The creature is grown from the size of a regular Squiggoth up to its full size by the right fungus nutrients and tender loving care that is provided by a Feral Ork Pigdok. During combat the Pigdok that nurtured the creature will sit proudly high atop the swaying howdah on its back, bellowing out orders as the scurrying gun crews load and fire their weapons, wincing as the odd Grot or Ork loses its grip and plummets out of the tower. The Orkeosaurus is capable of carrying up to 12 Orks (whether Boyz, Nobz or Wildboyz) and several units of Gretchin into combat upon its back-mounted deck. These Orks will man any weapons that are installed upon the armoured decking attached to the creature's broad back. These weapons can include twin-linked Big Shootas and Big Gunz.
