Figurines portray deities, rulers, and commoners, as well as many types of animals including dogs and deer. Of particular note are the curious childlike Sonrientes (smiling face) figurines and faces. Many of the figurines of this period function as flutes, whistles, and ocarinas. Some animal figurines, interpreted as toys or more likely ritual items, are equipped with wheels, one of the few recorded instances of the application of wheel technology in the pre-Columbian Americas.Diehl and Mandeville, p. 243.
