating the collar. The head has only one face, a serious brown anime eye. You have 2 options with the top of the head. You can put pink hair (similar to Cole's in Ninjago), or a straw hat. In the comments, please let me know if you would like me to add Sakura and Granny Chiyo too.
Hiruko (The Puppet).
The set starts out with building 4 wheels on the bottom, making it easy to move without tipping over. On top of the base wheels is a simple lego sphere, holo. You can tuck Sasori inside. Making the sides a little longer, and changing the color of the last piece to brown skin tone will create the arms. There is a flat tile in the middle of the body with the printed akatsuki symbol. On the back there is a moving mechanism ending with a ball shooter, which immitates a blade. To bring the scene back to life, I added a ball chain attached to a blade. You can pinch it and shoot the ball chain, but be carefull! The collar is black and attached to the head. A sticker for the eyes and hair. That's the set, I hope you enjoyed!
