Doc McStuffins, Ty Burrell

Modern Family's Ty Burrell has signed on to play a very different kind of father on the series premiere of Disney Junior's animated series Doc McStuffins, TVGuide.com has learned exclusively.

McStuffins is about a little girl named Doc who, with her stuffed animal friends Stuffy, Lambie, Hallie and Chilly, helps kids deal with the fear of going to the doctor.

On the debut episode, "Out of the Box," Burrell will provide the voice of Big Jack, a nurturing jack-in-the-box whose son, Little Jack, comes in for a check-up with Doc.
