/cgl/ - Cosplay & EGL

This seems like the best place to ask this question so here goes.

I'm planning on doing a sex robot costume for halloween.

I'm going to use some air vent ducts for my legs and arms, but what would you guys suggest for the pelvis, torso, and head? I was thinking some cardboard boxes wrapped in aluminum foil, but that seems flimsy and I want this costume to last cause I'm going to use it on several different occasions. Also I'd like to know how I can get the theme song from the video without all the background dialog if anyone can help me out there too, that would be awesome! Also, wondering what you guys would suggest for hands and feet as well.
