Suzetta is one of Roosevelt Franklin's classmates on Sesame Street, voiced by Loretta Long.

In one "Roosevelt Franklin Elementary School" sketch, Roosevelt finds that Suzetta is upset, because Hard Head Henry Harris called her a canteloupe head. Roosevelt tells her that when you're upset with someone, you should tell them how you feel. He negotiates a peace settlement. (EKA: Episode 0815)
