Put a tiny piece of green stuff over the ball, let it harden and then I put a little glue on it to really keep it there, then put the helmet on, should be able to articulate fine without popping off easy. For the hose, I used a hand drill to put a piece of paper clip into the hose and mask. There might be a small gap after you glue it together, little green stuff painted black works perfect. Takes a while, but it turns out really nice
