A Very McStuffins Christmas

'Tis the season for cool guest stars on Disney Junior! The wildly popular preschool channel has landed Arrested Development duo Jeffrey Tambor and Tony Hale for A Very McStuffins Christmas, a special holiday episode of the animated hit Doc McStuffins, airing Sunday, Dec. 1 at 6/5c. The plot finds little Doc going to the North Pole to seek help with a broken Christmas present. Tambor does the voice of Santa, Hale is Tobias the elf.

That's directly followed by Oh, Christmas Tree!, a new installment of Minnie's Bow-Toons (6:25/5:25c) where Minnie and Daisy try to outdo each other's tree decorations. Then comes Holiday in Enchancia, a new episode of Sofia the First (6:30/5:30c), with Eric Stonestreet (Modern Family) returning as Sofia's purple flying horse Maximus. A dreadful snowstorm keeps King Roland from coming home for the holidays, so Sofia leads her family on a brave expedition to find him. Of course, she's going to need some assistance from a much more seasoned princess, so who shows up? Princess Aurora, star of the 1959 Disney classic Sleeping Beauty!
