"This small creature is similar to an armadillo with an 'armoured' upper surface of small interlocking 'plates' of tough leathery skin. It feeds exclusively on leaves and small insects and is rarely found outside areas (such as woodland and marshland) where there is a copious supply of such food. Its upper surface armouring is attractively patterned in shades of brown while its underbody is light grey flecked with small green patches. Set in its head, immediately above its eyes, is a large ruby."
