The new setting of McStuffins Toy Hospital comes to Doc McStuffins when Season 4 premiers Friday, July 29 on Disney Junior (9:00-10:00 a.m. EDT) and  Friday, July 22, on the Disney Junior App. On Saturday, August 6, the first-ever museum exhibit dedicated to Doc McStuffins will open at the world’s largest children’s museum, The Children’s Museum of Indianapolis. The interactive experience, inviting kids and families to explore and learn about healthy habits, compassion and nurturing care, will travel to other venues across the country beginning in 2017.

This news comes as many fans of the show continue the #RenewDocMcStuffins campaign on social media as they hope Disney Junior will renew the show for a fifth season.

Anthony Anderson (ABC’s “black-ish”) and Dawnn Lewis (“A Different World”) guest star in the season premiere, “Welcome to McStuffinsville,” in which Doc’s grandmother transports Doc to the magical world of McStuffinsville where she will carry on a family tradition by expanding her practice to the McStuffins Toy Hospital. There, on her first day as chief resident, Doc must tend to Stanley, a lonely, brokenhearted toy.

Actress and recording artist Amber Riley (“Glee”) performs the new theme song, “Doc McStuffins: Toy Hospital,” in an episode debuting Friday, August 5 (9:30-10:00 a.m. EDT).

Additional guest stars in season four include: Robin Roberts (ABC’s “Good Morning America”), Christopher “Ludacris” Bridges (“The Fast and the Furious”), Molly Ringwald (“Sixteen Candles”), Ellen Pompeo (ABC’s “Grey’s Anatomy”), Gabourey Sidibe (“Empire”) and Vanessa Williams (“The Good Wife”).
