A "Karnolisz" is the name of an ogre that has sucessfully assimilated to society (for the most part).
These creatures usually accomplish this either by plastic surgury and/or lots and lots of personal hygene products.
The hardest physical feature to overcome is the big green megaphone like ears.
It is typical for even a Karnolisz that has successfully "squeezed" into society, (no pun intended) to still have water sloshing around in their head from growing up in the swamp. It makes them irritable.
-Does Mason look like shrek to you? I wonder if he has a pet donkey?
-Shoosh! He doesn't want people to know he's a Karnolisz! He just wants to be treated like everyone else!
