Doc McStuffins

As hit animated pre-school series Doc McStuffins returns for a second season on Sept. 6, Disney Channel and Disney Junior are sending out "The Doc Mobile," a 27-foot Airstream trailer, to promote the show around the country. The Airstream will encourage good health and nutrition, allowing kids to give their toys a "check up" and take part in other health and wellness lessons, such as nutrition and physical development.

The promotion kicks off on Sunday, Aug. 18, at the Franklin Park Zoo in Boston, and will also visit New York, Chicago, San Antonio, Ft. Worth, New Orleans, Atlanta, Washington, D.C., Los Angeles and Phoenix.

Season 2 of Doc McStuffins premieres Sept. 6 at 10 a.m./9c on Disney Channel, and 4/3c on Disney Junior. Geena Davis, Jeffrey Tambor, Tony Hale, Molly Shannon, Sutton Foster, Amy Sedaris and Peter MacNicol are among the actors providing guest voices this season.

Doc McStuffins was the No. 1 cable TV series among kids 2-5 last year, as well as the No. 1 cable TV preschool series in total viewers and women 18-49, according to Disney.
