Sylvia Marpole is the college head librarian and tritagonist in the 2000 Disney direct-to-video animated film, An Extremely Goofy Movie, her only known appearance (so far). She is one of the important side characters aside from the movie's stars, Goofy and his son Max. She meets Goofy when Max takes him to sign up for a college library card before ditching him, unknowingly allowing his father to get to know her better and, eventually, became his girlfriend.
In the movie, she is voiced by Bebe Neuwirth, best known for her portrayal of Dr. Lilith Sternin on the NBC television sitcom, Cheers and its spinoff, Fraiser.
Sylvia appears to be a beautiful young female dog with a small snout and short lush red hair. Her most common seen outfit is a white button top with a black shirt, wearing a pair of red frame glasses over her dark green eyes. Sylvia also wears a black skirt and 1970s-style black heels.Later on, when dancing with Goofy, she is seen wearing an 1970's inspired outfit, colored mostly green, complete with gold hoop earrings and a large red afro like hairstyle. She also has removed her glasses and has light purple eye liner on her eyelids.
While she is seen as the quiet and well mannered librarian of the college Max and Goofy attends, she is shown to be a fun loving and sweet woman on the outside, quickly revealed by Goofy upon meeting her. She is a fan of old collectibles and shows, same as Goofy, and loves to dance. Eventually, she falls in love for Goofy and is seen as his girlfriend after their first "date" together.
She is shown to have a cold side to her, seen when Goofy accidentally forgot their date when he felt disheartened from Max rejecting him. Since then, she remained cold and distant from Goofy when they met again, though this later faded away after Goofy pleaded for her help. She also values family bonds as she watches in hope at the changes transpiring between Max and Goofy throughout the movie.
