The ice block on his head provides amazing protection from damage.

One day, a Cave Zombie fell head-first into a glacial stream. It had been a bad day already, so he lay there in the frigid water for a long time contemplating the insignificance of his life. When he finally stood up, he discovered that his head was encased in ice. At least, his life had meaning! He was unique! He was Blockhead Zombie! At least, that's his story and he's sticking to it.
