Jambette, Quillson, Rocco, and Kabuki, in my opinion, aren't too pretty. Most will disagree with me on Kabuki, however. Muffy and that one gothic bunny (can't remember her name...) are pretty garish to me as well. And Elise and Monique are equally garish.
But I actually adore Chops and like Gloria, so...
This is a rather old thread already, but I say Gaston, Hazel, Beardo, Prince, Iggly, Zucker, and the list goes on... This is all opinions of course. Alot of people love Zucker, but I think he looks gross to be honest. Maybe if I actually had the choice of eating the food that he was modeled after I would eat it, but Zucker does not represent it well. He looks like a nasty greaseball with freckles, covered in brown sludge, and what not. I see no redeeming qualities in him except his personality type. I love lazies.
