Yikyak meat cannot safely be shipped alive - they tend to burst forth from the holds of spaceships mid-flight in a enthusiastically suicidal rampage of hatred. Moreover and unfortunately, freshly harvested Yikyak meat has the general odor and consistency of a hairy sponge soaked in turpentine. Once flash-frozen and aged over the course of 12 weeks, however, the famed Yikyak meat gains the flavor of a sauceless 12-week old Mcdonalds Mcrib. A delicacy always in high demand.
YikYak Herding is a contact sport. Successful herders are treated like royalty by the populace.
