Marthur

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.

Marthur Stickerbook Mashup
Marthur Stickerbook Mashup is a game that allows the player to create their own scenes from Arthur or Martha Speaks by combining characters, items, and backgrounds from both series.

Gameplay
The game is arranged with the work area in the center, with the Martha Speaks stickers on the left and the Arthur stickers on the right. The four buttons are in the center, below the work area. Clockwise from the top-left, the buttons are: delete sticker, clear whole project, print project, save project.

Backgrounds
There are 4 backgrounds from each series, for a total of 8 backgrounds. The Martha Speaks backgrounds are: the inside of a barn, a campsite, the kitchen of Martha's family's house, and a concert stage. The Arthur backgrounds are: the living room of Arthur's family's house, the Sugar Bowl, the hallway of the Tibbles' House, and the inside of the Tree House.
