Carla Cannoli is the 'roly-poly' overweight tumbler of "Pearl Bailey High School".
She is seen in the company of A.J. Slick in "The Talented Mr. Dingleberry", deriving pleasure when he slips Steve a drink of Lemon Pledge in order to sabotage his voice before tryouts for the school talent show. But after he forms a ventriloquist act with Roger as his puppet, Carla's leg is broken in a bicycle accident in which she crashed into a flag pole, increasing the chances of Roger and Steve winning.
