My favourite props are cookies to use in place of figurines. You could make the zombie figs green and PC figs some other colour. Any sugar cookie recipe can be used, and you just make stick people of a useable size.
There's a wacky, "twist-on-a-classic" take on Candyland called Run For Your Life, Candyman!
. It strongly suggests using gingerbread men as your 'health' indicator. You put a dollop of frosting on each part of your gingerbread man as it takes damage. When someone finishes damaging a part (arm, leg, torso, etc.) you rip that part out and give it to them to eat.
It's a funny, semi-nostalgic way to spend an evening around Christmas; but expanding the idea a little makes it more broadly applicable. For example, I like the idea of a model of a great big boss creature which you actively disassemble as the players damage it -- LEGO, candy, bread, Tinkertoys, whatever.
