SAVES:

These reptiles somewhat resemble a single-horned rhinoceros.
Their head and neck is protected by a bone shield (AC 3) while their skins are very thick -almost plated.
They are herbivorous, but they tend
to be somewhat aggressive. They will trample smaller creatures in a
charge, inflicting 2-16 HP damage.
