Pecopeco

 is a large bird that is commonly found in the desert. Although it cannot fly due to it's large body, its firm legs allow it to run faster than any other land animals. Sometimes Knights will domesticate them and ride them. Nowadays, Pecopeco is popular as mounts for Knights and Crusaders. They live in the desert or forest and will attack in flocks if one of them is threatened.
