Because of their funny appearance, Shropshire sheep have been made into heroes of various children's series for quite some time. They have amusing adventures as clay figurines.
Shropshire sheep are an old English domesticated breed with a light-coloured coat and a dark-coloured head. These animals are very low-maintenance which is why they're very popular with the farmers. Farmers happily let them graze amongst fruit and conifer crops since they don't chew up the young shoots.
