Ms. Turpentine

Ms. Turpentine is a representative of the Grouchenheim Museum on Filth Avenue. She appears in Episode 2657 of Sesame Street.

She arrives on the street, having gotten word of a budding Grouch artist in the area. It turns out to be baby Gabi, who has made a simple, crayon, line drawing that Oscar considers the grouchiest piece of art he's ever seen. Ms. Turpentine concurs and offers Maria several cans of mud and bags of trash for it. Maria refuses to part with it and Ms. Turpentine leaves to scout more talent from the local day care center.
