The Hammerboy is an annoying little purple creature living in the house above the underground cavern. He was probably made by Klogg. He has a big hammer and uses it on Klaymen when he stumbles into a hole in his house, finishing the job and knocking him in. It is unknown if he does it in order to use Klaymen in a sacrifice ritual, to guard Klogg or just because he is a disagreeable bore.
