In the middle of decorating for the holiday season, Sid (John Leguizamo) accidentally destroys Manny's (Ray Romano) favorite decoration, the traditional Christmas rock (predating the Christmas tree) by accident. Sid, convinced by Manny that he's now on Santa's naughty list, takes off with Crash (Seann William Scott), Eddie (Josh Peck), and Peaches (Ciara Bravo) — who's still a young child — for the North Pole to get him off the naughty list. On their journey, they befriend one of Santa's reindeer Prancer (T. J. Miller).
