Sue Perkins returns for a second outing of the seasonal challenge in which a group of celebrities make their way to a snowy mountain top to compete in an epic snow sculpture competition. Laurence Llewelyn-Bowen, who competed last year, is also back, but this time he is on hand to offer artistic advice to the hopefuls, while the competitors' efforts will be judged by Swedish sculpting sisters Sara and Emilie Steele and renowned British artist Taslim Martin.
