Create a lifelike animatronic Metridiochoerus, which is a prehistoric giant warthog that is extinct. Based on the fossil skull that has been discovered, we gave the giant warthog model two pairs of fangs protruding to the sides and bending upwards. Its molars are complex and multi-toothed. The appearance is similar to that of an African warthog, covered with dark brown hair. The programming of this Metridiochoerus model is to give him as many head movements as possible, such as ears flapping, mouth open and close with sound, head left to right, which makes the whole animatronic animal very vivid and attractive.
