Marthur is a Mash up between Arthur and Martha Speaks. Two Marthur features are available on the PBSKids website, a sticker book and two videos. The videos insert Arthur Read into several scenes of the opening theme of Martha Speaks and vice-versa with the Arthur opening theme. Like Arthur, Martha Speaks is a production of WGBH Boston, and the two share many common writers, including Joe Fallon and Ken Scarborough, who serves as the head writer for Martha Speaks.
