K.C. Undercover Sneak Peek: Can Zendaya Save Christmas?

Zendaya‘s K.C. Undercover character realizes she has made a serious mistake when legendary funnyman George Wallace guest-stars on the Disney Channel series.

In “‘Twas the Fight Before Christmas” (airing Sunday at 8/7c), K.C. thinks she has given her dad (played by Kadeem Hardison) a perfect gift — a surprise visit from his father, Poppa Earl (Wallace) — only to discover the two don’t get along.

As seen in the sneak peek above, K.C. believes she had finally brokered peace between the two, until a text messaging war breaks out.

The Christmastime K.C. is part of Disney Channel’s fifth annual “Fa-La-La-Lidays” programming event, which also includes holiday-themed episodes of BUNK’D and Girl Meets World (on Friday) and Best Friends Whenever, Austin & Ally and Liv and Maddie (on Sunday).

Also, Disney Channel Fa-La-La-Lidays Celebrates a Radio Disney Family Holiday, an aggressively titled special hosted by GMW‘s Sabrina Carpenter, airs Friday at 9 pm.
