You might wanna try cardboard and aluminum foil, but it might look tacky. Clay...would not work at all. If you hit it on something, it will chip; if you get it wet, it will turn into a glob of poo; plus it would be reeeeeal heavy. Paper mache would probably be your best bet, but you have to put the paper mache around a piece of cardboard er something. If I were you, I would make him make his own damn costume, but thats just me.
