Marvin the Tap-Dancing Horse is a Korean-Canadian animated television show produced by Nelvana & KBS. It tells the stories of a young horse named Marvin who is part of a carnival. The executive producers, Michael and Betty Paraskevas, are the creators of Maggie and the Ferocious Beast and the book that the show is based on.
He used to be in movies and on Broadway; his first big break was in the musical movie 43rd Street (a takeoff of 42nd Street), although he's not proud of his performance in it.
In the series, he is Edward Larue III's (aka Eddy Largo) best friend.
