So way back when I was attending school and exploring my fetishes a bit, I did an overly simplified, toonish version of the Rancor from Return of the Jedi for my own entertainment, more often than not for vore. Thinking about him and seeing him again in VERY old art made me think of trying to flesh him out not as much a 'Rancor', but rather his own Alien species. The head is clearly based on something else from a game I played but can't remember; the style does remind me a bit of Yoshi's Island.

Nonetheless, I do enjoy this guy even though I don't draw him remotely enough, a gluttonous giant of a creature with multiple stomachs in the rotund gut of his. Again, fleshing out his anatomy and background more, but I am open for some suggestions from the audience as to what his species should be called. Hints are much appreciated!
