Appearence
Gruff is so far the only known member of the Hobblegrunts. It has a big frill at the back of its neck, clawed wings, sturdy nadder like legs and short arms. It's head is mostly lime green with one nasal horn. It's eyes are completely white like that of the Whispering Death (this might indicate it has bad vision like the latest). It's body is mostly purple spotted with green or blue. It has long teeth protruding from the lower mandible.
