Did you get a look at the goblin king from the Hobbit part 1?
Try dividing racial characteristics into Nature and Nuture categories. That should give you all the wiggle room you need to get crazy:
Nature: height, eye shape, skin color, hair color, number of toes...
Nuture: weight, build, tattoos, hair color, skin color, piercing/stretchings, implants...
I did...there's nothing really un-goblin like about being big and fat and (for reasons quite aside from his weight) ridiculous. A better example of cross stereotype would be the Goblin King from Labyrinth. Whatever he is, David Bowie isn't my idea of a goblin--though he does fit quite well my idea of the King of the Fae; and goblins are traditionally some of the Unseelie parts of the Faerie Court. So the King of the Goblins does not necessarily have to be a goblin himself.
On your list-weight and musculature are only minimally an issue of nurture; a tiger will never be as fat as a walrus. The same applies to height, and physical attractiveness, the three characteristics the original poster used as examples. Skin and hair color are also genetically determined.
Body art-tattoos or piercings, weren't what was being asked about.
