From Nintendo's Role Playing Game Mother 3, the Clayman is main workforce in the Pig King Empire. They are given jobs of manual labor such as digging, lifting and sometimes fighting. They are mass-produced from clay and powered by electricity so they need to be recharged every so often. An inactive clayman can be quickly revived through any strong jolt of electricity.
