>>3264443Drawing obese people is hard because it's outside of the usual skillset. You can either try hard and make him the abomination he is, or just settle for making him chubby (which is cuter anyway). I have spent a lot of time fretting drawing and redrawing Cartman's manboobs so they're big enough, so I understand both sides.
It's fic writers who make older Cartman lose weight who really have no leg to stand on.
