Ninjas and "bambu" wood

The first photo is just a training of Cobra ninjas. We have some of them (Storm Shadow V1, V16 and V17, Shadow Strike, Red Ninja, Black Ninja V1, V2, Cobra Slash)
In the second and third photos is a battle of GI JOES ninjas(Storm Shadow V2 , Snake eyes V22 and V23, Quick Kick, Jynx, Agent Jynx, Scarlet and Tiger Claw) x COBRA ninjas.

This is a typical ninja training room of Japan. It was made with some "bambu" wood(it's called bambu in Brazil).
