A rare yet serious disorder which gives the victim the appearance of a small fish such as a bluegill. It also makes it impossible for the victim to digest foods other than M&M's or raisins. Also known as Bluegillitis.
I often wondered why Craig looked like such a bluegill until I found out he had Small Mouth Disorder, or Bluegillitis.

There is little hope for those with Small Mouth Disorder. Poor Craig, they may never find a cure.
