Sassy Saddles is tasked with telling the new tale of Hearth's Warming.

The caribou are landing at the town of Lindisbarne. Everypony's throwing them a welcoming celebration and the Canterlot unicorn Sunrise Splendor hopes it'll be exciting in this boring town. She may be getting more than she wishes for.

Zecora's role seems almost the same under the new regime during Nightmare Night. Almost.
