K.C. Undercover Sneak Peek: Zendaya 'Spies' a Most Fitting Halloween Outfit

K.C. Undercovers titular spy slips into a familiar “costume” this Halloween, as seen in this sneak peek from the Disney Channel series’ “Monstober” episode.

In “All Howl’s Eve” (airing Sunday at 8/7c), while Ernie and Judy travel to New York City’s Central Park Spooktacular to intercept an evil wolf serum, K.C. (played by Zendaya) and BFF Marisa (Veronica Dunne) throw a Halloween bash at the house. Hoping to bolster her confidence in front of River, the new boy in school, K.C. adopts one of her worst “undercover” guises ever, as seen in the clip above.

Peyton List and Skai Jackson (of Jessie/BUNK’D) guest-star, as Emma and Zuri.

Kicking off Disney Channel’s crossover-tastic “Monstober” event, I Didn’t Do It‘s Austin North and Sarah Gilman visit this Friday’s Jessie (airing at 8 pm), followed by Austin & Ally‘s Ross Lynch and Laura Marano popping up on Girl Meets World.

Leading out of K.C. Undercover on Sunday at 8:30, Best Friends Whenever meets Girl Meets World‘s Rowan Blanchard and Peyton Meyer. Austin & Ally then get a visit from K.C.‘s Kamil McFadden and Trinitee Stokes, while Best Friends‘ Landry Bender and Lauren Taylor hang with Liv and Maddie.
