Rhonkers are bulky quadrupeds with hooved feet and a long, dinosauroid tail which ends in a spiked blade. They are pachiderm-like, with tough skin covering their backs and tails. Like the Yautja Hounds, they also have several fleshy protusions on the anterior part of their backs, which are used both for hearing and heat-dissipation. These structures are homologous to the Yautja's so-called "dreadlocks".
