The Zoids Wild are easy-to-assemble model kits that are motorized for amazing motion! Just open the box and snap the armor pieces onto the inner frame, and when you're done putting it together, just turn on the switch! The powerful Ankyrocks stalks forward menacingly with its mouth opening and closing, and its tail swinging back and forth. Its Wild Blast move is operated manually, and it'll swing its tail in a wide arc to dispel its attackers! Requires 1 AAA-size battery, not included.
